STON.fi has introduced an Automated Market Maker (AMM) on the TON Blockchain and subsequently developed Omniston to consolidate liquidity across various decentralized exchanges (DEXs) on the platform. According to NS3.AI, this initiative aims to tackle liquidity fragmentation issues. However, Omniston encountered scaling challenges, particularly with multi-hop swaps, liquidity fragmentation, and the intricate behaviors of market participants. To address these issues, the team incorporated private liquidity sources through escrow swaps. They stress the importance of maintaining a fully non-custodial approach, prioritizing user education and a seamless experience. Looking ahead, STON.fi plans to expand into cross-chain aggregation to integrate liquidity beyond the TON ecosystem.
