Bitcoin, designed to integrate anywhere.
BTC.b is the onchain Bitcoin asset. It's 1:1 backed, and secured by a decentralized Security Consortium.
Neutral. Permissionless. Market-beating fees.
Neutral Bitcoin
BTC.b has no commercial alignment to any exchange, chain, or custodian. A centralized exchange, a DeFi protocol, and a neobank can all integrate simultaneously, and each adoption makes the asset more useful to the others.
Permissionless Access
Minting BTC.b does not require KYC. Any BTC holder can mint onchain from any wallet, exchange, or custodian.
Market-beating fees
BTC.b is built as infrastructure, not a profit centre. Users bridge Bitcoin with no bridging fees. The mint fee is capped at ~$0.02. Redemptions cost 0 satoshis.
BTC.b was built for platforms that want to bring Bitcoin assets to their platforms, without becoming an asset issuer themselves.

BTC.b questions, answered.
- What is BTC.b?
- BTC.b is Bitcoin on EVM chains. Originally built by Ava Labs, acquired by Lombard in October 2025 and now secured by the same institutional infrastructure as LBTC: a 14-member Security Consortium, HSM-backed key management, and Chainlink Proof of Reserve verification. It carries no yield assumptions and no lock-up. It is simply Bitcoin, accessible everywhere.
- How is BTC.b different from LBTC?
- LBTC is yield-bearing. It earns Bitcoin-on-Bitcoin returns via a Bitwise-managed covered-call strategy. BTC.b is a neutral Bitcoin representation with no yield and no lock-up. BTC.b is designed for platforms that want complete flexibility to build their own products on top, without any yield or lock-up assumptions.
- How is BTC.b secured?
- BTC.b is secured by Lombard's 14-member Security Consortium, the same infrastructure protecting $3B+ in LBTC. BFT consensus, HSM-backed key management via CubeSigner, and real-time Chainlink Proof of Reserve. 10+ audits. Zero incidents.
- What are the two integration options?
- Most platforms integrate BTC.b via the Lombard SDK, a single TypeScript integration giving users access to BTC.b alongside LBTC and Bitcoin Earn. For blockchains that want BTC.b as their native Bitcoin asset, a direct whitelabel integration is available, as MegaETH and Katana have done.
- Is there a lock-up period?
- No. BTC.b has no lock-up, no yield assumption, and no fee. It is a clean 1:1 Bitcoin representation. Holders can bridge back to native BTC at any time.
