Address Book

Here you can find the address and associated ENS name (if available) for all of the World ID contracts. For verifying proofs, the only contract you need to interact with is the WorldIdRouter contract, which will properly route the call to the correct contract based on the groupId argument.

Only the Orb verification level is supported on-chain, so your groupId should always be 1.
