About STON.fi
STON.fi is a decentralized exchange on TON that now describes itself as a cross-chain interface: swap between TON, EVM networks and TRON from one place without sending assets through a separate bridge first. The site stresses that it is self-custodial, so the swap is signed from your own wallet.
Its routing layer is called Omniston. The page says swaps are atomic, meaning a trade either completes in full or is refunded in full, and that the route, the fees and the expected output are shown before you confirm. The app also has pools and staking sections.
