Built for Confidence.
Proven On-Chain.
Four independent layers of security. No single points of failure. Every satoshi secured and independently verifiable.
Four Layers. No Single Points of Failure.
Multiple parties must agree before any Bitcoin moves. Each transaction is independently verified, and every satoshi secured.
14 Institutions. No Unilateral Control.
An alliance of the industry's leading digital asset institutions, including Galaxy Digital, Wintermute, and Kraken. Members authorize every transaction, ensuring that no single entity can move funds alone. 10-of-14 consensus is always enforced.
Private Keys That Never Leave Hardware.
All signing operations are conducted inside FIPS-140 certified HSMs and Trusted Execution Environments. Even fully compromised servers cannot access the underlying keys.
Independent Verification Of Every Transaction.
All operational actions are verified by a second independent system. Bascule Drawbridge, by Cubist, verifies every deposit and redemption. Chainlink verifies every bridge transaction. Layered defense blocks unbacked issuance.
Enforced Rules. Active Defense.
Onchain timelocks for protocol upgrades provide additional review time. Real-time anomaly detection within the mempool can detect potential malicious actions before they happen, and pause the protocol.
14 Industry Leading Institutions.
Fourteen independent digital asset institutions collectively validate every mint, redemption, and cross-chain transfer. No single member can act alone, even nine compromised members cannot authorize a transaction.
Examine the Architecture.
Under the Hood.
Showing the Mint transaction flow.
Deposit. Consensus. Mint.
Deposit
Your BTC deposit is monitored independently and relayed to all involved parties. After six confirmations, cryptographic attestations are produced.
Consensus
A supermajority of Security Consortium members must sign to authorize any action. Keys are protected inside hardware enclaves. No member can ever access the raw private keys.
Mint
Minting requires valid signatures from both the Security Consortium and Bascule Drawbridge independently. Proof of Reserve oracles attest full Bitcoin backing on-chain.
Security You Can Verify and Trust.
No single entity can act alone
Every operation requires 10-of-14 independent institutions to reach consensus before a single satoshi moves. Lombard is one actor, not the operator. Nine compromised members still cannot authorize any transaction.
Enforced verification
Deposit validation, consensus checks, and Bascule Drawbridge attestation all execute before tokenized assets are issued. There is no window where minted tokens exist without fully backed Bitcoin. The system prevents discrepancies by design rather than detecting them after the fact.
Every layer provides independent security
CubeSigner, Bascule, the Security Consortium, and onchain Proof of Reserves each operate as if they are the last line of defense. Defense-in-depth in practice: independent systems, each alone sufficient to secure the protocol.
Enhanced governance and leading security practices
10+ audits from the top blockchain and cryptography experts. Real-time monitoring and threat detection. Protocol governance with two-step upgrades and timelocks. A $250,000 bug bounty keeps accountability continuous.
Verified by Experts.
Transparent to Everyone.
Verified by 10+ Independent Firms
OpenZeppelin, Veridise, Sherlock, Halborn, Spearbit, Cantina and more. Over ten independent firms have audited Lombard's smart contracts and architecture. Every report is publicly accessible.
