# Polyflow Overview A PayFi Protocol Linking Real World Assets with DeFi
## Why PayFi? Payment is the leading application for we crypto and needs a new infra to handle compliance challenges, custodian risks, AML implementations as well as new crypto assets DeFi needs a new infra for new yield source, compliance friendly and real world asset integration Payment + DeFi = PayFi Both of them need a new infrastructure layer —> PolyFlow ## **PolyFlow’s PayFi Solution** The fusion of crypto payments and DeFi has given rise to PayFi. PayFi seeks an entirely new infrastructure to support its implementation and address complex compliance issues. Since Solana Foundation Chair Lily Liu introduced the concept of PayFi at the Hong Kong Web3 Summit, PolyFlow has been regarded as one of the pioneering protocols aimed at constructing the financial infrastructure for PayFi. PolyFlow’s core concept revolves around modular design, decoupling the transaction information flow and fund flow previously controlled by centralized institutions. By doing so in a decentralized manner, it enhances compliance with regulatory standards and reduces custody risks throughout the transaction process. Additionally, PolyFlow leverages blockchain features to connect with the DeFi ecosystem, facilitating the widespread adoption of PayFi applications.
## The Current Dilemmas Encountered in Cryptocurrency Payments In the current business model of crypto payments, whether it’s payment solution providers or asset management service providers, most operate in a centralized manner. These centralized institutions lack transparency, and the risk between trading counterparts can easily lead to single points of failure. Additionally, centralized decision-making contributes to widespread custodial risks. These issues have long plagued the industry, adding significant complexity to transactions and causing concern for regulatory agencies: * **Centralized custody:** Institutions holding user-related private keys exposing user assets to significant custody risks. * **Traditional fiat settlement:** The current crypto payment model is transitional and must be integrated with traditional fiat settlement systems, resulting in increased costs and inefficiency. * **Regulatory blind spots:** Opaque centralized institutions, coupled with incomplete cryptocurrency legal frameworks, pose significant challenges for regulation. * **Service limitations:** Single institutions supporting limited categories of cryptocurrency payment services struggle to meet diverse user needs. * **DeFi incompatibility:** Centralized institutions cannot effectively integrate with the DeFi ecosystem, hindering widespread adoption of PayFi. ## Some of the key features of Polyflow include: * A simpler gateway for crypto mass adoption * Custody-free to ensure compliance adherence * Privacy protection leveraging ZK (Zero-Knowledge) technology * DeFi yield generated by supplying liquidity for payment transactions * Proprietary PID Layer to facilitate cross-functional transactions * Comprehensive liquidity pool for settlement execution * Versatile Dapps to expand products and capabilities
## What is a Payment Gateway? A payment gateway is a secure online service that enables businesses to accept and process payments from customers using various payment methods like credit cards, debit cards, or digital wallets…

The proponents of blockchain have long been asserting that this new form of digital finance will rapidly supplant traditional financial systems like SWIFT, Visa/Mastercard, thereby swiftly ushering in a new PayFi financial paradigm on-chain. At PolyFlow, we take a more nuanced perspective. While we recognize the potential benefits of blockchain, we also understand that such a transformation won't happen overnight. PolyFlow plays a dual role in achieving its mission and vision of promoting crypto payments. As the infrastructure for PayFi, we focus on providing foundational services to support PayFi projects. Simultaneously, we aim to strengthen connections among people by creating scenarios where consumers can utilize crypto for payments. This dual approach reflects our commitment not only to reducing costs and enhancing efficiency at a business level but, more importantly, to enhancing utility for crypto holders at a consumer level. In doing so, we aim to advance the use of crypto in payments and strive for a more inclusive financial future. *** ## Pay with Crypto, Earn the Future As we gradually roll out our Season Campaign, starting with the Seed Campaign, we will collaboratively map out a Network State Consumer Guide based on the concept of Network State. This guide will enable consumers to identify regions and merchants that accept crypto payments and earn reward points for their crypto purchases. This initiative offers merchants the benefits of crypto transactions, including instant settlement, 24/7/365 real-time fund transfers, and lower transaction fees compared to the 1.5-3% typically charged by credit card payments, along with the advantage of no chargebacks and a global reach. Additionally, through PolyFlow's incentives, consumers can access a guide to navigating the crypto landscape, further enhancing the interaction between cryptocurrency and the real world. The above focuses on "Pay with Crypto," and as we progress further, the "Earn the Future" concept takes shape. It emphasizes financial inclusion and equity by reducing friction in traditional payment pathways through crypto payments. The savings from these reduced friction costs are returned back to consumers as token incentives, similar to the concept of Worldcoin, fostering global unity and universal basic income (UBI). This approach enhances financial inclusion by ensuring that crypto payments and financial services are accessible to anyone with internet access, thereby promoting financial equity. Any partner that advances consumer crypto payments will become a contributor to the Network State Consumer Guide, whether you are an exchange, wallet, payment institution, a single merchant or a single consumer. Together, we are building the next-generation PayFi financial cluster.
