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.
