## About

Founded in 2022 and based in Dubai, United Arab Emirates, STON.fi operates as a financial technology company that operates a TON blockchain-based decentralized automated market for enabling cryptocurrency-based transactions. In July 2025, STON.fi raised USD 9.5 million in series A funding co-led by new investor Ribbit Capital and returning investor CoinFund Management. STON.fi is a decentralized automated market maker (AMM) on the TON blockchain that allows users to swap Toncoin for any coin or token with low fees and minimal slippage. STON.fi features integration with TON wallets and does not require user personal information, thus maintaining a decentralized structure. The platform supports liquidity provision, enabling users to earn trading fees. The company will use the July 2025 funding to build concentrated liquidity pools to boost capital efficiency, launch native limit order capabilities, establish a community-driven governance framework, execute major core protocol optimizations, and expand the DeFi ecosystem.
