the tool registry
Every ERC-8257 tool registered on RH-Chain, with its manifest re-fetched and re-hashed here against what the chain committed to. Alphabetical. Anyone may register — including people with nothing to do with Elo, whose entries are checked and reported exactly like ours.
An ERC-8257 entry commits a hash of the tool's manifest on chain. That commitment is only worth something if somebody actually re-fetches the manifest and re-computes the hash — otherwise the registry is a list of promises. This page runs that check on every entry and reports what it finds either way, including the entries that fail.
The registry contract is OpenSea's reference deployment (—), the same CREATE2 address on Ethereum, Base and RH-Chain. Elo does not run its own — a second registry would fragment the standard. Verification is a fact about bytes: this page reports what the hashes say, and nothing anyone pays can put a tool on it, move it, or take it off.

Anyone may register. The registry is permissionless, and so is this view of it.
- Serve a manifest at
/.well-known/ai-tool/<slug>.json. - Hash it:
keccak256(RFC-8785-JCS(manifest)). - From your own wallet, call
registerTool(uri, hash, address(0))on the registry — one transaction on RH-Chain.
Elo holds no key and cannot register on your behalf. The full recipe, with Elo's own manifests and their exact hashes, is published as JSON, and so is this page's own read of the registry. New to the chain? the add-chain params are posted too.
