List a key

Paste an OpenRouter key with credit on it.

Set a credit limit on the key at openrouter.ai/settings/keys first: that limit is what Colossus can verify and sell. When you list it, the key is sealed in your browser to the operator’s public key, and only the sealed copy goes on chain.

Connect the wallet that gets paid.

Wallet only. The key attaches to that address, and your USDG lands there.

Nothing is signed until you list.
