$ cast wallet sign --help

用法：cast wallet sign [OPTIONS] <MESSAGE>

参数：
  <MESSAGE>
          The message, typed data, or hash to sign.
          
          Messages starting with 0x are expected to be hex encoded, which get
          decoded before being signed.
          
          The message will be prefixed with the Ethereum Signed Message header
          and hashed before signing, unless `--no-hash` is provided.
          
          Typed data can be provided as a json string or a file name. Use --data
          flag to denote the message is a string of typed data. Use --data
          --from-file to denote the message is a file name containing typed
          data. The data will be combined and hashed using the EIP712
          specification before signing. The data should be formatted as JSON.

选项：
      --data
          Treat the message as JSON typed data

      --from-file
          Treat the message as a file containing JSON typed data. Requires
          `--data`

      --no-hash
          Treat the message as a raw 32-byte hash and sign it directly without
          hashing it again

  -h, --help
