Uniswap Labs announced Seatbelt in collaboration with ScopeLift as a test suite for governance proposals.
The stated purpose is to strengthen DAO governance by generating proposal reports before votes so delegates and tokenholders have critical information for decision-making.
The launch checks listed were: referenced addresses touched by execution, contract-verification status, and state changes plus events resulting from execution.
The post said Seatbelt would check Ethereum for new proposals on a recurring cadence and publish reports in GitHub for public review.
Uniswap framed the project as reusable for any DAO using Governor Bravo, not only Uniswap.
Public README
The repo describes Seatbelt as tools that make on-chain governance safer, including automated scripts that apply checks to live proposals for better informed voting.
Reports are generated every few hours by workflow runs that simulate proposals for configured DAOs.
The README says reports note transaction reverts and summarize state changes and events, while omitting some execution-process noise to reduce report clutter.
Supported governors are listed as Compound Governor Bravo and OpenZeppelin-style governors.
Local usage depends on RPC, Tenderly, and optional Etherscan-backed analysis setup.
Why it matters to the corpus
Seatbelt is a governance control-surface project: it changes pre-vote visibility rather than vote weighting.
It is a strong comparison case next to Flexible Voting and Governance Emergency Rollback because those projects modify different points in the governance lifecycle: vote expression, proposal verification, and post-execution recovery.
