=============

[](#web3signature)

Laravel Package for extracting addresses from web3 signed messages

Usage
=====

[](#usage)

Composer:

```
composer require desnake/web3signature

```

In view:

```
//prepare message to sign

const msgtext = {{$msg}};   //Message from backend database sent with view
const hashedMessage = Web3.utils.fromUtf8(msgtext);
console.log(hashedMessage);

//get user to sign the message

const signature = await window.web3.eth.sign(hashedMessage, accounts[0]);

//Make request to controller and verify signature in backend via API
//!!CAUTION!!
//Not much secure way to do this but only for demo purposes.

const URL = "api.myproject.com/api/v1/";
const request = URL + msgtext + "/" + signature;

window.location.href(request);

```

In controller:

1: Make a api route in such a way that a signature is passed to controller function 2: Import trait Web3ForContracts into the controller:

```
    use DeSnake\Web3signature\Web3ForContracts;
    and Include trait into the controller class.
    `` use Web3ForContracts;``

```

3: Call personal\_ecRecover function from controller:

```
Note: $msg is plaintext string that is signed and signature is the signed message
    $msg = "Hello World";   //Message from backend database.
    $address = $this->personal_ecRecover($msg, $signature);

```
