Lombard: Bitcoin Capital Markets Onchain

BTC.b: Bitcoin Bridged Right

A next-generation BTC asset built for the multi-chain future. Permissionless, decentralized, and secured by 15 leading institutions—BTC.b delivers institutional-grade Bitcoin infrastructure without compromise.

Bitcoin Designed for DeFi

Permissionless Access — Unlike centralized wrapped Bitcoin products BTC.b is open to anyone, anywhere. No accounts, no approvals—just connect your BTC wallet to mint.

Truly Decentralized — BTC.b is secured by a consortium of 15 independent digital asset institutions, eliminating counterparty risk inherent in comparable assets.

Verifiably Backed — BTC.b uses Chainlink Proof of Reserve to provide real-time, verifiable onchain data—not quarterly PDFs from auditors.

Bitcoin, Bridged Right

Bridge native Bitcoin onchain, and unlocking access to the full DeFi ecosystem.

BTC.b transforms passive Bitcoin holdings into productive capital without sacrificing security or custody. Bridge once, access everything—from simple swaps to complex DeFi strategies. Your Bitcoin shouldn't sit idle. Make it work for you.

Your Bitcoin. Your control. No compromises.

Bitcoin for Everyone. No Gatekeepers.

BTC.b is truly permissionless. No KYC verification. No account approvals. No institutional relationships required.  Unlike centralized wrapped Bitcoin that forces users to KYC, and trust intermediaries who can freeze assets or deny access, BTC.b removes that trust requirement entirely.

Verifiably Backed

Every BTC.b token is backed 1:1 by native Bitcoin, with proof published onchain.  This is real-time, cryptographically verifiable proof that anyone can check at any time supported by Chainlink's Proof of Reserve and Cubist Bascule. When billions are at stake, dual-verification is everything.

Secured by leaders

15 Institutions. Zero Single Points of Failure

The Evolution of BTC.b

Lombard acquired BTC.b from Ava Labs in October 2025, in a first of its kind asset acquisition. BTC.b now operates exclusively on the same trusted architecture as LBTC.

The two complementary products: BTC.b and LBTC, provides users with the full spectrum of Bitcoin utility—permissionless non-yield exposure or productive yield generation.
