Decentralized finance (DeFi) continues to reshape how users interact with digital assets, and at the forefront of this evolution stands 1inch Exchange—a powerful decentralized exchange (DEX) aggregator designed to optimize cryptocurrency trading. Whether you're a seasoned DeFi trader or just beginning your journey, understanding 1inch’s capabilities can significantly enhance your trading efficiency, cost savings, and access to liquidity.
This comprehensive guide dives deep into how 1inch works, its standout features, tokenomics, and how it compares to competitors—giving you everything you need to make informed decisions in the fast-moving world of DeFi.
What Is 1inch Exchange?
1inch Exchange is a decentralized exchange (DEX) aggregator that combines two core functions:
- DEX Swaps
- DEX Aggregation
Unlike traditional DEXs where trades occur within a single protocol’s liquidity pool, 1inch scans multiple decentralized exchanges simultaneously to find the best available rates for users. This means when you swap tokens on 1inch, the platform may split your trade across several DEXs like Uniswap, SushiSwap, Curve, and Balancer—ensuring maximum value and minimal slippage.

The key differentiator? Smart order routing powered by advanced algorithms. 1inch uses proprietary technology called Pathfinder to analyze hundreds of liquidity sources in real time, identifying the most cost-effective path for any given swap. This process happens seamlessly in one transaction—saving users time, gas fees, and potential losses from poor pricing.
Because it operates as a non-custodial platform, no KYC is required, and users retain full control of their funds at all times. All you need is a compatible crypto wallet like MetaMask or WalletConnect to get started.
The Origins of 1inch
Founded in March 2019 by Russian developers Sergej Kunz and Anton Bukov, 1inch began as a Minimum Viable Product (MVP) during the ETHNewYork hackathon. The duo leveraged their experience in Ethereum smart contract security and arbitrage bot development to build a system that automatically routes trades across DEXs for optimal pricing.
Their early prototype aggregated liquidity from major platforms like Bancor, Kyber Network, and Uniswap—laying the foundation for what would become one of the most trusted names in DeFi aggregation.
Key Features of 1inch Exchange
Liquidity Aggregation Protocol
At its core, 1inch pulls liquidity from over 50+ decentralized exchanges across multiple blockchains. By aggregating depth from various sources, it ensures deeper liquidity pools and better price discovery than most standalone DEXs.
This is especially beneficial for large trades that might otherwise suffer high slippage on a single exchange. Instead of relying on one pool, 1inch fragments your order into smaller parts and executes them across multiple venues—minimizing market impact.
Limit Order Protocol
One of the biggest limitations of early DEXs was the lack of advanced trading tools. Most only supported instant swaps. 1inch changed that by introducing a limit order protocol in June 2021.
Traders can now:
- Place limit orders
- Set stop-loss triggers
- Use trailing stops
- Participate in auction-based trading
Best of all? These advanced features come with zero service fees—a major advantage over centralized exchanges that charge premiums for such tools.
Multi-Chain Integration
Originally built on Ethereum, 1inch has expanded to support numerous Layer 1 and Layer 2 networks, including:
- Binance Smart Chain (BSC)
- Polygon
- Optimism
- Arbitrum
- Avalanche
- Gnosis Chain
This multi-chain support allows users to avoid high Ethereum gas fees during peak congestion while still accessing robust DeFi functionality. For example, on BSC, 1inch routes trades through PancakeSwap and Venus Protocol instead of Uniswap or SushiSwap.

Reduced Gas Fees with Chi Gastoken
High gas costs on Ethereum have long been a pain point for DeFi users. To address this, 1inch introduced CHI Gastoken in June 2021—a tokenized gas optimization tool.
Here’s how it works:
- Users mint CHI when gas prices are low.
- They burn CHI during periods of high network congestion to offset transaction costs.
- This effectively smooths out gas expenses over time.
While not usable on every transaction type, CHI provides a strategic way to reduce overhead—especially for frequent traders.
No Trading Fees
Unlike many exchanges that take a cut of each trade (typically 0.3%), 1inch charges no additional trading fees. You only pay the standard blockchain network fee (gas) and any fees imposed by the underlying DEXs involved in the swap.
In many cases, due to efficient routing, your total cost ends up lower than if you had used a single DEX directly.
How Does 1inch Work?
Behind the scenes, 1inch relies on sophisticated smart contracts and algorithms to deliver optimal results:
- Query Submission: When you input a swap (e.g., wBTC → LINK), 1inch's Pathfinder API evaluates thousands of potential routes.
- Route Optimization: It considers factors like price impact, slippage tolerance, gas consumption, and available liquidity.
- Order Splitting: If beneficial, your trade is split across multiple DEXs and executed in a single atomic transaction.
- Execution & Settlement: All steps happen in one go—ensuring security and finality without requiring user intervention.
For uncommon token pairs without direct liquidity pools (like wBTC → LINK), 1inch may route through intermediate assets (e.g., wBTC → WETH → LINK), choosing paths that minimize losses.
Users maintain full control throughout:
- Adjustable slippage tolerance (minimum 0.1%)
- Customizable gas fee settings (low, average, fast, instant)
- Option to enable partial execution to prevent failed transactions
- Choice of liquidity sources to include or exclude
How Does 1inch Compare to Competitors?
While several DEX aggregators exist, 1inch remains a market leader due to its advanced tech stack and broad ecosystem integration.
| Aggregator | Native Token | Chains Supported | Key Differentiator |
|---|---|---|---|
| 1inch | 1INCH | 12+ | Pathfinder routing, limit orders |
| Paraswap | PSP | 9+ | Smart routing with slippage protection |
| Matcha | None | 7+ | User-friendly interface |
| CoW Swap | COW | 3+ | MEV-resistant batch auctions |
Although competitors offer similar routing capabilities, few match 1inch’s combination of limit orders, multi-chain reach, and gas optimization tools like CHI.
Additionally, its open API allows developers to integrate 1inch’s aggregation engine into their own dApps—further expanding its utility in the DeFi landscape.
Roadmap and Development Milestones
Since its inception, 1inch has consistently evolved with key upgrades:
- Aug 2020: Launched Mooniswap—an AMM designed to reduce impermanent loss using price delays.
- Nov 2020: Released v2 with Pathfinder routing algorithm for faster, more efficient swaps.
- Dec 2020: Introduced the 1INCH token and launched the 1inch DAO.

What Is Chi Gastoken (CHI)?
As mentioned earlier, CHI is a gas-efficient token designed specifically for Ethereum transactions. It operates on the principle of "buy low, burn high"—allowing users to pre-pay for future gas during off-peak hours.
While not mandatory, integrating CHI into regular trading can yield significant savings during volatile market conditions when gas prices spike unexpectedly.
