Method hmyv2_estimateGas Harmony (ONE)
connect with JSON-RPC protocol

hmyv2_estimateGas

info-circle-fill

Returns an estimate of the gas required for a transaction to complete.The estimation process does not use gas and the transaction is not addedto the blockchain. The resulting estimate can be greater than the amountof gas the transaction ends up using, for reasons including EVMmechanics and node performance.The hmyv2_estimateGas call does not send a transaction. You must callhmyv2_sendRawTransaction to execute the transaction.If revert reason is enabled with --revert-reason-enabled, thehmyv2_estimateGas error response will include the revert reason.

Parameters

object - object

Transaction call object.
