### Sustainable Swap
**Chain native ERC20.** GASSSS Swap is a minimal Uniswap V2 style AMM deployment tailored for Stable Mainnet, where the gas token `gUSDT` and the governance token `STABLE` are exposed as an ERC20 like contract.
**STABLE Buyback Flywheel.** GASSSS routes protocol value back into the governance token via a `Treasury` controlled buyback. The `Treasury` can burn GASSSS LP tokens, receive the underlying assets, and swap a default half of the value into STABLE.

### Learn more about the gas sponsorship
Stable Mainnet uses `gUSDT` as the gas token. Many users hold the governance token `STABLE` but do not hold `gUSDT`, and acquiring `gUSDT` often requires bridging and extra fees.
GASSSS adds a gas sponsorship layer so users can execute transactions while paying a fixed fee in `STABLE`.
