Filament Web3 Auth

A Filament v4 plugin for Web3 wallet authentication (MetaMask, and other EIP-1193 compatible wallets).

Features

• Login with crypto wallet (MetaMask, etc.)
• Auto-register new users on first wallet login
• Link/unlink wallet to existing accounts
• Multi-network token dashboard (Ethereum, Polygon, Arbitrum, Base, Sepolia)
• Fully customizable and translatable

Installation

Install the package via Composer:

composer require geof-dev/filament-web3-auth

Publish and run the migration:

php artisan vendor:publish --tag="filament-web3-auth-migrations"
php artisan migrate

Optionally publish the config file:

php artisan vendor:publish --tag="filament-web3-auth-config"

Optionally publish the views:

php artisan vendor:publish --tag="filament-web3-auth-views"

Add the plugin's views to your Filament theme CSS file (e.g., resources/css/filament/admin/theme.css):

@source '../../../../vendor/geof-dev/filament-web3-auth/resources/views/**/*.blade.php';

Then rebuild your assets:

npm run build

Usage

Register the plugin in your Filament panel provider:

use GeofDev\FilamentWeb3Auth\FilamentWeb3AuthPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugin(
            FilamentWeb3AuthPlugin::make()
                ->autoRegister(true)      // Auto-create users on first login
                ->showOnLogin(true)       // Show button on login page
        );
}

Plugin Options

Configuration

// config/filament-web3-auth.php

return [
    'enabled' => env('FILAMENT_WEB3_AUTH_ENABLED', true),
    'auto_register' => env('FILAMENT_WEB3_AUTH_AUTO_REGISTER', true),
    'signature_message' => 'Sign this message to authenticate with :app_name. Nonce: :nonce',
    'user_model' => null, // Uses default auth model
    'route_prefix' => 'web3-auth',
    'middleware' => ['web'],
    'auth_middleware' => ['web', 'auth'],
];

User Model Setup

Ensure your User model has the eth_address column fillable:

protected $fillable = [
    'name',
    'email',
    'password',
    'eth_address',
];

Adding Wallet Manager to Profile

The easiest way is to use the plugin's EditProfile page in your panel:

use GeofDev\FilamentWeb3Auth\Pages\Auth\EditProfile;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->profile(EditProfile::class);
}

Or add the component manually to your custom profile page:

use Filament\Schemas\Components\View;

View::make('filament-web3-auth::components.wallet-manager')
