Background

1inch, the leading DeFi ecosystem, has been selected as the exclusive swap provider at launch for Ledger Multisig, deepening the collaboration between the two projects. By integrating the 1inch Swap API into its security-first multisig architecture, Ledger, the world leader in digital asset security for consumers and enterprises, enables secure, seamless treasury swaps with full clear signing.

Blind Signing: A Structural Weakness

Blind signing has long been a structural weakness in on-chain treasury management, where DAOs, funds, enterprises, and DeFi teams are often required to take unnecessary risk when approving transactions. The combination of Ledger Multisig and the 1inch Swap API overcomes this issue, allowing every swap to be reviewed in clear, human-readable form, bringing execution into the light and aligning it with established standards for governance and asset transfers.

Secure, Seamless Treasury Swaps

Through this integration, there is no need for blind signing, thanks to structured, readable data via EIP-712. Users can review full transaction details on-device. 1inch's Swap API provides Ledger Multisig users with verifiable swap routes, deep liquidity aggregation for competitive pricing, support for safe-compatible trades across multiple chains, and MEV-resistant execution paths.

Elevating Security Across the DeFi Ecosystem

Ledger is once again setting a new benchmark for security, this time for treasury operations. By pairing hardware-level assurance with a trusted execution layer, Ledger Multisig eliminates a major security blind spot in DeFi. Organizations can now manage assets, rebalance treasuries, and interact with DeFi with clarity, confidence, and uncompromising security.

In addition to bringing swaps to Ledger Multisig, 1inch is also adopting the signing technology to elevate its own security across its own treasury workflows. By utilizing Ledger Multisig, 1inch is creating and setting the standard for secure and seamless operations.
