Swap Module

The Swap Module provides a comprehensive token swapping solution that integrates multiple DEX providers into a unified interface for the Solana blockchain. It automatically finds the best routes and prices across different protocols to maximize trading efficiency.

Core Features

Multi-Provider Support

Integrated support for Jupiter aggregation, Raydium pools, and PumpSwap custom routing

Intelligent Routing

Automatic route optimization to find the best prices and lowest fees across all DEXs

Real-time Pricing

Live price updates, slippage calculations, and fee estimates for informed trading decisions

Advanced Controls

Customizable slippage, provider selection, and transaction parameters for power users

Installation & Setup

Import Module

Import the swap components and hooks:

import { 
  SwapScreen,
  useSwapLogic,
  TradeService,
  SelectTokenModal 
} from '@/modules/swap';

Wallet Integration

Ensure Embedded Wallets are configured:

import { useWallet } from '@/modules/wallet-providers';

DEX Configuration

Configure DEX provider settings (optional):

const swapConfig = {
  defaultProvider: 'jupiter',
  slippageTolerance: 0.5,
  enableCustomPools: true
};

Module Architecture

The swap module is built with a modular, provider-agnostic architecture:

Primary DEX Aggregator - Best price discovery across all Solana DEXs

import { JupiterService } from '@/modules/swap';

// Get optimal swap quote
const quote = await JupiterService.getQuote({
  inputMint: 'So11111111111111111111111111111111111111112', // SOL

Performance Optimization

Quote Caching: Implement intelligent quote caching to reduce API calls and improve response times.

Rate Limiting: Be mindful of DEX API rate limits when implementing real-time price updates.

function useOptimizedQuoting() {
  const [quoteCache, setQuoteCache] = useState(new Map());
  const [lastQuoteTime, setLastQuoteTime] = useState(0);
  
  const getCachedQuote = (inputToken, outputToken, amount) => {
    const key = `${inputToken}-${outputToken}-${amount}`;
    const cached = quoteCache.get(key);
    
    if (cached && Date.now() - cached.timestamp < 10000) { // 10 second cache
      return cached.quote;
    }
    
    return null;
  };
  
  const fetchQuoteWithCache = async (inputToken, outputToken, amount) => {
    // Check cache first
    const cached = getCachedQuote(inputToken, outputToken, amount);
    if (cached) return cached;
    
    // Rate limiting
    const now = Date.now();
    if (now - lastQuoteTime < 1000) { // 1 second minimum between requests
      await new Promise(resolve => setTimeout(resolve, 1000 - (now - lastQuoteTime)));
    }
    
    const quote = await TradeService.getQuote(inputToken, outputToken, amount);
    
    // Cache result
    const key = `${inputToken}-${outputToken}-${amount}`;
    setQuoteCache(prev => new Map(prev.set(key, {
      quote,
      timestamp: Date.now()
    })));
    
    setLastQuoteTime(Date.now());
    return quote;
  };
  
  return { fetchQuoteWithCache };
}
