decodeccopret

decodeccopret scriptPubKey

The decodeccopret method decodes the OP RETURN data from a CC transaction to output the EVALCODE and function id of the method that produced the transaction.

Finding the OP RETURN Data From a CC Transaction

The OP RETURN data from a CC transaction can be found by following these steps:

  • Decode a transaction produced by a CC module using the method getrawtransaction's verbose option.

  • Look for the vout key; it is an array of jsons

  • Find the json that contains the scriptPubkey, and which has the type:nulldata key pair

  • Copy the hex value from that scriptPubkey json

  • This is the hex-string that is expected as the argument for the above method.

  • You can verify that the transaction was produced by a CC module by checking if one of the vout json's scriptPubkey json has the type:cryptocondition key pair

Arguments
