USE CASE

DeFi Protocols

Secure your DAO treasury, yield aggregator, or DEX smart contracts with enterprise-grade MPC signing. No single point of failure.

How DeFi Protocols Use PROXY SHIELD

🏛️ DAO Treasury Management

Store multisig treasury funds with 13-of-24 threshold signing. No single keyholder can drain the treasury. Integrate with Gnosis Safe or use directly via API.

📈 Yield Aggregator Hot Wallets

Automate yield farming with secure signing. Your bot calls our API for transaction signing—keys never touch your servers. Perfect for vault rebalancing.

🔄 DEX Liquidity Management

Manage LP positions programmatically. Sign add/remove liquidity transactions with sub-500ms latency. Handle high-volume operations during market volatility.

🔐 Protocol Admin Keys

Secure upgrade keys, pause functions, and governance actions. Key rotation ensures old shares become useless—even if a past keyholder is compromised.

Integration Example

Sign a Uniswap swap transaction:

// Initialize client
const shield = new ProxyShield({ apiKey: 'ps_live_xxx' });

// Create a wallet for your DAO treasury
const wallet = await shield.wallets.create({
  name: 'DAO Treasury',
  chain: 'ethereum'
});

// Sign a Uniswap swap transaction
const signature = await shield.sign({
  walletId: wallet.id,
  to: '0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D',  // Uniswap Router
  data: swapExactTokensForTokensData,
  value: '0',
  gasLimit: 300000
});

// Broadcast to Ethereum
const txHash = await provider.sendTransaction(signature.signedTx);
