oSnap has integrated Tenderly’s Simulator feature, allowing users to preview transactions before submitting proposals. Released in 2023, oSnap has quickly become popular in the DAO ecosystem, simplifying governance voting outcomes on-chain.

Its integration with Tenderly, a Web3 platform for testing solutions, enhances user experience. With oSnap, users can create transaction payloads in Snapshot, aiding DAOs like Connext and CoW Protocol in governance. However, the lack of transaction testing increased the risk of errors. Tenderly's integration introduces transaction simulation, improving accuracy.

This collaboration enhances oSnap's value proposition for DAOs, offering users visibility into essential transactions before finalizing them in Snapshot. oSnap, short for Optimistic Snapshot Execution, leverages UMA's optimistic oracle and Snapshot's gasless voting system, enabling DAOs to execute governance votes on-chain without trust. Governance-approved proposals are linked to UMA for on-chain implementation, with dissent resolved through $UMA token holder votes.

The solution has raised $500 million within a year, with OpenZeppelin auditing oSnap.
