Decentralized finance (DeFi) has transformed the way users interact with digital assets, and 1inch Exchange stands at the forefront of this evolution. As a leading decentralized exchange aggregator, 1inch enables seamless cryptocurrency swaps across multiple platforms in a single transaction. Whether you're a seasoned trader or new to DeFi, understanding how to use 1inch Exchange can significantly enhance your trading efficiency, reduce costs, and improve access to liquidity.
This guide walks you through everything you need to know about using 1inch Exchange—from connecting your wallet to executing smart trades—while integrating key insights on security, optimization, and advanced features.
What Is 1inch Exchange?
1inch Exchange is a decentralized exchange (DEX) aggregator launched in 2019 by Sergej Kunz and Anton Bukov. Unlike traditional exchanges, 1inch doesn’t host its own order books. Instead, it scans multiple DEXs such as Uniswap, SushiSwap, and Balancer to find the most favorable rates for your trades.
By pooling liquidity from various sources, 1inch ensures users receive optimal pricing. Its proprietary algorithm, Pathfinder, analyzes hundreds of potential trade routes in real time, splitting large orders across different platforms to minimize slippage and maximize returns.

- Gas Optimization: Provides gas fee estimates and suggestions to reduce transaction costs.

These features make 1inch not just a trading platform but a comprehensive DeFi toolkit.
Step-by-Step Guide: How to Use 1inch Exchange
Using 1inch is straightforward and requires no sign-up—only a compatible crypto wallet. Follow these steps to get started.
Step 1: Connect Your Wallet
Begin by visiting the official 1inch dApp and selecting “Connect Wallet.” Supported wallets include:
- MetaMask
- WalletConnect
- Trust Wallet
- Ledger (via WalletConnect)
- Fortmatic and Portis (for email-based login)
Once connected, your wallet balance will appear, showing available tokens.
Security Tip: Always verify you're on the correct website (https://app.1inch.io) to avoid phishing scams.
Step 2: Select Tokens to Swap
Choose the cryptocurrency you want to trade from and the token you wish to receive. The interface supports thousands of ERC-20 tokens and other standards across supported blockchains like Ethereum, Binance Smart Chain, Polygon, Optimism, and Arbitrum.
You can search by symbol or paste a contract address to add custom tokens.
Step 3: Review Trade Details
After selecting your tokens, 1inch automatically calculates the best rate using its Pathfinder algorithm. The platform displays:
- Estimated amount received
- Price impact
- Liquidity source breakdown
- Network gas fees
You can toggle between different networks if you're using multi-chain wallets.

Step 4: Customize Settings (Optional)
Click the settings icon to adjust advanced options:
- Slippage Tolerance: Set acceptable price deviation (default is usually 0.5%–1%).
- Transaction Deadline: Define how long the transaction remains valid.
- Preferred DEXes: Choose specific exchanges to prioritize in routing.
For high-value trades, lowering slippage helps prevent front-running attacks.
Step 5: Confirm and Execute the Swap
Review all details carefully. Then click “Swap” and confirm the transaction in your wallet. Depending on network congestion, confirmation may take seconds to minutes.
Do not close the browser window until the transaction is finalized.
Step 6: Receive Your Tokens
Upon successful completion, the swapped tokens will appear in your connected wallet. You can track the transaction via Etherscan or equivalent explorers for other chains.
