Message Sign Companion Guide

Usage of Zano Extension message sign.

  1. In your web app, call extension sign method, while extension is on.

Use zano_web3 lib SDK to make a request.

Request​

import { ZanoWallet } from 'zano_web3/web';

const zanoWallet = new ZanoWallet();

const message = "";

const response = await zanoWallet.requestMessageSign(
	message, 
	{
		timeoutMs: 60_000
	}
);

where:

  • message - Any message you want to sign (it could be one-time text (nonce) that is used for wallet sign)
  • timeoutMs - Timeout of request in ms (no timeout if not set)

Response​

{
	"success": true,
	"data": {
		"pkey": "",
		"sig": ""
	}
}

where:

  • pkey - Wallet's public key represented as a hexadecimal string
  • sig - Signature represented as a hexadecimal string

  1. As the result of method call, get signature and public key.

  2. Validate signature with validate_signature daemon method (either pkey or alias can be passed to daemon method alternatively). validate_signature method description: https://docs.zano.org/docs/build/rpc-api/daemon-rpc-api/validate_signature. You might also need to use get_alias_by_address method: https://docs.zano.org/docs/build/rpc-api/daemon-rpc-api/get_alias_by_address.

NOTE: You can opt out of the zano_web3 SDK and call Zano Companion directly via window.zano.request.

Request​

window.zano.request('REQUEST_MESSAGE_SIGN', {message}, timeout);

where:

  • message - Any message you want to sign (it could be one-time text (nonce) that is used for wallet sign)
  • timeout - Timeout of request in ms (set to null to disable)

Response​

{
	"data": {
		"result": {
			"pkey": "",
			"sig": ""
		}
	}
}

where:

  • pkey - Wallet's public key represented as a hexadecimal string
  • sig - Signature represented as a hexadecimal string
