According to PANews, BounceBit, a Bitcoin collateral chain, announced on Twitter that it plans to launch its mainnet in April. Early contributors can now participate in a preview on the official website, where they can earn points based on their total value locked (TVL) and referred users. BounceBit went live on January 30th this year, and its current TVL has exceeded $450 million. The platform is a middleware protocol built on top of the Bitcoin asset class, introducing BTC re-collateralization.