*** ## PolyFlow DAPP With this initiative, we are launching PolyFlow Dashboard, which intends to be a central hub for consumers navigating their crypto future within the Network State. Through this Dashboard, consumers can check in and engage in interactive activities to earn points, build an on-chain profile, as well as access the Network State Consumer Guide, thereby further advancing the development of the Network State through crypto payments and on-chain financial services. **Dashboard** * **Definition:** A Dashboard is a user interface designed to display key information and data. It serves as a platform where users can log in and access their account details. * **Function:** Users can view their accumulated PolyFlow points on the Dashboard. This feature provides users with a clear and accessible record of their points, enabling them to easily track their progress and status at any time. Through the Dashboard, consumers can not only view their accumulated PolyFlow points but also upload their consumption records using the core interactive feature, “Scan to Earn.” This contributes to the development of a Network State consumer payment network. **Scan to Earn** * **Definition:** This is the core interactive feature of the Dashboard, allowing users to scan and upload their consumption records. * **Technical Implementation:** It employs AI scanning, and other advanced image recognition technologies. After a purchase, users can simply scan their receipts (such as physical receipts or electronic payment vouchers) using their mobile phones or other devices and upload the records to the platform. * By uploading consumption records, users can earn points or other rewards. * Users can upload their records at[ app.polyflow.tech/scan-to-earn](http://app.polyflow.tech/scan-to-earn). The goal of the Dashboard is to transform every receipt into PolyFlow Points, thereby fueling the future of PayFi. By earning points and unlocking rewards, we collaboratively work toward building a borderless payment infrastructure. Every transaction counts, and each expenditure contributes to shaping the PayFi ecosystem. *** ## Season Campaign PolyFlow is now gearing up to launch the Season Campaign, marking a pivotal step in promoting crypto payments and heralding a paradigm shift in on-chain finance. This initiative highlights the core significance of PayFi as we delve into its transformative impact on traditional payment and financial systems, paving the way for revolutionary changes in how we transact and manage finances. Here are our primary focus areas: **Payment On-Chain** To fully leverage the blockchain, we must integrate real-world payment scenarios into the blockchain ecosystem. Although crypto adoption rate is on the rise alongside industry expansion, it has yet to reach optimal levels. Therefore, the initial phases of PolyFlow's Season Campaign will focus on encouraging the use of crypto for everyday transactions. This initiative will lay the groundwork for a more widespread and seamless on-chain payment experience. **Building On-Chain Profile** As more economic activities and payments migrate to the blockchain, the data from these transactions will form users' on-chain profiles—PolyFlow PID. Previously, valuable consumer data was monopolized by centralized financial institutions, generating profits for them while remaining inaccessible to users. Now, through decentralization, PolyFlow empowers users to regain control of their data and unlock its potential benefits. Whether developing a personal on-chain credit system or earning income by authorizing data to AI, these will be the focal points of our future Season Campaigns. Our aim is to provide users with true ownership and control over their financial data. **Financial Service for Everyone** Blockchain-based payments signify not only a transformation in payments but also a revolution in financial services. By harnessing the composability of blockchain technology, we can establish a novel PayFi financial service ecosystem accessible to any internet user. This ecosystem will encompass a wide array of services, including payments, savings and wealth management, lending, remittances, and ecosystem governance. Our ultimate goal is to achieve genuine financial inclusion and equality, making comprehensive financial services available to all. This is the vision PolyFlow is committed to realizing through our Season Campaign. By concentrating on these three key areas, PolyFlow's Season Campaign aims to propel the adoption of PayFi and pave the way for a more inclusive, efficient, and user-centric financial future. The PolyFlow Dashboard serves as this central hub, helping to realize our vision step by step. *** ## Call to Action "Pay with Crypto, Earn the Future" is more than just a slogan; we are actively implementing it. We are starting small with the pilot Seed Season, gradually building our on-chain financial paradigm until it evolves into a significant force. # User Guide

The same was true for double-entry bookkeeping and joint-stock companies in their early days. However, like these innovations, blockchain is an apparently mundane process that has the potential to fundamentally change how individuals and businesses collaborate. # White Paper From「Scan to Earn」to 「Mint to Earn」 When we flipped the switch on PolyFlow’s “Scan to Earn” season in late April, no one expected crypto payments to lunge forward this fast. In a matter of weeks, Washington passed the GENIUS Act, setting the golden standard for stablecoins. Circle rang the Nasdaq opening bell the next morning, its market cap topping $10 billion before lunch — a symbolic handshake between Wall Street and crypto. Visa, PayPal, and Stripe answered with their own starting-gun announcements: on-chain settlement pilots that move billions in stablecoins across borders in seconds. The moment legacy incumbents clear B2B invoices on-chain, “Pay with Crypto” stops being a slogan and becomes a tidal wave washing away yesterday’s rails. > Since its launch in late April, “Scan to Earn” has attracted over 1,000,000 participants, generating tens of millions of scans across real-world payment scenarios worldwide. From daily coffee purchases to international boarding check-ins, each scan powers the PolyFlow PayFi network and underscores the global demand for seamless crypto payments.
