STON.fi DEX overview - decentralized exchange with AMM pools, liquidity provision, and yield farming on TON

STON.fi DEX is a decentralized exchange protocol that enables permissionless token swaps and liquidity provision on the TON blockchain.

Core Features

Token Swaps

• Direct token-to-token exchanges using liquidity pools
