* Exchange Formula in Volatile Pool (Constant Product): x \* y = k, where x and y are balances of TON and USDT, respectively.

**Step 2: Exchange USDT to AquaUSD**

* Using Dedust Stable-Swap Pool: Exchange USDT to AquaUSD in Dedust Stable-Swap Pool.
* Exchange Formula in Dedust Stable-Swap Pool: x^3 \* y + y^3 \* x = k, where x and y are balances of USDT and AquaUSD, respectively.
