STON.fi is a cross-chain decentralized exchange (DEX) built on TON, utilizing Request For Quote (RFQ) and Hashed Timelock Contracts (HTLC) for secure, trustless swaps. Its zero-trust design ensures deep liquidity and price stability without relying on intermediaries.

The platform's token, GEMSTON, incentivizes user participation and can be staked, traded, or held. Future plans include cross-chain swaps with TON-TRON and EVM chains, DAO governance, and a Telegram Web app.
