EVM signature request decoder
Written by Agorean from what the endpoint says about itself
Decodes what you are actually about to sign in an EVM signature request.
Give it an EVM signature request, such as EIP-712 typed data, a Permit or Permit2, or ERC-20 approve calldata, and it decodes it into a structured intent. It returns which token, which spender, how much, and until when, plus risk flags and an action hint. It runs deterministically with no LLM, for an agent that needs to answer what it is about to sign before it signs.
WHEN TO USE THIS
When: I am about to sign a token approval and need to know what I am authorizing
For example: Send the signature request to see the token, spender, amount, and expiry it decodes to.
When: I need to know if a signature request looks risky before I sign it
For example: Check the risk_flags returned for the decoded request.
When: I need a quick recommendation on whether to proceed with a signature
For example: Read the action_hint included in the decoded response.
