Lombard Acquires BTC.b from Ava Labs in First-of-Its-Kind Deal
For 17 years, institutions could have either the security of top custodians or onchain utility—never both. Bitcoin Smart Accounts change that. They recognize custodial Bitcoin as collateral, transforming Bitcoin from a passive asset into usable onchain capital without asset movement, bridge risk, or exiting custody.
Bitcoin Smart Accounts are the first rail between institutional custody and onchain finance.

Bitcoin Smart Accounts rely upon foundational technologies
Partially Signed Bitcoin Transactions, Taproot scripts and time locks form emulated covenants.
Custodians participate in the validation of Bitcoin locks through a Trusted Execution Environment based arbitration system.
EVM based smart contracts enabling DeFi platform connectivity.
A decentralized network of 15 institutions has securely validated $5billion BTC transactions over 18 months.
Who This Is For
See it in action
If a corporate treasury held BTC with a qualified custodian and sought liquidity against it, they had three unattractive options:
1. Exit custody — Lose institutional insurance and introduce bridge and smart contract risk.
2. Use an OTC lender — Borrow at 8-12%, accept opaque terms and hidden spreads.
3. Sell Bitcoin — Triggering a tax event and lose upside potential.
A corporate treasury holding BTC can now deploy those assets onchain to earn yield, borrow stablecoins, and much more.
1. Remain in custody — BTC remains in the existing custody set-up (self-custody wallet, MPC, qualified custodian) maintaining the same security and protections.
2. Use onchain lenders — Borrow at 4-5%, adjust collateral and repay at any time without any third party approval.
3. Maintain BTC balance — Avoid selling Bitcoin and triggering tax events, and maintain exposure to upside potential.
Bitcoin Smart Accounts are live in pilot with select private clients. Public availability: Q1 2026.
