🔒 DecaFlow Privacy SDK

MEV Protection for Your Protocol in 5 Minutes

Open-source SDK for integrating MEV protection into DeFi protocols. Multi-language support. Free forever.

🚀 Quick Start

TypeScript/JavaScript

npm install @decaflow/privacy-sdk
# or
yarn add @decaflow/privacy-sdk

import { DecaFlowSDK } from '@decaflow/privacy-sdk';

const sdk = new DecaFlowSDK({ apiKey: 'your_key' });

const quote = await sdk.getPrivacySwapQuote({
  tokenIn: '0x...',
  tokenOut: '0x...',
  amount: '1000000000000000000'
});

await sdk.executePrivacySwap(quote);

Python

pip install decaflow-sdk

from decaflow import DecaFlowClient

client = DecaFlowClient(api_key="your_key")

quote = client.get_privacy_swap_quote(
    token_in="0x...",
    token_out="0x...",
    amount="1000000000000000000"
)

client.execute_privacy_swap(quote)

Solidity

import "@decaflow/contracts/interfaces/IPrivacyRouter.sol";

contract YourProtocol {
    IPrivacyRouter private router;
    
    function swap(address tokenIn, address tokenOut, uint256 amount) external {
        router.privacySwap(tokenIn, tokenOut, amount, msg.sender);
    }
}

💡 Examples

React Hook

import { usePrivacySwap } from '@decaflow/react';

function SwapComponent() {
  const { quote, execute, loading } = usePrivacySwap({
    tokenIn: WETH_ADDRESS,
    tokenOut: USDC_ADDRESS,
    amount: '1000000000000000000'
  });

  return (
    <button onClick={execute} disabled={loading}>
      Swap with MEV Protection
    </button>
  );
}

Custom Risk Threshold

const sdk = new DecaFlowSDK({ 
  apiKey: 'your_key',
  riskThreshold: 'high' // 'low', 'medium', 'high'
});

const quote = await sdk.getPrivacySwapQuote({
  tokenIn: WETH_ADDRESS,
  tokenOut: USDC_ADDRESS,
  amount: '1000000000000000000',
  slippageBps: 50 // 0.5%
});

console.log(`MEV Risk Score: ${quote.mevRiskScore}/100`);
console.log(`Estimated MEV Savings: $${quote.estimatedSavings}`);

Batch Transactions

const quotes = await sdk.getBatchPrivacySwapQuotes([
  { tokenIn: WETH, tokenOut: USDC, amount: '1000000000' },
  { tokenIn: USDC, tokenOut: DAI, amount: '1000000000' }
]);

await sdk.executeBatchPrivacySwaps(quotes);
