1inch Exchange has emerged as one of the most trusted platforms in the decentralized finance (DeFi) ecosystem. Designed to optimize crypto trading across multiple decentralized exchanges (DEXs), 1inch delivers users the best possible rates by splitting transactions across various liquidity sources. This guide dives into how 1inch works, its core features, user experience, and why it's become a go-to tool for efficient token swapping.
What Is 1inch?
1inch is a decentralized exchange (DEX) aggregator that sources liquidity from multiple DEXs to provide users with the most favorable prices when trading cryptocurrencies. Unlike traditional exchanges that rely on a single order book, 1inch scans protocols like Uniswap, SushiSwap, Balancer, and others to find optimal trade routes — often combining several platforms in a single swap.
Launched in 2020, the platform introduced its native governance token, 1INCH, allowing holders to participate in decision-making through its decentralized autonomous organization (DAO). Users can earn 1INCH tokens by providing liquidity or participating in yield farming within the 1inch ecosystem.
Currently, 1inch supports major blockchain networks including Ethereum and Binance Smart Chain (BSC), making it accessible to a wide range of wallet users without requiring account registration.

Why Use 1inch for Crypto Swaps?
One of the standout benefits of using 1inch is cost efficiency. Thanks to its integration with tools like CHI GasToken, transaction fees on Ethereum can be reduced by up to 42%, especially during periods of high network congestion. This gas optimization helps users save significantly over time.
Additionally, 1inch offers:
- Best price routing: Algorithms split large trades across multiple DEXs to minimize slippage and maximize output.
- No KYC required: As a non-custodial platform, users retain full control of their funds via wallets like MetaMask.
- Transparent fee structure: All costs, including estimated gas fees and price impact, are displayed before confirming any trade.
These features make 1inch particularly appealing to experienced DeFi users who prioritize speed, security, and value.
Step-by-Step: How to Use 1inch Exchange
Using 1inch is straightforward, even for those new to decentralized trading. Here’s how to get started:
Step 1: Connect Your Wallet
To begin, visit 1inch.exchange and connect your crypto wallet. The most commonly used option is MetaMask, but other Web3 wallets are also supported.
Ensure you're on the correct network (e.g., Ethereum or BSC) before connecting. Once connected, you’ll see your wallet balance and available tokens.
Step 2: Navigate to the Exchange Tab
After connecting, click on the "Exchange" tab. You’ll be presented with a clean interface similar to other DeFi platforms — two fields for selecting the token you want to swap and the one you’d like to receive.
Use the refresh button to update prices in real-time or enable auto-refresh for continuous updates.
Step 3: Add Custom Tokens (If Needed)
If the token you're looking for isn’t listed, click the "+" icon to add it manually. You’ll need the token’s smart contract address — which you can find on sites like CoinGecko or Etherscan — ensuring it matches your current network (e.g., BSC or Ethereum).
Paste the contract address, verify details such as symbol and decimals, then add it to your list.
Step 4: Configure Swap Settings
Click on the Settings gear icon to adjust key parameters:
- Slippage Tolerance: Set how much price variation you’re willing to accept. A standard setting is 0.5%–1% to prevent failed transactions due to volatility.
- Gas Fee Options: Choose between faster (higher fee) or economical (lower fee) transaction speeds.
- Liquidity Sources: Select or exclude specific DEXs from being used in your trade route.

Executing a Token Swap on 1inch
Once configured, enter the amount of crypto you’d like to swap. If it's your first time trading a particular token, you may need to approve (unlock) it before proceeding.
This approval step authorizes 1inch to access your token balance. For frequent traders, selecting "infinite approval" reduces future gas costs, though it should be done cautiously only with trusted platforms.
After approval:
- Review the exchange rate, estimated fees, and savings compared to other platforms.
- Click "Swap", confirm the transaction in your wallet (e.g., MetaMask), and wait for blockchain confirmation.
Most swaps complete within seconds to minutes, depending on network traffic. Once done, your new tokens will appear in your wallet — typically with fees under $1 on BSC or optimized Ethereum layers.
Beyond Swaps: Liquidity Pools & Yield Farming
1inch isn’t just a swap tool — it also offers opportunities for passive income through:
- Liquidity Pools: Deposit token pairs into shared pools to earn trading fees.
- Yield Farming: Stake your LP tokens to earn additional rewards in 1INCH tokens.
These features encourage community participation while enhancing platform liquidity. Governance rights are tied to 1INCH holdings, enabling users to vote on proposals shaping the future of the protocol.
Is 1inch Safe? User Trust & Security Features
Security is central to 1inch’s design. Being a non-custodial platform means your funds never leave your wallet. Every transaction requires explicit approval through your connected wallet.
The platform has undergone third-party audits and employs smart contract safeguards to reduce risks like front-running and price manipulation. There have been no major security breaches reported since launch.
User reviews consistently highlight:
- Fast and reliable swaps
- Transparent pricing
- Responsive support
- Intuitive interface
While experiences may vary slightly based on network conditions, overall sentiment remains strongly positive across forums and crypto communities.
Tips for New Users
If you're new to DeFi or trying 1inch for the first time:
- Start with small transactions to test the process.
- Always double-check contract addresses when adding custom tokens.
- Monitor gas prices and choose appropriate network times for lower fees.
- Consider using BSC for cheaper trades if you're not tied to Ethereum-specific assets.
