Token Swap Aggregator
Compare swap rates across multiple DEX aggregators to get the best price for your crypto trades. Save on fees with optimized routing.
Compare Swap Rates
ℹ️ How This Works
- • We compare real-time quotes from 4 major DEX aggregators
- • Gas costs are estimated based on current network conditions
- • "Net Output" = Output Amount - Gas Fees (your actual profit)
- • Routes show which DEXs your trade would be split across
- • CowSwap offers gasless swaps via batch auctions (MEV protected)
- • Always verify rates on the actual aggregator before swapping
What is a Token Swap Aggregator?
A token swap aggregator is a tool that compares prices across multiple decentralized exchanges (DEXs) and DEX aggregators to find you the best rate for swapping one cryptocurrency for another. Instead of checking multiple platforms manually, aggregators do the work for you in seconds.
Popular DEX aggregators like 1inch, Paraswap, and CowSwapalready aggregate liquidity from dozens of DEXs (Uniswap, Sushiswap, Curve, etc.). Our tool goes one step further by comparing these aggregators themselves, ensuring you get the absolute best rate available.
Beyond just finding the best price, aggregators optimize swap routes to minimize slippage, reduce gas fees, and protect against MEV (Miner Extractable Value) attacks. This can save you hundreds of dollars on large trades.
How to Use the Token Swap Aggregator
1. Select Your Network
Choose the blockchain network you want to swap on (Ethereum, BSC, Polygon, Arbitrum, etc.). Different networks have different available DEXs and gas fee structures.
2. Enter Token Pair
Select the token you're swapping FROM and the token you want to receive (TO). You can search by token name or paste the contract address for any ERC-20 token.
3. Input Amount
Enter the amount you want to swap. The calculator will fetch real-time quotes from multiple aggregators and show you the output amount you'll receive from each.
4. Compare Results
Review the comparison table showing rates from 1inch, Paraswap, CowSwap, and other aggregators. The table includes output amount, gas costs, total fees, and effective rate per token.
5. Adjust Slippage (Optional)
Set your maximum acceptable slippage tolerance (default is 0.5%). Higher slippage allows swaps to execute even if prices move, but you might get a worse rate.
Key Features
🔍 Multi-Aggregator Comparison
Compare rates from 1inch, Paraswap, CowSwap, and other top aggregators in real-time. See exactly which platform offers the best rate for your specific trade.
⚡ Gas Cost Estimation
View estimated gas fees for each aggregator. Sometimes a slightly worse rate with lower gas can be more profitable, especially for smaller trades.
🛡️ MEV Protection
See which aggregators offer MEV protection (like CowSwap's batch auctions). Protect yourself from frontrunning and sandwich attacks on large trades.
📊 Route Visualization
Understand the swap path: see which DEXs your trade will route through, how liquidity is split, and why one aggregator found a better route than another.

Example Calculations
Example 1: ETH → USDC Swap ($5,000)
Input: 2.5 ETH @ $2,000/ETH
Expected Output: ~$5,000 USDC
Results:
- • 1inch: 4,987 USDC (gas: $8) → Net: $4,979
- • Paraswap: 4,992 USDC (gas: $12) → Net: $4,980
- • CowSwap: 4,994 USDC (gas: $0) → Net: $4,994 ✅ Best
Winner: CowSwap saves $14 due to gasless execution and MEV protection
Example 2: Small Swap - USDC → DAI ($100)
Input: 100 USDC
Expected Output: ~99.9 DAI (stablecoin pair)
Results:
- • 1inch: 99.85 DAI (gas: $6) → Net: $93.85
- • Paraswap: 99.87 DAI (gas: $8) → Net: $91.87
- • CowSwap: 99.88 DAI (gas: $0) → Net: $99.88 ✅ Best
Key Insight: For small swaps, gas fees matter more than tiny rate differences. CowSwap's gasless execution is ideal for trades under $1,000.
Example 3: Large Trade - WBTC → ETH ($50,000)
Input: 1 WBTC @ $50,000
Expected Output: ~25 ETH @ $2,000/ETH
Results:
- • 1inch: 24.89 ETH (gas: $22) → Net: $49,758
- • Paraswap: 24.94 ETH (gas: $18) → Net: $49,862 ✅ Best
- • CowSwap: 24.91 ETH (gas: $0) → Net: $49,820
Key Insight: For large trades, rate differences outweigh gas savings. Paraswap's MultiPath routing found $100+ better execution despite higher gas.
Understanding Slippage & MEV Protection
What is Slippage?
Slippage is the difference between the expected price of a trade and the actual executed price. It happens because prices can move between the time you submit a transaction and when it's confirmed on-chain. High slippage tolerance (e.g., 5%) means you're willing to accept a worse price to ensure your trade executes, while low tolerance (0.1%) might cause transaction failures if prices move.
MEV (Maximal Extractable Value)
MEV refers to profits that miners/validators can extract by reordering, inserting, or censoring transactions in blocks. In DeFi swaps, this often manifests as "sandwich attacks" where bots place trades before and after yours to profit from your price impact. This can cost you 1-3% on large trades.
How to Protect Yourself
- Use CowSwap for MEV-protected swaps via batch auctions
- Set low slippage tolerance (0.1-0.5%) to limit sandwich attack profitability
- Split large trades into smaller chunks across multiple transactions
- Use private RPC endpoints (e.g., Flashbots Protect) to hide your transaction from public mempool
- Trade during low volatility periods when price movements are minimal
Frequently Asked Questions
Which DEX aggregator is the best?
It depends on your trade: CowSwap is best for MEV protection and small swaps (gasless),1inch excels at finding routes across 300+ DEXs, and Paraswap often wins on large trades with complex routing. Always compare rates for your specific trade.
Do aggregators charge fees?
Most aggregators charge a small fee (0.05-0.3%) built into the quoted rate. For example, 1inch charges 0.3% which is often offset by better rates they find. Some aggregators (like Paraswap) offer gas refunds via their native tokens to reduce costs.
How do aggregators find better rates than DEXs?
Aggregators check dozens of DEXs simultaneously and can split your trade across multiple paths. For example, to swap 10 ETH for DAI, an aggregator might route 6 ETH through Uniswap, 3 ETH through Curve, and 1 ETH through Balancer—getting better overall pricing than any single DEX could offer.
Are DEX aggregators safe to use?
Yes, reputable aggregators like 1inch, Paraswap, and CowSwap are non-custodial (you keep control of your funds) and have been audited multiple times. However, always verify you're on the official website (check URLs carefully) and revoke token approvals after large trades to minimize smart contract risk.
What's the difference between slippage and price impact?
Price impact is how much your trade moves the market price (large trades on low-liquidity pools cause high impact). Slippage is additional price movement that happens between transaction submission and execution. Set slippage tolerance to account for both, typically 0.5% for stable markets and 1-2% for volatile tokens.
Can I use aggregators for limit orders?
Yes! Both 1inch and CowSwap support limit orders. You can set a target price and the order will execute automatically when that price is reached on any DEX they monitor. This is useful for buying dips or taking profits without watching charts 24/7.
