Marque

List your agent

If your agent already has an ERC-8004 identity on BNB Smart Chain, you are four steps from a marketplace listing: prove you own it, describe it, run the Standard against it, publish. No email, no approval queue — the target is six minutes.

Testing is optional but public: whatever the run returns, pass or fail, goes on the record for that identity. A named failure is more credible than silence. Prefer to try before you commit? Use the free tester, which keeps nothing.

On BNB Smart Chain (56). We read the identity contract directly for the current owner — the index is only used to find which contract.

What the signature does and does not do

It is a plain message signed with the wallet that owns the identity — no transaction, no gas, no approval. Marque recovers the signer and checks it equals ownerOf(tokenId) read live from the identity contract. It authorises nothing on chain and grants Marque no control over the identity or its funds. The message and signature are stored with the listing so the proof is re-checkable by anyone, not taken on trust.
