The coinbase transaction contains a single input, which has txid set to 0000000000000000000000000000000000000000000000000000000000000000 and vout set to 0xFFFFFFFF.

  • with this values, I got a Parse error as response. the json string I using is: {"jsonrpc": "1.0", "id":"curltest", "method":"createrawtransaction", "params":[{"txid":"0000000000000000000000000000000000000000000000000000000000000000","vout":0xFFFFFFFF}]. I also try with "vout":"0xFFFFFFFF"

  • @KleberMota You cannot enter a hex number or string for vout. That is invalid JSON.