The convergence of these external variables has transformed **“PayFi”** from an abstract concept in a whitepaper into a tangible industrial pathway: **Stablecoin Payments** address the question of *“How can funds settle instantly, and how can records remain compliant?”*; **On-chain Finance** answers *“What can be done with the funds once they arrive?”* When these two gears interlock seamlessly, the user experience is distilled into simplicity at the front end — while behind the scenes lies a sophisticated backend architecture of real-time risk control, automated market making, yield aggregation, and identity verification. > This marks the **2.0 vision of “Pay with Crypto, Earn the Future”**: *Payments become mining. Spending becomes investing. Data becomes property rights.* Cue the “Mint to Earn” season. One question remains: once crypto payments feel as mundane as tap water, how does the average person actually “earn the future”? The answer is an On-chain Profile. For twenty years, Visa and Mastercard poured hundreds of billions into rails, stockpiling the world’s richest consumer data — and kept every cent of upside for themselves. Users never saw their own data, let alone profited from their creditworthiness. Blockchain writes “data portability” into its base layer. PolyFlow PID (Payment Identity) writes every on-chain payment, every coupon burn, every mile flown directly into the user’s profile. Think of it as Web3’s “Sesame Credit.” Buy a latte in Bangkok with USDC and the chain quietly logs timestamp, geocoords, merchant category, spend, and gas-discount rate. Mint a flight via PID on a Web3 travel app and the dataset swells with airline tier, seat preference, rebooking cadence, and carbon offsets. Zero-knowledge proofs compress the fragments into PID — private by default, shareable on demand. Need an on-chain credit line? Hand your PID to a DeFi protocol, its ML model scores your cash flow and issues a real-time limit. Want to monetize your preferences for AI training? License the sanitized data to a federated-learning model and collect rent per inference. To jump-start the flywheel, we’ve teamed up with Web3 travel platform Umy.com. One click mints legacy loyalty tiers into on-chain PIDs and unlocks triple yield: 1. The same airline upgrades and late checkouts you already enjoy. 2. Coupon airdrops are tied to the newly minted status. 3. In the near future, encrypted PID shards will be uploaded to the PolyFlow data market. When an AI firm queries the “high-frequency business traveler” dataset, you will earn USDC royalties proportional to usage. At no point will you need to interact with wallets, private keys, or gas fees; you simply scan your boarding pass while the backend silently mints, authorizes, and splits revenue. “Mint to Earn” is only the opening act. Once identity is on-chain, users can plug into tomorrow’s financial stack without friction. Imagine: A Shopify plugin that swaps USD checkout flows into USDC in real time and one-click stakes the proceeds in an on-chain money-market fund. A Starbucks “coffee bond”: pre-pay 100 USDC to mint an NFT card redeemable for 102 USDC in 30 days, the yield sourced from floating interest in on-chain lending pools. A UN-WFP refugee-cash program that uses zero-knowledge proofs on PID to verify beneficiaries and airdrops USDC directly to wallets, eliminating leakage and graft. When the curtain falls on “Mint to Earn,” we will raise it again on “Yield to Earn,” closing the loop from payment rail to asset allocation and turning “Earn the Future” from manifesto into measurable APY. Only when crypto payments are as invisible as Wi-Fi, on-chain identity as portable as a passport, and every purchase a vote for tomorrow will we have reached PayFi’s promised land: an open financial era where data is self-sovereign and yields are shared. PolyFlow simply opens the door and says — > Welcome to the future. Please mint to earn it. # User Guide ## Mint to Earn Overview Through the zkPass protocol, users can verify their off-chain platform data (e.g., social accounts, travel, business trips) to generate a zero-knowledge proof credential (zk-VC), which is then stored on-chain.\ This credential serves as a verifiable credit carrier, helping users build decentralized credit profiles.\ When verification is successful and meets the rules, users can earn token rewards — this is Mint to Earn. ## Verification Flow & Rules
#### 1. Data Verification & Credential Generation * Users choose the data source to be verified (e.g., Twitter follow @PolyFlow). * zkPass uses zkTLS technology to directly access HTTPS data sources and generate a zero-knowledge proof confirming data authenticity. * The credential only includes verification results (e.g., Twitter Follower Count) rather than raw data. Raw data never leaves the user’s device, ensuring full privacy protection. #### 2. On-Chain Storage & Reward Trigger * Credentials are stored on-chain via smart contracts as publicly verifiable records, while rewards are distributed automatically. * Uniqueness constraint: the same data source (e.g., Twitter Blue Badge) can only be uploaded once. Duplicate attempts are blocked. #### 3. Validity & Renewal Mechanism * On-chain credentials have a 2-year validity period ⏳. After expiration, re-verification is required to update credit records and maintain data accuracy. * If verification fails or conditions are not met, users can re-submit unlimited times until successful. ## Using the zkPass Plugin ### **1. PC (Highly Recommended)** Recommended setup: * Browser: Latest Google Chrome or Brave
**Instructions:** * Option 1: Install **TransGate** from the official Google Chrome Web Store.\ **⚠️ Important:**\ Do not install TransGate extensions from third-party sources.

