omni_createrawtx_opreturn

Adds a payload with class C (op-return) encoding to the transaction.

If no raw transaction is provided, a new transaction is created.

If the data encoding fails, then the transaction is not modified.

Arguments:

Name	Type	Presence	Description
`rawtx`	string	required	the raw transaction to extend (can be `null`)
`payload`	string	required	the hex-encoded payload to add

Result:

"rawtx"  // (string) the hex-encoded modified raw transaction

Example:

$ omnicore-cli "omni_createrawtx_opreturn" "01000000000000000000" "00000000000000020000000006dac2c0"
