Overview

IXFI Protocol includes one of the most comprehensive DEX aggregation systems in DeFi, supporting 37+ protocols across 7 blockchain networks for optimal trading execution.

Why DEX Aggregation?

The Fragmentation Problem

Modern DeFi spans multiple chains and hundreds of DEX protocols, each with:

  • Different liquidity pools

  • Varying fee structures

  • Unique token pairs

  • Inconsistent pricing

Without aggregation, users face:

  • ❌ Manual comparison across multiple DEXes

  • ❌ Suboptimal pricing due to limited liquidity

  • ❌ High gas costs from multiple transactions

  • ❌ Complex cross-chain operations

With IXFI aggregation:

  • ✅ Automatic best price discovery

  • ✅ Single transaction execution

  • ✅ Cross-chain routing optimization

  • ✅ Unified interface across all protocols

Routing Algorithm

Multi-Hop Routing

IXFI's routing algorithm finds optimal paths across multiple protocols:

Route Optimization

Factors Considered:

  1. Price Impact - Slippage minimization

  2. Gas Costs - Transaction fee optimization

  3. Liquidity Depth - Available token reserves

  4. Protocol Fees - DEX-specific charges

  5. Split Routing - Distributing trades across multiple paths

Algorithm Steps:

  1. Quote Generation - Get prices from all 37 protocols

  2. Path Discovery - Find viable multi-hop routes

  3. Split Optimization - Determine optimal trade distribution

  4. Gas Estimation - Calculate execution costs

  5. Best Route Selection - Maximize net output

Smart Routing Features

Split Routing:

// Example: $10,000 USDC → WETH split across protocols
{
  "totalAmountIn": "10000000000", // 10,000 USDC
  "routes": [
    {
      "protocol": "Uniswap V3",
      "percentage": 45,
      "amountIn": "4500000000",
      "expectedOut": "1.234 ETH"
    },
    {
      "protocol": "SushiSwap V2", 
      "percentage": 35,
      "amountIn": "3500000000",
      "expectedOut": "0.956 ETH"
    },
    {
      "protocol": "Curve",
      "percentage": 20,
      "amountIn": "2000000000", 
      "expectedOut": "0.543 ETH"
    }
  ],
  "totalExpectedOut": "2.733 ETH",
  "priceImpact": "0.12%",
  "gasEstimate": "450000"
}

Quote System

Real-Time Price Discovery

The quote system provides instant price comparisons across all supported protocols:

Quote Sources:

  • On-chain calls to DEX contracts

  • Subgraph queries for historical data

  • Price oracles for validation

  • Mempool analysis for MEV protection

Quote Comparison

async function compareQuotes(tokenIn, tokenOut, amountIn) {
  const quotes = await aggregator.getAllQuotes(tokenIn, tokenOut, amountIn);
  
  return quotes.map(quote => ({
    protocol: getDEXName(quote.routerType),
    amountOut: quote.amountOut,
    priceImpact: calculatePriceImpact(quote),
    gasEstimate: quote.gasEstimate,
    netOutput: quote.amountOut.sub(quote.gasEstimate)
  })).sort((a, b) => b.netOutput.sub(a.netOutput));
}

Dynamic Updates

Quote Refresh Strategy:

  • Block-based updates for high-frequency pairs

  • Time-based refresh for standard pairs

  • Event-driven updates for liquidity changes

  • User-triggered refresh for manual updates

Cross-Chain Aggregation

Cross-Chain Swap Flow

Cross-Chain Route Optimization

Considerations:

  • Bridge costs and timing

  • Destination chain liquidity

  • Gas price differences

  • MEV protection across chains

Integration Examples

Basic Swap

import { CrossChainAggregator } from '@ixfi/sdk';

async function performAggregatedSwap() {
  const aggregator = new CrossChainAggregator({ network: 'mainnet' });
  
  // Get optimal route
  const quote = await aggregator.getOptimalQuote(
    '0xA0b86a33E6441e1a02c4e4670dd96EA0f25A632', // USDC
    '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2', // WETH
    ethers.utils.parseUnits('1000', 6) // 1000 USDC
  );
  
  console.log(`Best price: ${quote.bestAmount} WETH`);
  console.log(`From: ${quote.dexName}`);
  console.log(`Price impact: ${quote.priceImpact}%`);
  
  // Execute swap
  const tx = await aggregator.executeSwap({
    tokenIn: '0xA0b86a33E6441e1a02c4e4670dd96EA0f25A632',
    tokenOut: '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
    amountIn: ethers.utils.parseUnits('1000', 6),
    minAmountOut: quote.bestAmount.mul(995).div(1000), // 0.5% slippage
    routerType: quote.bestRouter
  });
  
  return tx;
}

Advanced Multi-Route

async function advancedRouting() {
  // Compare specific protocols only
  const preferredDEXes = [
    0,  // Uniswap V2
    10, // Uniswap V3  
    1,  // SushiSwap V2
    11, // SushiSwap V3
    30  // Curve
  ];
  
  const quotes = await aggregator.getQuotesForRouters(
    tokenIn,
    tokenOut, 
    amountIn,
    preferredDEXes
  );
  
  // Custom selection logic
  const bestQuote = quotes.find(q => 
    q.priceImpact < 0.5 && // Max 0.5% price impact
    q.gasEstimate < ethers.utils.parseUnits('200', 'gwei') // Reasonable gas
  ) || quotes[0]; // Fallback to best price
  
  return aggregator.executeSwap({
    ...swapParams,
    routerType: bestQuote.routerType
  });
}
