Wavey, a smart contract engineer known for treasury and security tooling, has open sourced safesmith, a command‑line wrapper around Foundry designed to streamline how teams create and queue Safe (formerly Gnosis Safe) multisig transactions via Solidity scripts. Safe is the dominant Ethereum multisig smart wallet used by DAOs, protocols and institutions to manage onchain treasuries, typically requiring multiple owner signatures before a transaction can execute. Many teams already use Foundry for scripting and testing contract interactions, and safesmith builds on that workflow so that the same Solidity scripts used in development can be used to prepare and queue production multisig actions. According to the public repository, safesmith sits on top of Angle Protocol’s earlier safe-multisig Foundry utilities, which allow contributors to script, test and then push bundled Safe transactions (such as parameter changes or treasury movements) while keeping full EVM‑level control and reproducibility. By wrapping these capabilities into a focused CLI, safesmith aims to reduce manual interaction with the Safe web UI, lower the risk of operator error, and make complex, multi‑step governance or treasury operations easier to version‑control and audit in code. This matters for DAOs, protocols and funds that rely on Safe multisigs for critical asset management, as it further formalizes “infrastructure as code” practices around onchain operations and can improve both security and operational efficiency in multisig governance.
