Superchain Bridge

The Superchain Bridge Agent enables secure cross-chain token transfers between Superchain networks using the SuperchainERC20 standard and SuperchainTokenBridge.

Features

Secure Token Bridging

• Implements ERC-7802 for cross-chain mint/burn functionality

• Uses SuperchainTokenBridge for secure message passing

• Supports all Superchain networks (OP Mainnet, Base, etc.)

• Real-time bridge status monitoring

Autonomous Bridge Operations

• Automated token approvals

• Transaction status tracking

• Gas optimization

• Error recovery and retries

Supported Networks

Currently supported Superchain networks:

• OP Mainnet (Chain ID: 10)

• OP Goerli (Chain ID: 420)

• Base (Chain ID: 8453)

• Base Goerli (Chain ID: 84531)

How It Works

Initiating Message (Source Chain)

// User initiates bridge transaction
await bridgeAgent.handleEvent('BRIDGE_TOKENS', {
  token: 'USDC',
  amount: '1000000', // 1 USDC (6 decimals)
  fromChainId: 10,   // OP Mainnet
  toChainId: 8453,   // Base
  recipient: '0x...'
});

Token Bridge Flow

• Tokens are burned on source chain

• Message is relayed through L2ToL2CrossDomainMessenger

• Tokens are minted on destination chain

• Real-time status updates via events

Status Monitoring

// Check bridge transaction status
await bridgeAgent.handleEvent('CHECK_BRIDGE_STATUS', {
  txHash: '0x...',
  fromChainId: 10,
  toChainId: 8453
});

Security Features
