Decentralized finance (DeFi) has revolutionized how users interact with digital assets, and one of the standout tools in this space is 1inch. As a powerful decentralized exchange (DEX) aggregator built on the Ethereum blockchain, 1inch enables users to swap ERC20 tokens efficiently while maximizing returns and minimizing losses from slippage and high gas fees.
This comprehensive guide walks you through everything you need to know about using 1inch—whether you're a beginner exploring DeFi for the first time or an experienced trader looking to optimize your on-chain transactions.
What Is 1inch?
1inch is a decentralized trading protocol designed to aggregate liquidity from multiple DEXs across the Ethereum network. By splitting trades across various platforms like Uniswap, SushiSwap, and Curve, it finds the most efficient route for token swaps—delivering better prices than any single exchange could offer alone.
The platform’s core innovation lies in its Pathfinder algorithm, which analyzes hundreds of liquidity pools in real time to determine optimal trade paths. In addition to instant swaps, 1inch supports limit orders, giving users greater control over their entry and exit points.
Key Benefits and Limitations of 1inch
Advantages:
- Access to Deep Liquidity: With integrations across dozens of major DEXs, 1inch provides access to nearly every tradable ERC20 token.
- Best Price Execution: Smart routing ensures users receive the most favorable rates by comparing prices across multiple sources.
- Gas Optimization Tools: Features like CHI GasToken help reduce transaction costs during peak network congestion.
- User-Friendly Interface: Integrated within popular wallets like imToken, accessing 1inch requires no technical setup.
Challenges:
- Ethereum Network Fees: Since most liquidity resides on Ethereum, users may face high gas fees during periods of network congestion.
- Complexity for Beginners: While intuitive, features like gas tokens and limit orders may require some learning curve.
Despite these limitations, 1inch remains a top choice for cost-conscious traders seeking efficiency and transparency in DeFi trading.
How to Use 1inch in imToken Wallet
Using 1inch directly from your imToken wallet is simple and secure. Follow these steps to start swapping tokens with minimal friction.
Step 1: Access 1inch via imToken DApp Browser
Open your imToken app and navigate to the DApp Browser. Use the search bar to look up "1inch" and select the official site. Always verify the URL (https://app.1inch.io) to avoid phishing sites.

Step 2: Connect Your Wallet
On your first visit, you’ll be prompted to connect your wallet. Tap “Connect Wallet” and choose imToken when prompted. This authorization is free and does not require gas.
Step 3: Select Tokens for Swap
Choose the token you want to trade from and the one you wish to receive. For example, select USDT as the input and BAT as the output. Enter the amount you'd like to swap.
1inch will instantly display the best available rate, including estimated gas cost and price impact.
Step 4: Approve Token Spending
Before swapping, you must approve 1inch to spend your selected token (e.g., USDT). Tap "Unlock" or "Approve", then confirm the transaction in your wallet.
For frequent traders, enabling "Infinite Unlock" avoids repeated approvals—but use this cautiously, as it grants ongoing access to your funds.
Step 5: Execute the Swap
Once approved, click "Swap Now", review all details, and confirm the transaction in imToken. Input your password and wait for blockchain confirmation.
Transaction speed depends on current Ethereum network conditions. You can track progress via Etherscan links provided in-app.
Step 6: Confirm Transaction Success
After confirmation, your new tokens (e.g., BAT) will appear in your wallet balance. Always double-check your holdings and transaction history for accuracy.
Reducing Gas Costs with CHI GasToken
High gas fees are a common pain point on Ethereum. To combat this, 1inch introduced CHI GasToken, an ERC20-compliant token that helps users save on transaction costs.
How CHI Works:
- Mint When Gas Is Low: Purchase and mint CHI tokens when network congestion is low (i.e., gas prices are cheap).
- Burn When Gas Is High: Use CHI during peak times to offset part of your transaction fee.
- Transferable & Tradeable: As an ERC20 token, CHI can be sent, stored, or traded like any other cryptocurrency.
While not automatic, strategic use of CHI can reduce cumulative gas expenses—especially beneficial for active traders performing frequent swaps.

Exploring Limit Order Functionality
Beyond instant swaps, 1inch offers limit orders, allowing users to set custom buy/sell prices.
How to Place a Limit Order:
- Switch from “Swap” to “Limit Order” mode in the interface.
- Specify desired price, input/output tokens, and amount.
- Sign the order—no upfront gas cost required.
- Once market conditions match your price, the order executes automatically via peer-to-peer relayers.
This feature brings centralized exchange-like precision to decentralized trading, ideal for users aiming to enter or exit positions at specific valuation levels.
Important Tips for Efficient Trading on 1inch
To get the most out of 1inch, consider these best practices:
- Prioritize Gas Fees for Small Trades: If trading small amounts, even minor gas fluctuations can outweigh slippage savings. Optimize for lower gas execution.
- Focus on Slippage for Large Swaps: For larger transactions, price impact becomes more significant than gas. Use tight slippage tolerance (adjustable in settings).
- Monitor Network Activity: Tools like ETH Gas Station help predict optimal times to transact.
- Use Native Wallet Integration: Conducting trades through trusted wallets like imToken adds a layer of security.
Frequently Asked Questions (FAQ)
Q: Is 1inch safe to use with my crypto wallet?
A: Yes. 1inch is a non-custodial service—your funds never leave your wallet. Transactions are signed locally, ensuring full control over your assets.
Q: Why do I need to approve tokens before swapping?
A: Token approval is a security feature of the ERC20 standard. It allows protocols to move specific tokens on your behalf, but only up to the approved amount.
Q: Can I use 1inch on blockchains other than Ethereum?
A: Yes. While originally built for Ethereum, 1inch now supports multiple chains including Binance Smart Chain, Polygon, Optimism, Arbitrum, and Avalanche.
Q: What happens if my transaction fails?
A: Failed swaps typically result from price volatility exceeding slippage tolerance. You’ll lose gas fees but retain original tokens. Adjust slippage settings (e.g., increase to 1–3%) to improve success rates.
Q: Does 1inch have its own governance token?
A: Yes. The 1INCH token serves as the platform’s governance and utility token, distributed through liquidity mining programs and used for voting on protocol upgrades.
Q: How does 1inch compare to other DEX aggregators?
A: 1inch stands out due to its advanced routing algorithms, broad chain support, and innovative tools like CHI GasToken and limit orders—making it one of the most feature-rich aggregators available.
