The PSM allows seamless, zero-fee exchanges between USDD and supported stablecoins, starting with USDT. Support for additional stablecoins will be added over time to enhance flexibility and accessibility for users.

#### How to Use the PSM

1. **Select the Stablecoin:** On the PSM page, choose the token you want to exchange for USDD or vice versa.

2. **Enter the Token Amount**: Input the amount of tokens you wish to swap. The transaction requires no service fees; however, ensure your wallet has enough TRX to cover the gas fees for the transaction.
