BTC.b is a permissionless, non-yield Bitcoin asset native to the Avalanche ecosystem, designed to bring decentralized BTC liquidity to DeFi. Initially launched by Ava Labs in 2022 and now operated by Lombard Finance, BTC.b enables users to bridge Bitcoin on-chain and interact with Avalanche-based protocols like Aave, BENQI, and LFJ. With over $500 million in circulating supply, BTC.b serves as a neutral public good and complements Lombard’s yield-bearing LBTC.
