Decentralized Exchanges (DEXs) have gained widespread popularity for offering users greater control over their assets. With benefits like self-custody, no mandatory KYC, broader token selection, and resistance to censorship, DEXs present a compelling alternative to centralized platforms. However, they are not without challenges—low liquidity, high slippage, and expensive gas fees often hinder smooth trading experiences.
Enter 1inch Exchange, a non-custodial decentralized exchange aggregator designed to solve some of the most pressing issues in the DeFi space. By sourcing liquidity from multiple DEXs, 1inch ensures users get the best possible rates while minimizing slippage and transaction costs.

What Is 1inch Exchange?
1inch Exchange was co-founded by Russian developers Sergei Kunz and Anton Bukov, who initially met while auditing smart contracts. Their experience in blockchain security—earning bounties at hackathons for projects like MakerDAO, Set Protocol, and Kyber Network—laid the foundation for building a robust, user-first DeFi tool.
At its core, 1inch is a DEX aggregator. Instead of relying on a single exchange’s order book, it scans multiple decentralized platforms such as Uniswap, SushiSwap, Curve, and Balancer to find the most efficient trading routes. This approach consolidates fragmented liquidity across the Ethereum ecosystem (and other supported chains), enabling better pricing and reduced slippage.
All trades occur directly from your wallet—no deposits required. Transactions are executed in a single click, maintaining full user control throughout the process.
Key Features of 1inch Exchange
1inch stands out in the crowded DeFi landscape due to its innovative features tailored for both novice and advanced traders.
Unified Liquidity Across DEXs
The platform pulls pricing and liquidity data from numerous decentralized exchanges, presenting users with optimal trade routes. This means you’re no longer limited to one DEX’s shallow pool—you access aggregated depth across the ecosystem.
Non-Custodial Architecture
Unlike centralized exchanges that hold your funds, 1inch never takes custody of your assets. Every transaction is signed and executed through your Ethereum-compatible wallet, ensuring complete ownership at all times.
No KYC or Account Registration
There’s no need to create an account or submit personal information. Simply connect your wallet and start trading immediately—ideal for privacy-conscious users.
Enhanced Security Model
Since 1inch doesn’t store user funds or private keys, it’s inherently less vulnerable to hacks. There are no centralized reserves for attackers to target, significantly reducing attack surfaces.
Smart Order Splitting
Large trades are automatically split across multiple DEXs to minimize slippage. This intelligent routing ensures better execution prices than what’s typically available on individual platforms.
Understanding 1inch Exchange Fees
One of the biggest advantages of using 1inch is its transparent and user-friendly fee structure.
- No Trading or Withdrawal Fees: 1inch does not charge any commission on trades or withdrawals.
- Gas Fees Apply: Since transactions occur on-chain (primarily Ethereum), users must pay standard network gas fees.
- CHI Gas Token Optimization: To reduce transaction costs, 1inch introduced CHI, a gas token that can lower fees by up to 42% during periods of high network congestion. Users who pay with CHI enjoy cheaper swaps without sacrificing speed or reliability.
This cost-efficient model makes 1inch especially attractive during volatile market conditions when gas prices spike.
Wallets Supported by 1inch
1inch supports a wide range of ERC-20 compatible wallets, making it accessible to most DeFi users. Supported options include:
- MetaMask
- Trust Wallet
- Ledger (via Web3 integration)
- WalletConnect
- Torus
- Portis

Behind the scenes, 1inch’s Pathfinder algorithm analyzes hundreds of liquidity pools to deliver the best rate, often splitting your order across several DEXs for maximum efficiency.
The Role of the 1INCH Token
The 1INCH token is the native utility and governance token of the 1inch Network. It serves several key functions:
- Governance: Token holders can vote on protocol upgrades, fee models, and future developments.
- Staking: Users can stake 1INCH tokens to earn rewards and help secure the network.
- Ecosystem Funding: A portion of protocol revenue is used to buy back and burn 1INCH tokens, creating deflationary pressure over time.
Launched in December 2020, the token distribution emphasized fairness and decentralization, with significant allocations going to early users and liquidity providers.
Is 1inch Exchange Safe?
Yes—security is one of 1inch’s strongest selling points.
As a non-custodial aggregator, it doesn’t hold user funds at any point. All transactions are executed directly from your wallet via signed messages, meaning only you control your private keys.
Additionally:
- The smart contracts have undergone multiple third-party audits.
- The platform has maintained a clean security record since launch—no major exploits or breaches reported.
- Open-source code allows continuous community review and transparency.
While no system is entirely immune to risk (especially in DeFi), 1inch employs best-in-class practices to protect users.
