Class ContractActionData

A single entry in the call graph of a historical contract transaction — one per nested EVM call (CALL, CREATE, DELEGATECALL, precompile invocation, etc.). Retrieved via GetContractActionsByTransactionHashAsync(MirrorRestClient, EvmHash, params IMirrorQueryParameter[]) and GetContractActionsByTransactionIdAsync(MirrorRestClient, TransactionId, params IMirrorQueryParameter[]).
