According to the latest data, the total value locked (TVL) of the BTC interchain protocol, Free Protocol, has exceeded $1 billion, making it stand out in the market. Unlike its competitors, Free Protocol demonstrates a wider array of applications, including support for popular tokens such as M-BTC and SolvBTC, as well as well-known blockchain platforms like Merlin and Core. Its key feature is the provision of direct cross-chain services without the necessity of asset bundling, middle chains, or liquidity pools, markedly streamlining the exchange of Bitcoin-related assets across various chains and boosting liquidity. Through facilitating the supply of homogenous tokens across multiple chains, Free Protocol contributes to the overall enhancement of liquidity within the DeFi ecosystem.
