This table is maintained against the registry itself, and a test in the backend fails
the build if a chain here disagrees with it. The machine-readable version is
GET /api/chains, which is generated from the same source.What “deployed” means for identity
The ERC-8004 registries are not ours. Their authors deployed them deterministically, so the same addresses appear on chain after chain, and where they were already present we simply read them. Where a piece was missing we reproduced it by replaying the canonical deployment calldata rather than forking a new contract, which is why the addresses still match everywhere. Two consequences worth stating plainly, because they are easy to get wrong:- A chain can carry an IdentityRegistry and no ValidationRegistry. On those chains a KYA result cannot be anchored on-chain. It is still verified and recorded, and we say so rather than reporting a zero that reads like a real count.
- A chain can have a real settlement token and no canonical Circle USDC. Robinhood Chain is exactly that: the registry’s USDC slot stays empty on purpose, and USDG is named as its own thing, because every generic USDC code path reads that slot.
