Babylon Labs and hardware wallet leader Ledger announced a partnership on March 10, 2026 to bring trustless Bitcoin Vaults (BTCVaults) to millions of self-custody users worldwide. The integration leverages Ledger’s Clear Signing technology, enabling users to verify and authorize vault transactions directly on their Ledger devices, ensuring bitcoin remains on its native blockchain without third-party intermediaries.
Clear Signing: Transparency and Security
Ledger has sold over 8 million hardware signers, establishing a secure signing layer for decentralized finance (DeFi). Clear Signing ensures every transaction detail is displayed on the device, preventing malicious tampering. “Integrating Clear Signing with Ledger, together with Ledger Wallet connectivity, makes that model practical for millions of self-custody users,” said David Tse, Co-Founder of Babylon.
$15M Funding to Expand Bitcoin Lending
Babylon Labs previously secured $15 million in funding from A16z Crypto to develop trustless bitcoin lending protocols. The partnership with Ledger expands its ecosystem: users can manage Bitcoin Vaults and access Babylon’s bitcoin staking services. Supported assets include native Bitcoin (BTC) and Babylon’s native token BABY. Future plans include full integration of Bitcoin staking within the Ledger ecosystem.
Industry Impact
This integration marks a milestone for Bitcoin DeFi (BTCFi). Combining hardware wallet security with trustless vaults lowers the barrier for users to participate in lending, staking, and other financial activities. Babylon Labs aims to enable bitcoin holders to earn yields without relinquishing self-custody. With Ledger’s massive user base (8M+ devices), the distribution channel directly supports broader adoption of BTCFi.