This gap between digital assets and everyday spending keeps mass adoption at arm’s length. One of the most practical answers now appearing is the crypto card: a useful product that lets you pay with crypto (or any supported token) without the need to convert.
PolyFlow’s answer is the [**PolyFlow Crypto Card**](https://app.polyflow.tech/card), the flagship of our “Pay with Crypto, Earn the Future” campaign, which will serve as a cornerstone of the initiative, becoming a primary vehicle for the mainstream “Pay with Crypto” movement. Here’s how it works. The card is tied to a self-custodial wallet; the moment you tap, insert, or swipe at a terminal—or type the digits into an e-commerce site—the provider liquidates the exact crypto sum needed, swaps it into local fiat at the live market rate, and settles the transaction in milliseconds. Need cash? Stick the same card into a compatible ATM and the same instant conversion occurs before the bills come out.

# Intro PID——Redefine Your Crypto Wallet The call for crypto mass adoption has echoed for years, yet blockchain remains an isolated realm, disconnected from everyday digital life. Even with Web3's development of strong tools and infrastructure, the majority of users are still entrenched in Web2's centralized platforms, which govern their data and form isolated data silos. Web3 has not yet delivered on its promise of user ownership, as it struggles to leverage existing real-world data effectively without compromising user privacy or introducing new trusted intermediaries. Until now, with the launch of [PolyFlow's PID](https://polyflow.medium.com/unveiling-pid-polyflows-game-changer-in-payfi-shortened-5af9685ffdc9) incorporating Zero-Knowledge Proof (ZKP) and attestation services technologies, existing data from Web2's centralized platforms can now be utilized on-chain while also acting as a bridge for Web3 applications to operate off-chain. [PolyFlow](https://polyflow.tech/), as a Consumer PayFi infrastructure, seeks to seamlessly bridge the on-chain crypto realm with the off-chain real world using blockchain technology. Starting with seamless crypto payments, it extends into on-chain financial services and beyond. In this endeavor, PolyFlow PID serves as an essential component. *** ## Why PID Matters? Decentralized Identity (DID) represents a revolutionary approach where individuals generate a public-private key pair to create a DID Document, housed on decentralized networks like blockchain. This shift from centralized control to individual ownership embraces self-sovereignty. In PolyFlow’s PID system, users link credentials to their DID, stored as Verifiable Credentials (VCs), ensuring privacy during verification while maintaining asset ownership. PID is a DID tailored for payments, connecting real-world identities with crypto wallets. It enables users to store, verify, and manage existing real-world data in the form of digital credentials, meeting compliance requirements while safeguarding privacy and promoting self-sovereignty. As [PolyFlow co-founder Raymond](https://polyflow.medium.com/an-interview-with-raymond-qu-how-polyflow-enables-payfi-6ad2838efc85) highlights, “PID should function like a physical wallet, holding cash, IDs, credentials, and cards.” In this context, PID’s potential applications are extensive, offering a versatile tool for the evolving digital landscape. *** ## Call to Action For crypto to become mainstream, it needs to address users' needs on the existing broad internet. PID lays the foundation for this by enabling encrypted trust from existing real-world data without third-party involvement, offering privacy-preserving user-controlled verification, and creating a composable identity layer. PID not only redefines crypto wallets but also reshapes the boundaries between Web2 and Web3. This paves the way for new applications based on verifiable real-world interactions. As our online lives become increasingly accessible through verifiable claims, a new wave of applications will thrive, offering users greater control, reducing friction, and unlocking true value. PID represents more than just another protocol; it embodies a new approach to how information moves between platforms and how trust is built in this new digital ear. A series of PID-related tasks will soon be released on [PolyFlow’s DAPP](https://app.polyflow.tech/), inviting users to explore PID use cases with us. Stay tuned. # PID Use Case SIM Verification Traditionally, activities such as opening an eSIM card or applying for a credit card require separate KYC processes for each platform. PID streamlines this by enabling cross-platform verification through VCs, thereby reducing redundancy and compliance costs. At PolyFlow, we integrate the Solana Attestation Service (SAS) to enable our clients to anchor transaction proofs and participant credentials directly on-chain, ensuring every payment is traceable, verifiable, and tamper-proof. By combining PID and SAS, PolyFlow powers [ROAM](https://www.weroam.xyz/)—a DePIN open wireless network using OpenRoaming and eSIM—to issue and verify on-chain credentials for SIM cards. When a KYC-verified user requests a ROAM phone plan, the verifier securely validates the on-chain attestation to approve SIM issuance without requiring the user to undergo KYC again. This process ensures that each ROAM SIM is issued only to verified users, mitigating fraud risk and automating credential checks in a decentralized, privacy-preserving manner. Beyond current ROAM eSIM card verification, the PID + SAS integration can support a wide range of future scenarios: * **DeFi Lending & Credit Scoring** Record users’ on‑chain credit behaviors (repayment history, collateral performance, etc.) in PID attestations, enabling lending protocols to plug in trusted credit scores instantly. * **Supply Chain Finance Certificates** Anchor proofs of authenticity for invoices, warehouse receipts, or bills of lading on‑chain via SAS, allowing financiers to disburse funds faster and reduce fraud risk in trade finance and factoring. Additionally, with Zero-Knowledge Proof (ZKP) technology, PID ensures privacy protection, allowing verification without disclosing sensitive information, such as age confirmation without revealing full ID details. This maintains a balance between compliance and privacy, ensuring secure, efficient interactions. *** ## How to Integrate SAS ### User Flow Overview User → Roam KYC (completed via PolyFlow) → PID Credential Issuance (recorded on SAS) → On-chain Verification → Automatic Premium eSIM Activation ### Process Description 1. **PID Integration and Verifier Initialization** The PID system integrates the SAS SDK and initializes a Verifier account, which is responsible for signing and generating PID credentials for verified users.
