Request a check

Your vault, checked at today's block and attested onchain.

Paste an ERC-4626 vault on Monad mainnet and pay a small testnet fee. Our worker forks the vault, runs 30 properties nobody wrote for themselves, and records the result on Monad testnet. You get the result, the attestation, a badge and an API. The fee is held in escrow and becomes ours only when the attestation lands.
