I choose bitcoinj as java library and i would like to create the transaction on the watching wallet's application, send it serialized in an hexadecimal string to the privat wallet's application, in order to be signed by it, here the code i use for the serialization of the transaction: String hexTx = DatatypeConverter.printHexBinary(tx.bitcoinSerialize()); The problem is that i can't sign the transaction i deserialized from the string, here the code i use for deserilize the string and for sign the retured transaction: byte[] serializedTx = hexStringToByteArray(hexTx); Transaction deserializedTx = new Transaction(params,serializedTx); log...
