STON.fi is a decentralized automated market maker (AMM) based on the TON blockchain that offers almost zero fees, low slippage, an extremely simple interface, and direct integration with the TON wallet.

STON.fi is a cross-chain exchange based on a request for quote (RFQ) that relies on hashed time-locked contracts (HTLCs) to atomically execute cross-chain swaps. This approach eliminates the need for additional trusted entities and provides a combination of deep liquidity and price stability typically associated with RFQ-based exchanges, as well as uncompromising security common in on-chain DEXs. Since the protocol makes no trust assumptions on participants, we define it as a zero-trust cross-chain DEX.

The platform provides a simple, secure and fast solution for exchanging native tokens between multiple blockchains without the need for bridges or wrappers. In addition, STON.fi will be seamlessly integrated into Telegram Messenger, enabling users to manage and trade assets directly in the messaging application.
