BounceBit is a blockchain platform operating as a Layer 1 Proof-of-Stake (PoS) network, designed to integrate Bitcoin (BTC) into a dual-token staking system. It uses both BTC and its native token, $BB, to secure the network, offering full compatibility with the Ethereum Virtual Machine (EVM). The platform combines elements of centralized finance (CeFi) and decentralized finance (DeFi), termed CeDeFi, by leveraging regulated custody solutions from partners like Mainnet Digital and Ceffu. Users can deposit BTC variants (e.g., native BTC, BTCB, WBTC) to earn yields through staking, restaking, and on-chain activities like farming. BounceBit introduces Liquidity Custody Tokens (LCTs) to maintain asset liquidity while generating returns. It also features a BTC bridge for cross-chain transfers, an app store for decentralized applications, and tools like BounceBox, aiming to connect Bitcoin’s security with broader blockchain ecosystems.
