Odaily News According to official news, Ref Finance has undergone the latest upgrade and has become a DeFi hub that supports multi-chain asset liquidity, using NEAR's chain abstraction technology to provide users (especially Bitcoin holders) with a convenient way to access various financial services on a unified platform. This upgrade makes it possible for DeFi services to cover the neglected Bitcoin market, which is expected to unlock a market potential worth $45 billion, while demonstrating the rapid growth of Ref Finance and its core role in NEAR's DeFi ecosystem. It is reported that Ref Finance is a cutting-edge decentralized financial DApp based on the NEAR protocol. Since its establishment in 2021, it has transformed from a simple AMM to a comprehensive DeFi platform, with a total locked value (TVL) of more than US$50 million, accounting for 25% of NEAR TVL (now about US$198 million).
