Locate the authorized validator manager for a converted Avalanche L1

An L1 can have a validator manager on a chain distinct from the one its validators secure. Calling an identically addressed contract on the wrong chain cannot update the intended validator set.

Read conversion data from the P-Chain

Send the request to /ext/bc/P with the subnet identifier used for the conversion. Record conversionID, managerChainID and managerAddress from the converted subnet response. For an EVM manager, interpret the manager address bytes according to that chain’s address format.

{"jsonrpc":"2.0","id":1,"method":"platform.getSubnet","params":{"subnetID":"SUBNET_ID"}}

Select the RPC and management contract together

For example, a deployment inventory may contain both a staging and production manager at the same EVM address. Match the Avalanche blockchain ID to managerChainID before inspecting code or sending management calls. A legacy permissioned subnet can return control keys and a threshold instead. Confirm the subnet is converted before treating manager fields as authoritative.
