Timelock Model for Secure On‑Chain Multisig – Ethereum Foundation

The Ethereum Foundation presentation explains how separating clearing and settlement, a practice from traditional finance, can improve security for on‑chain multisig wallets. It proposes using timelocks as a clearing layer to allow reversibility when a multisig signer is compromised. The speaker, Elliot Friedman, shares lessons from building a timelock‑based self‑custody system on top of Gnosis Safe, outlines operational changes required for multisig teams, and highlights challenges such as MEV and transaction visibility. The talk also shows how to integrate timelock modules with existing Safe deployments, and all code is open source.
