When Bitcoin is bridged, it is locked in secure custody controlled by Lombard's 15-entity Security Consortium (including OKX, Galaxy, DCG, Kraken, Wintermute, Figment, Kiln, Antpool, and F2Pool), and an equivalent ERC-20 token is minted on Avalanche. Each BTC.b token is fully backed 1:1 by Bitcoin, verified through real-time Proof of Reserves via Chainlink integration providing on-chain collateral verification for both LBTC and BTC.b.
The bridge features competitive fee economics with 0% minting fees and 0.1% redemption fees, significantly lower than WBTC's 0.25% each way. As of February 15, 2026, BTC.b maintains approximately $502 million market cap with Bitcoin trading at $69,740-$70,779 following the broader crypto market correction from January highs.
Active integrations span major Avalanche DeFi protocols including Aave V3 and Benqi (collectively representing 63% of Avalanche TVL), Trader Joe, and GMX, while Lombard's parallel LBTC yield-bearing token has expanded to Solana, Base, Sui, and BNB Chain with over $1.3 billion market cap.
