STON.fi is a non-custodial AMM protocol on TON. It lets you swap tokens, provide liquidity, farm rewards, stake STON, and take part in protocol governance — directly from your own wallet, without transferring your funds to any custodian.
What makes STON.fi different
- Non-custodial. Your funds stay in your wallet until you confirm a transaction. There's no account and no central party holding your tokens — DeFi-native access.
- Built for TON. Running on TON means very low fees and near-instant settlement. The actual blockchain fee for a typical swap is around 0.02 Gram (formerly Toncoin), with a small additional amount reserved at swap time and refunded if unused.
- Smart contracts audited. Contracts are public and have been audited — see the security audit article for the latest report.
- DAO-governed. STON token holders can stake to receive voting power and shape the protocol's future through proposals.
