Return the raw transaction data. By default this function only works for mempool transactions. When called with a blockhash argument, getrawtransaction will return the transaction if the specified block is available and the transaction is found in that block. When called without a blockhash argument, getrawtransaction will return the transaction if it is in the mempool, or if -txindex is enabled and the transaction is in a block in the blockchain. Hint: Use gettransaction for wallet transactions. If verbose is true, returns an Object with information about txid. If verbose is false or omitted, returns a string that is serialized, hex-encoded data for txid.
