Contract Architecture​

Core Components​

1. Settlement Contract​

The settlement contract handles:

  • Order matching and execution
  • Cross-chain message verification
  • Emergency pause functionality

2. Order Book Logic​

  • Limit order management
  • Order cancellation
  • Price-time priority matching
  • Slippage protection

Security Features​

Multi-Signature Control​

  • 3-of-5 multi-signature wallet for critical operations
  • Timelocked upgrades (48-hour delay)
  • Emergency pause functionality

Audited Code​

  • Smart contracts audited by leading security firms
  • Ongoing security monitoring
  • Bug bounty program active

Decentralized Governance​

  • Community governance for protocol upgrades
  • Transparent decision-making process
  • Token holder voting rights

Integration Guide​

For Developers​

Reading Contract State​

// BSC Contract
const bscContract = new ethers.Contract(
  '0x638C2ADdc76986E189fF98b8224a1d2B2d43a501',
  settlementABI,
  provider
);

// Base Contract
const baseContract = new ethers.Contract(
  '0x4333d6e8e1a617F71E3A6C3fB0f77aa4e6097F5A',
  settlementABI,
  provider
);

Placing Orders​

// Example limit order
const order = {
  tokenIn: '0x...',
  tokenOut: '0x...',
  amountIn: ethers.parseEther('1'),
  amountOutMin: ethers.parseEther('1800'),
  deadline: Math.floor(Date.now() / 1000) + 3600,
  recipient: userAddress
};

await contract.placeLimitOrder(order);
