🌉 DeBridge Integration Task

📋 Overview

Integrate DeBridge cross-chain bridge into Purro Extension to enable simple token bridging between HyperEVM and other supported chains. DeBridge is chosen for its simplicity - single contract integration with straightforward API.

Reference: DeBridge Documentation

🎯 Objectives

Primary Goals

• ✅ Add "Bridge" tab to main interface
• ✅ Enable token bridging from HyperEVM to other chains
• ✅ Simple one-click bridge functionality
• ✅ Support major chains: Ethereum, Base, Arbitrum

Secondary Goals

• 🔄 Bridge status tracking
• 🔄 Bridge history
• 🔄 Gas fee estimation for bridge transactions

🏗️ Technical Architecture

DeBridge Contract Address (HyperEVM)

DeBridgeGate: 0x43de2d77bf8027e25dbd179b491e8d64f38398aa

Supported Chains

• HyperEVM (Chain ID: 999) - Source chain
• Ethereum (Chain ID: 1) - Destination
• Base (Chain ID: 8453) - Destination
• Arbitrum (Chain ID: 42161) - Destination

🧪 Testing Strategy

Unit Tests

# Test DeBridge service
pnpm run test:debridge

# Test bridge integration
pnpm run test:bridge

Integration Tests

• Test bridge from HyperEVM to Ethereum
• Test bridge from HyperEVM to Base

📋 Simple Implementation Steps

Step 1: Add DeBridge Contract

// src/constants/debridge-config.ts
export const DEBRIDGE_CONFIG = {
  contractAddress: '0x43de2d77bf8027e25dbd179b491e8d64f38398aa',
  supportedChains: {
    hyperevm: 999,
    ethereum: 1,
    base: 8453,
    arbitrum: 42161
  }
};

Step 2: Create Bridge Service

// src/client/services/debridge-service.ts
export class DeBridgeService {
  async estimateBridge(
    token: string,
    amount: string,
    fromChain: number,
    toChain: number
  ) {
    // Estimate bridge fees and time
  }

  async executeBridge(
    token: string,
    amount: string,
    fromChain: number,
    toChain: number,
    recipient: string
  ) {
    // Execute bridge transaction
  }
}

Step 3: Add Bridge Tab

// src/client/screens/main/main-screens/bridge/BridgeScreen.tsx
export const BridgeScreen = () => {
  return (
    <div>
      <ChainSelector />
      <TokenInput />
      <BridgeButton />
    </div>
  );
};

Note: This is a simple integration focusing on the easiest bridge protocol to implement. DeBridge provides a straightforward API with minimal configuration required.