2. **On-Chain Attestation Generation** Upon successful KYC verification via PolyFlow, an on-chain attestation is generated for the user.
3. **Attestation Submission to Solana** The attestation transaction is submitted to the Solana network via RPC, ensuring transparency and immutability.
4. **Premium eSIM Request Handling** When the user requests a Premium eSIM, the system retrieves the relevant Attestation ID on-chain.
5. **Verification and eSIM Activation** The system verifies the authenticity of the attestation on-chain. Upon successful verification, the Premium eSIM is automatically activated for the user. # Identity Issuer Ref ## zkVC * **Intro** * [zkVC verification system](https://chromewebstore.google.com/detail/zkvc/iehfkbjomoflpblfjahapnfoiackmhnm) is a carefully designed system that utilizes the user's existing KYC information and employs zero-knowledge verification techniques to generate KYC verification credentials without disclosing any of the user's private data. * **Category** * ZK Verification ## CuteID * **Intro** * CuteID is a complete RegTech solution that provides KYC services for DeFi businesses through a ZK-enabled solution for data privacy protection, thus helping DApps to operate in a regulated territory in a compliant manner. * **Category** * Full-KYC * **Verification** * KYC Registration Contract Address: [**https://arbiscan.io/address/0xA55Fb3826457623fba8082F7dF6f3C56Ad9d5CC9**](broken://pages/0e8HCBBhxJtB5TuFIeg9) * KYC Registration Retrieval Function: ```solidity function getStatusAndExtraInfo( bytes32 id ) public view returns (AccessStatus status, string memory extraInfo) ``` * **VC Signature Pub Key** * 0x41AA5d7A43E634c372CA1eaC9F0b3CE391F2B559 # Intro ## What is PLP? PolyFlow Liquidity Pool is a real utility driven yield creation mechanism not based on speculation; PolyFlow built smart contract addresses to facilitate transactions, cutting out the 3rd party processor and retaining processing fees to be paid out as yield. Fully autonomous smart contract driven pool ensures greater decentralization, lower custodial risk, lower third party costs.
## **Materializing RWA Returns On-chain** PLP can be considered a risk-free DeFi income product suitable for on-chain cash flow management. This is an unprecedented breakthrough, as previous DeFi yield models inherently carried risks. For instance, financial products based on decentralized exchanges always faced the risk of impermanent losses, and collateral in on-chain lending products could be impacted by volatile underlying asset prices. These are very common scenarios within the DeFi ecosystem. PLP directly generates risk-free income from transaction fees in real payment scenarios. For example, in a payment gateway context, when consumers make payments to the smart contract address within PLP, liquidity providers can earn payment-related rewards by settling funds in case of merchants requesting early payments. Most importantly, this process is risk-free, with the yield determined by the ratio between liquidity providers’ funds and total transaction volume. PLP can offer attractive fixed or flexible-term financial products, supporting supply chain finance, wallet settlement networks, stablecoins, insurance, and other innovative applications within the PayFi ecosystem. ## Notable Features * Auto-generated contract-based asset vault with non-privileged access * Automated vault assignment program to maximize vault reusability and leverage the degree of decentralization * Fund solely controlled and guarded by contracts * Status informed and executed by non-privileged system * Assets are stored in decentralized vaults and stay intact # Ecosystem Participants ## **Payment-realated Projects** * Those projects are the direct user of our protocol. It integrates our protocol to implement crypto payment collection and other related services. * Those projects incur transaction fees during the usage process. * Those projects receive the pfToken minted by the protocol. * Those projects must be PID holders and meet certain other PID validation requirements. * Those projects need to pre-create their own wallet address in the PLP system. ## **Merchant** * The merchant is the direct user of the gateway. They use the gateway to accept crypto payments. * The merchant has their own account and fund account within the gateway. * The merchant can withdraw their funds from the gateway. * The merchant uses the wallet addresses allocated by the gateway to receive crypto payments. ## **Customer** * The customer is the direct user of the merchant. * The customer is the source of requests for wallet address allocation from the gateway. * The customer’s identity verification needs to be completed by the merchant. ## **Web3 User** * Web3 users can participate in liquid staking to provide liquidity for the fast redemption of pfUSDT and enjoy a share of transaction fees and platform revenue. * Ordinary users can perform a fast exchange between pfUSDT and USDT through the liquid staking pool. * Ordinary users can stake Polyflow Governance Tokens to earn platform revenue. # PLP Mechanism {% content-ref url="/pages/0voI3KOk9D0stYzHpmZt" %} [PF Token](/payment-liquidity-pool-plp/plp-mechanism/pf-token) {% endcontent-ref %} {% content-ref url="/pages/7ig7X6ZDMXR07km6PHZH" %} [Wallet Creation Workflow](/payment-liquidity-pool-plp/plp-mechanism/wallet-creation-workflow) {% endcontent-ref %} {% content-ref url="/pages/nVLDac19c2X4X3nGTEz2" %} [Receive Crypto Workflow](/payment-liquidity-pool-plp/plp-mechanism/receive-crypto-workflow) {% endcontent-ref %} {% content-ref url="/pages/oJ7WG2JrTWOhSmaYxlfV" %} [Withdraw Crypto Workflow](/payment-liquidity-pool-plp/plp-mechanism/withdraw-crypto-workflow) {% endcontent-ref %} {% content-ref url="/pages/yaqBdRrdYzgHmKO3znYm" %} [Fee Distribution](/payment-liquidity-pool-plp/plp-mechanism/fee-distribution) {% endcontent-ref %} # PF Token * pfToken is a token minted by the Polyflow protocol, which is always pegged 1:1 with the supported settlement BN tokens of the protocol. * Depending on the scenario, we may have pfUSDT, pfUSDC, pfDAI, etc. * pfToken is a **rebasable token**, where the funds for the rebase come from protocol-generated revenue. # Wallet Creation Workflow
1-1. Payment Gateway requests PLP core contracts for wallet creation and passes 'owner address', 'number of wallets' as main parameters. 1-2. PLP creates wallets and returns those addresses {% hint style="warning" %} Wallets are basically smart contract {% endhint %} # Receive Crypto Workflow
