Sophon Account via EIP6963

Implementation of the EIP-6963 standard (Multi Injected Provider Discovery) for Sophon wallet. This enables applications to discover the Sophon wallet alongside other wallets in a standardized way.

Motivation

The Sophon SDK addresses several key challenges in blockchain application development:

1. Seamless Wallet Integration: Provides a standardized way to integrate with Sophon wallet without complex configuration
2. EIP Standards Compliance: Follows Ethereum Improvement Proposals (EIPs) to ensure compatibility with the ecosystem
3. Multi-Wallet Support: Implements EIP-6963 for better multi-wallet discovery and interaction
4. Developer Experience: Simplifies the wallet connection process to let developers focus on building their applications

Getting Started

Prerequisites

• Node.js (v14+)
• npm or yarn

Installation

To integrate the Sophon wallet with EIP-6963 support in your project:

# Using npm
npm install @sophon-labs/eip6963

# Using yarn
yarn add @sophon-labs/eip6963

Using the EIP-6963 Package

EIP-6963 is a standard that allows multiple Ethereum wallet providers to be discovered on a web page without conflicting with each other, unlike the traditional window.ethereum approach.

Basic Integration

1. Import and initialize the EIP-6963 emitter in your application entry point:

import "@sophon-labs/eip6963/testnet";

// The Sophon wallet will now announce itself via the EIP-6963 protocol
// No additional setup is required

This will automatically:

• Register the Sophon wallet provider
• Announce it through the EIP-6963 events
• Make it available to EIP-6963 compatible applications

Working with Wallet Connection Libraries

Most modern wallet connection libraries, like RainbowKit, wagmi, or Reown Appkit, support EIP-6963. Here's how to connect with wagmi:

import { getDefaultConfig } from "@rainbow-me/rainbowkit";
import { sophonTestnet, sophon } from "wagmi/chains";
import "@sophon-labs/eip6963/testnet"; // Import to announce the Sophon provider

export const config = getDefaultConfig({
  appName: "Your Application",
  projectId: "YOUR_PROJECT_ID",
  chains: [sophon, sophonTestnet],
  ssr: true,
});

With this setup, the Sophon wallet will appear in the wallet selection UI provided by RainbowKit.

Technical Details

EIP-1193 Compliance

The Sophon wallet implements the Ethereum Provider JavaScript API (EIP-1193), which defines a standard interface for Ethereum providers. This ensures compatibility with existing tools and libraries in the Ethereum ecosystem.

EIP-6963 Implementation

The @sophon/eip6963 package implements the Multi Injected Provider Discovery specification, which:

1. Announces the Sophon wallet provider through window events
2. Provides wallet metadata (name, icon, RDNS identifier)
3. Returns a compliant EIP-1193 provider interface
4. Responds to provider discovery requests

Examples

See the examples/eip6963-rainbow-wagmi and examples/eip6963-appkit directories for a complete example of integrating the Sophon wallet with RainbowKit and wagmi or AppKit.
