const ExceedBlockGasLimitError = "out of gas in location: block gas meter; gasWanted:"

ExceedBlockGasLimitError defines the error message when tx execution exceeds the block gas limit. The tx fee is deducted in ante handler, so it shouldn't be ignored in JSON-RPC API.

}

OverrideAccount indicates the overriding fields of account during the execution of a message call. Note, state and stateDiff can't be specified at the same time. If state is set, message execution will only use the data in the given state. Otherwise if statDiff is set, all diff will be applied first and then execute the call message.
