1inch Named Exclusive Swap Provider at Launch for Ledger Multisig

Road Town, British Virgin Islands, 11 December 2025, according to CyberNewsWire, 1inch has been selected as the exclusive swap provider at launch for Ledger Multisig. By integrating the 1inch Swap API into its security-first multisig architecture, Ledger enables secure, seamless treasury swaps with full clear signing, elevating on-chain treasury security for organisations.

Blind signing has long been a weakness in treasury management, and the integration of Ledger Multisig with 1inch Swap API provides verifiable, human-readable data via EIP-712 so transactions can be reviewed on-device. 1inch’s Swap API offers verifiable swap routes, deep liquidity aggregation for competitive pricing, support for safe-compatible trades across multiple chains, and MEV-resistant execution paths, according to the release.

Ledger notes that this collaboration sets a new benchmark for security in treasury operations, while 1inch will also extend Ledger Multisig signing technology to its own treasury workflows. The press also quotes Sergej Kunz and Sebastien Badault emphasising safer, simpler self-custody tooling for mature DeFi ecosystems.