{% hint style="warning" %} **Fund Monitoring Service** 1. The primary responsibility is to monitor the incoming fund flow to the specified wallet and notify the gateway about the deposit to the relevant wallet. 2. This service can be provided by the project team, Polyflow, or any third party. **Aggregation Trigger** 1. The wallet aggregation method is an on-chain function that helps aggregate all funds pending aggregation in the wallet and notifies the minting of pfToken. 2. This method can be triggered by any on-chain address. 3. There will be an incentive for aggregating a portion of the funds. {% endhint %} ## **Wallet distribution** 2-1. The customer arrives at the integrated merchant of A Gateway to select products and prepare for checkout. 2-2. The merchant requests A Gateway to allocate a dedicated payment wallet for the order. 2-3. The merchant allocates Wallet X from the pre-created wallets to the merchant. 2-4. The customer makes a transfer payment to Wallet X. ## **Fund Monitoring** 3-1. A third party or A project's own fund monitoring backend monitors the incoming transactions to Wallet X. 3-2. Notify A Gateway. ## **pfToken Minting** 4-1. Any address can call the aggregation method of the wallet address, which by default aggregates all available amounts. 4-2. Wallet X will transfer USDT in the wallet to the core contract. 4-3. The PLP contract will mint pfUSDT based on the aggregated amount and give it to the wallet owner (A Gateway). # Withdraw Crypto Workflow
{% hint style="warning" %} **Redemption Cooldown Period** 1. The purpose of setting a redemption cooldown period is to prevent large-scale funds from entering the system and quickly exiting before or after a rebase, effectively draining a large portion of the pool's profits. 2. The duration of this cooldown period is to be determined, and further discussion at the business level is needed. **Directed Redemption Feature** 1. In normal redemption within the PLP system, the initiator of pfToken redemption can specify another address as the recipient of the redemption request, allowing the recipient to claim the redeemed USDT from the contract. 2. During the fast redemption process within the staking pool (pfToken-USDT Swap), the initiator of the redemption can specify the recipient of the USDT after the swap. The transaction will directly transfer the swapped USDT to the designated user. {% endhint %} ## **Refund/Withdrawal** 1-1. The customer initiates a refund request to the merchant. 1-2. The merchant initiates a withdrawal request to A Gateway. {% hint style="warning" %} In this version, both the merchant processing the user refund and initiating their own withdrawal are essentially the same action, requiring A Gateway to withdraw USDT or pfUSDT from the Protocol and provide it to the merchant. {% endhint %} ## **Fast Redemption** 2-1. A Gateway calculates the corresponding pfUSDT amount for the user’s withdrawal request, then initiates a fast exchange with the PLP Staking contract, specifying the recipient address. 2-2. The PLP Staking contract transfers USDT from the pool to the merchant. ## **Normal Redemption** 3-1. A Gateway calculates the corresponding pfUSDT amount for the user’s withdrawal request, then initiates a redemption request to the PLP core contract, specifying the redeeming address. 3-2. After receiving the redemption request and verifying its accuracy, the PLP core contract calls the burn method of the pfUSDT contract to destroy pfUSDT. {% hint style="warning" %} Once the burn process is completed, the PLP core contract locks the corresponding USDT for the user. {% endhint %} 3-3. After the redemption window expires, the merchant can initiate the redemption to receive the USDT from the PLP core contract. ## **pfUSDT Redemption** 4-1. A Gateway may choose to directly transfer pfUSDT to the merchant. {% hint style="warning" %} The merchant will then need to initiate the redemption request and redeem the funds. {% endhint %} # Fee Distribution ## **Transaction Fees** * A transaction fee is incurred each time pfUSDT is minted. * The fee is proportional to the minted amount. * The total fee rate, **0.5%**, is adjustable, but any changes can later be decided through multi-signature or Governance Token voting decisions. * **Fee = *****X*** x **0.5%** ## **Fee Breakdown** 1. **0.25%** remains in the wallet as the protocol's natural revenue. 2. **0.03%** is minted into pfToken and given to the Polyflow treasury. 3. **0.2%** is minted into pfToken and given to the liquid staking pool. 4. **0.02%** is minted into pfToken and given to the user who called the aggregation method. # Intro Imagine a yield that's not subject to speculation. Risk free yield backed by payment transaction processing fees is what powers our staking program. Every transaction will create a bit of processing fee. The total fee will be split amongst our staking program participants. ## Yield **Native Yield from pfUSDT in the Contract**: This refers to the yield generated from holding pfUSDT within the contract, which may include staking rewards, protocol-generated income, or interest earned. **Transaction Fees from Fast Exchange**: Fees generated from users utilizing the fast exchange functionality within the contract. These fees contribute to the revenue pool. **Protocol Core Business Logic Fees**: A portion of the fees generated by the core activities of the protocol, such as minting pfTokens, aggregating funds, or other services provided by the protocol. # Staking Workflow
