Looking to write a call that could return all the contract addresses of ink contracts matching a code hash of the contract via RPC.

What would be the best way to go about getting the list of contract instances matching the hash?


  • What types of contracts? I presume ink using the contracts pallet or evm & frontier, but please update your question to be more explicit?

The pallet_contracts has the storage ContractInfoOf (see in the code) which is a mapping of the contract info (that includes the code hash) associated with a given account.

You can query all the elements stored here and get all the account Ids that matches your hash code.

An example of the query using PolkadotJS UI:
