Sign-In with Ethereum PHP
=========================

[](#sign-in-with-ethereum-php)

This package provides a PHP implementation of EIP-4361: Sign In With Ethereum.

Installation
------------

[](#installation)

```
composer require zbkm/siwe
```

Usage
-----

[](#usage)

1. The wallet is connected to the client, then the wallet address is sent to the server
2. On the server we generate SIWE messages.

```
$params = new SiweMessageParams(
    address: $address,
    chainId: 1,
    domain: "example.com",
    uri: "https://example.com/path"
);
```

or with params builder:

```
$params = SiweMessageParamsBuilder::create()
            ->withAddress($address)
            ->withChainId(1)
            ->withDomain("example.com")
            ->withUri("https://example.com/path")->build();
```

And we generate the message text:

```
$message = SiweMessage::create($params);
```

3. On the client side, we sign the SIWE message via personal\_sign. We send the received signature to the server.
4. All that remains is to check the signature.

```
if (SiweMessage::verify($params, $signature)) {
    // authorization success
} else {
    // authorization failed (signature invalid)
}
```

You can also look at a fully working [example](example) of authorization using the library.
