BOB (Build on Bitcoin) has launched a Bitcoin Vault Liquidation Engine, allowing Bitcoin holders to secure stablecoin loans while maintaining their assets on the Bitcoin network. This new framework addresses challenges such as all-or-nothing liquidations and slow settlement processes by enabling partial liquidations and faster execution times. The initiative aims to unlock significant Bitcoin liquidity for decentralized finance (DeFi), expanding BTC-backed borrowing options beyond wrapped assets like wBTC. Other projects in the BTCFi space include Hemi and Babylon.
