RoutesX

Overview

RoutesX is a decentralized exchange (DEX) aggregator that combines the power of 1inch aggregation protocol with Uniswap V3 concentrated liquidity pools to find the most optimal trading routes for token swaps.

The Problem

DeFi users face a fragmented liquidity landscape:

Scattered liquidity: Liquidity spread across dozens of DEXs
Suboptimal pricing: Single-source swaps miss better rates
High gas costs: Multiple transactions for best prices
Complex routing: Multi-hop routes hard to discover

Solution

RoutesX solves these problems by:

Aggregating liquidity from multiple sources
Finding optimal routes across DEXs
Splitting orders for better execution
Minimizing gas through efficient routing

Key Features

Multi-Source Aggregation

Queries multiple liquidity sources simultaneously:

1inch aggregation (covers 50+ DEXs)
Uniswap V3 direct pools
Custom routing algorithms

Gas Optimization

Smart gas calculations:

typescript

// Estimate gas for each route
const routes = await Promise.all([
  get1inchQuote(tokenIn, tokenOut, amount),
  getUniswapV3Quote(tokenIn, tokenOut, amount),
]);
 
// Factor in gas costs for true comparison
const bestRoute = routes.reduce((best, route) => {
  const totalCost = route.outputAmount - route.gasCost;
  return totalCost > best.totalCost ? route : best;
});

Multi-Hop Routing

Supports complex routing through intermediate tokens:

plaintext

USDC → WETH → UNI (2 hops)
USDC → WETH → WBTC → UNI (3 hops)

Smart Contract Integration

1inch Integration

solidity

// 1inch aggregation router interaction
interface I1inchRouter {
    function swap(
        IAggregationExecutor executor,
        SwapDescription calldata desc,
        bytes calldata permit,
        bytes calldata data
    ) external returns (uint256 returnAmount);
}
