USE CASE

Crypto Exchanges

Secure hot wallets, process withdrawals at scale, and eliminate single points of failure. Built for high-volume trading platforms.

How Exchanges Use PROXY SHIELD

🔥 Hot Wallet Infrastructure

Process user withdrawals automatically with MPC signing. No private keys on your servers. Handle thousands of withdrawals per hour with sub-500ms signing.

❄️ Cold Storage with Programmable Access

Create multi-signature cold wallets requiring multiple team approvals. Use our API to enforce spending limits, time delays, and whitelist policies.

💼 OTC Desk Settlement

Large block trades need secure settlement. Sign high-value transactions with confidence knowing 13 out of 24 agents must agree.

🔄 Auto-Rebalancing

Move funds between hot/warm/cold wallets automatically based on balance thresholds. Our API integrates with your treasury management system.

Integration Example

Process a user withdrawal:

// User requests withdrawal
async function processWithdrawal(userId, amount, toAddress) {
  const shield = new ProxyShield({ apiKey: process.env.PROXY_API_KEY });

  // Get the hot wallet for this chain
  const hotWallet = await shield.wallets.get('hot-wallet-eth');

  // Sign the withdrawal transaction
  const signature = await shield.sign({
    walletId: hotWallet.id,
    to: toAddress,
    value: ethers.parseEther(amount),
    gasLimit: 21000
  });

  // Broadcast and record
  const txHash = await provider.sendTransaction(signature.signedTx);
  await db.withdrawals.update(userId, { txHash, status: 'completed' });
  
  return txHash;
}
