generate-message-tool

Generate message from a whole transaction. For securely signing CKB transactions we provide a tool to generate message from the whole transaction,so you can compare it with the message generated from felix. Please refer to github repo for more details.

How to Run

• Run a CKB Testnet node.
• Copy the transaction JSON code generated by felix into this repo (such as wholetx.json in this repo)
• Fill in the tx_hash in inputs from the whole transaction

wholetx.json:
    "inputs": [
      {
        "since": "0x0",
        "previous_output": {
          "tx_hash": "0xa3dbfc7b2089f4bd6141342e25f21b03bcdd13f2b8600384aca37625a3a8735e",
          "index": "0x1"
        }
      }
    ],

index.js:
const INPUT_TX_HASH = "0xa3dbfc7b2089f4bd6141342e25f21b03bcdd13f2b8600384aca37625a3a8735e";
