starknet_simulateTransactions RPC Method

Please note that some of the transactions may revert, in which case no error is thrown, but revert details can be seen on the returned trace object. Additionally, the revert_error property in the trace will indicate any transactions that have experienced a revert. Other types of failures (e.g. unexpected error or failure in the validation phase) will result in TRANSACTION_EXECUTION_ERROR.
