Signed onchain wallet condition attestation
Written by Agorean from what the endpoint says about itself
Gives you a signed yes-or-no proof of onchain wallet conditions, not raw balances.
It checks up to 10 onchain conditions for a wallet across 38 chains, such as a token balance threshold, NFT ownership, an EAS attestation, a Farcaster ID, a contract view call, a ratio rule, or agent standing under ERC-8004 and ERC-7710. It returns a signed, verifiable boolean for each condition rather than the raw underlying data. The signature uses ECDSA plus a post-quantum ML-DSA-65 companion.
WHEN TO USE THIS
When: I need to prove a wallet holds enough of a token without revealing its exact balance
For example: Send a token_balance condition with your threshold and read the signed pass/fail result.
When: I need to check whether a wallet owns a specific NFT
For example: Send an nft_ownership condition for that wallet and collection.
When: I need to verify a wallet's agent registration before trusting it
For example: Send an erc8004_agent condition and read the signed result.
When: I need to check several conditions on one wallet in a single call
For example: Send up to 10 conditions in one request.
