BounceBit is building BTC re-pledge infrastructure, providing a base layer for different re-pledge products, secured by Mainnet Digital and Ceffu’s custodial custody. Designed as a showcase for re-pledge products in the BounceBit ecosystem, BounceBit Chain is a PoS layer 1 secured by validators staking BTC and BounceBit’s native token — a two-token system that leverages native Bitcoin security and is fully EVM-compatible. Critical ecosystem infrastructure such as cross-chain bridges and oracles are secured by re-pledged BTC. Through an innovative CeFi + DeFi framework, BounceBit enables BTC holders to earn yield across multiple networks.
