Quicksign: KIP-0015

Additional quicksign endpoint to the kadena-signing-api that allows wallets to show the user multiple transactions at once for signature approval.

https://github.com/kadena-io/KIPs/blob/jam/quicksign/kip-0015.md

QuickSign 'Command':

This API allows to sign multiple transactions at once and ask for a signature approval to the user.

QuickSign 'Request':

QuickSign request: If you want to do a quick sign, use the kda_requestQuickSign request:

window.kadena
  .request({
    method: 'kda_requestQuickSign',
    data: {
      networkId: 'mainnet01',
      commandSigDatas: [
        {
          sigs: [/** sigs */],
          cmd: JSON.stringify(cmd),
        },
		{
          sigs: [/** sigs */],
          cmd: JSON.stringify(cmd2),
        }
      ],
    },
  })

commandSigDatas is an array of CommandSigData objects. The schema for a CommandSigData object is:

//{
  "sigs": [Signer],
  "cmd": string
}

The "cmd" string represents a json-encoded payload type, specified here: https://api.chainweb.com/openapi/pact.html#tag/model-payload The Signer schema instead:

{
  "pubKey": string,
  "sig": string //optional; its omission represents a signature that has not yet been acquired
}

• The pubKey field is a lowercase base-16 encoded public key

• The sig element is either a lowercase base-16 encoded signature or a null value (representing a request for signature).

QuickSign 'Response':

In case of a success sign you'll get a success response from eckoWALLET in the quickSigndata array (one element for each requested signing command)

{
  status: 'success',
  quickSignData: [
    {
      commandSigData: {
        cmd: '{{ cmdString }}',
        sigs: [
          {
            pubKey: 'publicKey',
            sig: '{{ sig }}',
          },
          {
            pubKey: 'other publicKey',
            sig: null,
          },
        ],
      },
      outcome: {
        hash: '{{ hashString }}',
        result: 'success',
      },
    }
 ]
}

The signature will be added in the correct sig record that contains the public key of the eckoWALLET account. In case of any error, the response status will be fail

{
    "status": "fail",
    "error": "QuickSign fail: wallet public key not found"
}
