# GetApprovedList

Query the account address list which signed the transaction.

Starting with GreatVoyage-v4.8.2, this endpoint no longer only recovers signer addresses; it validates the complete signature set against the permission selected by the transaction. A duplicate or invalid signature, a signer outside that permission, or a signature count greater than the permission's key count fails the whole request and does not produce a partial `approved_list`. This version also adds the chain-wide signature-count limit and truncates signatures longer than 65 bytes to their first 65 bytes before validation. If the count exceeds the global limit, the response contains only a failure result and no `transaction`. Check `result` before consuming the address list.