## **Stake** 1-1. The user calls the contract's stake method to transfer USDT into the contract. 1-2. The user receives **USDT-pfUSDT-LP tokens** in return as proof of staking. ## **Swap** 2-1. The user can call the contract's swap method to exchange USDT for pfUSDT or vice versa. * The swap method can specify a recipient address. * **User exchanges for pfUSDT**: * **0% fee** * The exchangeable amount = The amount of pfUSDT available in the pool. * **User exchanges for USDT**: * There is a redemption fee, which could be determined by a curve (fee model). * The exchangeable amount = The amount of USDT available in the pool. 2-2. The user receives **USDT or pfUSDT** in return. ## **Unstake** 3-1. The user calls the contract's unstake method to transfer **USDT-pfUSDT-LP tokens** back into the contract. 3-2. Based on the token quantity, the contract redeems a proportional amount of USDT or pfUSDT to the user. # Backers CE Innovation Capitals, Hash Global, Stellar Foundation and Community Fund, ZC Capitals, and Meters Network provided over $5 million in funding support during the early stages.

It connects real-world identities with on-chain wallets, allowing users to store, verify, and manage their digital credentials. This ensures compliance with regulatory requirements while safeguarding privacy and promoting self-sovereignty.Some key features of PID include: * Regulatory Compliance: Integrating validation information across various platforms to simplify the verification process. * Privacy Protection: Utilizes technologies like zero-knowledge proofs to comply with AML (Anti-Money Laundering) and CTF (Counter-Terrorism Financing) obligations without exposing user privacy. * Data Sovereignty: Returns on-chain behavioral data to users, allowing them to maintain control over their personal information. * AI-Driven Insights: AI can analyze transaction data linked with PID to provide additional value for its owners and assist in establishing on-chain credit systems. PID plays a crucial role in bridging traditional finance and DeFi ecosystems, offering a means to handle tasks such as identity verification, regulatory compliance, privacy protection, data sovereignty, and more. * **How do I obtain a PID?** Users can mint PID at * **Once I have my PID, what can I do with it?** 1. Minting Process: 2. The user mints a PID (Personal Identification). 3. The user enters the personal center and follows the guidance to complete required services, such as KYC (Know Your Customer). 4. The user selects a KYC vendor, such as Sumsub. 5. After completing the KYC process, the user receives proof of completion, which can be stored either on-chain or off-chain. 6. This is now your entry ticket to the PolyFlow world which will feature usage at payment gateways, liquidity provider staking, air drops and more as we build out our ecosystem. 7. Basic KYC Interaction Process: 8. The user, holding a PID, enters a specific project to participate in financial services. 9. The service provider obtains the user's relevant KYC or compliance proof through the blockchain or an interface. 10. The service provider verifies the validity and authenticity of the proof with the relevant vendor. 11. Once validated, the user is approved and allowed to use the related services without having to do an extra KYC from the provider. * **Which chain can I mint my PID on?** A user can possess multiple PIDs, with each blockchain address corresponding to a distinct PID, and each PID is soul-bound to its respective address. Currently, you may mint on **Ethereum, Tron, Scroll, Polygon, X Layer, Berachain, Bevm, Bitlayer, Kroma, Base.** * **How does PID present my information to third parties?** All these PIDs can be linked to a single user account, wherein the user's KYC information is centrally stored by PolyFlow without any alteration. This KYC information is directly associated with the user's account, and users have the flexibility to actively assign the stored KYC information to their held PIDs.The user, holding a PID, enters a specific project to participate in financial services. The financial service provider obtains the user's relevant KYC or compliance proof through the blockchain or an interface and verifies the validity and authenticity of the proof with the relevant vendor. Once validated, the user is approved and allowed to use the related services. * **Does PID use my sensitive information?** PID won't keep or use any of your sensitive information. Upon completion of a valid identity verification process through Polyflow partners, an identity Proof ([verifiable credentials](https://www.w3.org/TR/vc-data-model-2.0/#what-is-a-verifiable-credential)) is generated and sent back to you. This identity proof doesn't contain any sensitive information and is managed by you. * **How does my PID calculate my onchain credit?** On-chain credit is similar to our 'trading score'. Currently, we cooperate with TrustaLabs and use their on-chain media score system to calculate and evaluate this on-chain score.
