BOB (“Build on Bitcoin”), the hybrid chain combining Bitcoin’s security with Ethereum’s DeFi innovation, has enabled native BTC on its network with a new BitVM bridge testnet launch supported by leading institutions and DeFi players, including P2P.org, Lombard, Solv Protocol, Amber Group, Ankr, RockawayX, Fiamma, UTXO Management, Luganodes & SatLayer. Following the testnet, the BitVM bridge and native BTC will go live on BOB mainnet in Q4 2025.
The launch solidifies BOB as the gateway to Bitcoin DeFi by making native BTC, not wrapped representations, available to their extensive Bitcoin DeFi ecosystem. Unlike other Bitcoin variants currently used in DeFi, which rely on centralized custodians or multisigs, BOB’s BitVM bridge uses fraud-proof “1-of-N” security to provide Bitcoin security guarantees. Just as ETH remains “ETH” on Ethereum rollups like Optimism and Arbitrum, BTC on BOB remains native and simply called “BTC.”
