outputs | It is possible to add additional asset transfers together with a contract call by attaching additional outputs. This is a JSON object containing "to", "amount" and "assetId" with json types respectively string, number and string. If "to" is a script hash, it will be translated to a valid NEO address | JSON | { "to": "AKJrLM5Q…", "amount": 1, "assetId": "602c79718…" } |