**PLP FAQ** 1. **What is PLP?** The Payment Liquidity Pool (PLP) is designed to manage the flow of funds in payment transactions. It utilizes smart contracts to autonomously handle fund custody, providing a secure and compliant framework for the movement, custody, and issuance of digital assets.Key features of PLP include: * Decentralized Custody: PLP provides a means for decentralized fund custody, eliminating reliance on expensive enterprise wallets traditionally used by centralized institutions. * Liquidity Pool: By aggregating transaction funds via smart contracts, PLP supports the liquidity needs of payment transactions, facilitating financing in these processes. * DeFi Compatibility: PLP is built to seamlessly integrate with the DeFi ecosystem, introducing DeFi logic into PayFi applications. * Risk-Free RWA Yield: The protocol generates yield directly through real-world transaction fees, offering a stable and risk-free revenue source for DeFi markets. PLP aims to reduce the entry barriers for businesses to Web3, allowing more innovative applications such as supply chain finance, wallet settlements, stablecoins, and insurance to flourish within the PayFi ecosystem. 2. **Where is the technical documentation for using the API?** API documents are not yet available, will be made available when we officially open up the liquidity pool for public usage. 3. **What are the main benefits of my project to using PLP?** The main benefits of using the PolyFlow Liquidity Pool (PLP) include: * Risk-Free Yield: PLP generates stable, risk-free yield based on real-world transaction fees, offering a secure income source within the DeFi ecosystem. * Decentralized Custody: Provides secure and compliant asset custody, minimizing the need for traditional intermediaries and expensive enterprise wallets. * Liquidity Provision: By aggregating transaction funds through smart contracts, PLP supports the liquidity needs for payment transaction financing. * Composability and Scalability: Enhances the DeFi ecosystem's adaptability, allowing PayFi applications to seamlessly integrate and grow within the rapidly evolving digital asset landscape. * Cost-Effectiveness and Efficiency: By maintaining a static fund flow pooled within PLP, it reduces costs and increases the efficiency of financial transactions. 4. **What kind of costs are there associated to using PLP?** Gas cost during wallet creation (paid by merchant)Gas cost during fund collection (can be paid by on-chain users)Gas cost during pfUSDT redemption (paid by pfUSDT holders) There are no costs associated with using PLP. On the contrary, using PLP can significantly reduce your expenses by replacing your existing enterprise wallet solution. 5. **Why should I even consider using PLP to handle my payments needs?** All fund-related functions and processes are managed by smart contracts. For merchants, we engage in a decentralized infrastructure that promotes self custody and instant redemption of funds. Compare to other centralized entities where settlement might take 3 to 7 days or more. Because funds are no longer transferring wallet to wallet, it bypasses the network traffic and can provide a much smoother transaction experience for users.The current PLP offers crypto collection, wallet allocation, crypto custody, and accompanying voucher redemption functionalities.
## **Staking FAQ** 1. **What's the yield that I can expect?** The source of yield comes from payment transaction fees. PolyFlow decentralizes the process, returning the fees typically associated with traditional payments back to the protocol, which then distributes the yield to participants according to predefined rules. 2. **What are the prerequisites for participation?** There are no prerequisites for participation. 3. **What are the risks for this staking program?** There is literally no risk in this staking program as the yield is backed by processing fees, not speculation. 4. **Where is my principal held?** The principal is held inside the staking contract but it will be used as liquidity support for pfUSDT/USDT swap. You will get an LP token representing your principal that can be used to withdraw whenever you want. 5. **What is the lockup period, and how long does it take to unlock?** The Staking doesn't have any lockup period. You may redeem your principal at any time with no delays. 6. **How does the Staking program generate yield?** The staking program generates yield through three sources. * Liquidity support processing fee * pfUSDT holders will swap their pfUSDT for USDT for an instant liquidity unlock. This process will cost them some process fees and those fees will be compounded into the staking program. * Protocol Reward (pending) * Polyflow will incentivize staked users with governance token rewards. * pfUSDT Natural Yield * All those pfUSDT in staking protocol will keep their rebasing scheme which will generate natural yield for all those stakers.
