Decentralized exchanges (DEXs) are transforming how users trade cryptocurrencies by removing intermediaries and giving traders full control over their funds. Among these innovative platforms, 1inch stands out as a powerful player in the decentralized finance (DeFi) ecosystem. It combines the functionality of a DEX with an advanced aggregator that finds optimal trading routes across multiple platforms.
This guide explores everything you need to know about 1inch, including how it works, its core features, tokenomics, and how to use it safely and effectively.
The Evolution of 1inch Exchange
1inch was founded in March 2019 by two Russian developers, Sergej Kunz and Anton Bukov. Before launching the platform, the founders were deeply involved in Ethereum smart contract security audits and participated in several international hackathons. Their work earned early support from notable DeFi projects like MakerDAO, Set Protocol, and Kyber Network.
Their breakthrough came during the ETHNewYork hackathon, where they launched the first Minimum Viable Product (MVP) of 1inch. This prototype aggregated liquidity from existing DEXs such as Bancor, Kyber, and Uniswap—laying the foundation for what would become one of the most efficient decentralized trading tools.
Since then, 1inch has evolved into a multi-chain powerhouse, continuously improving its routing algorithms and expanding its suite of DeFi tools.

What Is the 1inch Exchange?
The 1inch exchange is a cutting-edge decentralized platform that functions both as a DEX and a DEX aggregator. This dual functionality makes it uniquely valuable in the DeFi space.
Key Features:
- DEX Platform: Enables direct peer-to-peer cryptocurrency trading.
- DEX Aggregator: Searches across multiple exchanges to find the best available prices.
- Multi-chain Integration: Supports Ethereum, Binance Smart Chain (BSC), Polygon, Avalanche, Arbitrum, Optimism, and more.
- Low Trading Fees: No additional fees on trades; users only pay network gas costs.
- Limit Order Protocol: Offers advanced order types like stop-loss and trailing-stop orders.
Unlike traditional DEXs that rely on a single liquidity pool, 1inch scans over 50+ decentralized exchanges to ensure users get the most favorable rates. It can split large trades across multiple platforms to minimize slippage and reduce overall costs.
Why Use 1inch?
Slippage—the difference between expected and executed trade prices—is a major concern in low-liquidity markets. By intelligently routing trades and fragmenting orders, 1inch significantly reduces slippage, especially for high-value transactions.
Additionally, because it's fully decentralized, no KYC is required, and users retain complete custody of their assets at all times.
How Does 1inch Work?
At its core, 1inch uses sophisticated algorithms to identify the most cost-effective path for token swaps. When you initiate a trade, the platform evaluates various routes across supported DEXs and determines the optimal combination of exchanges to fulfill your order.
For example, if you want to swap wBTC for LINK but there’s no direct liquidity pair available, 1inch might route your trade through intermediate assets like ETH—executing wBTC → ETH → LINK in a single transaction.
Core Mechanisms:
- Pathfinder Algorithm: Introduced in v2, this system finds the fastest and cheapest swap paths while considering gas fees.
- Order Splitting: Divides large trades into smaller chunks across different DEXs to avoid price impact.
- Gas Optimization: Automatically selects efficient transaction methods to lower network costs.
This automated approach not only saves time but also outperforms manual trading strategies in terms of cost efficiency and execution speed.
How to Use the 1inch Exchange
Using 1inch is straightforward and accessible to both beginners and experienced traders.
Step-by-Step Process:
- Connect Your Wallet: Supported wallets include MetaMask, Coinbase Wallet, and any WalletConnect-compatible app.
- Select Network: Choose from Ethereum, BSC, Polygon, Avalanche, or Layer 2 solutions like Arbitrum and Optimism.
- Enter Swap Details: Pick your input and output tokens, along with the amount.
Adjust Settings:
- Set gas price (low, average, high, or instant).
- Define slippage tolerance (minimum 0.1%).
- Enable partial fill to prevent failed transactions.
- Choose specific liquidity sources or exclude certain DEXs.
- Review & Confirm: Approve the transaction in your wallet.
Advanced users can also place limit orders, allowing them to set target prices for future trades without constant monitoring.
1inch vs. Competitors: How Does It Stack Up?
While several DEX aggregators exist, 1inch leads in adoption, performance, and feature richness. Let's compare it with key alternatives:
| Feature | 1inch | 0x | SwapZone | Orion |
|---|---|---|---|---|
| Multi-chain Support | ✅ Yes | ✅ Yes | ❌ Limited | ✅ Yes |
| No Service Fees | ✅ Yes | ❌ Charges fees | ✅ Yes | ✅ Yes |
| Limit Orders | ✅ Native support | ❌ | ❌ | ❌ |
| Governance Token | ✅ 1INCH | ✅ ZRX | ❌ | ✅ ORN |
Competitors like 0x charge service fees and lack native limit order functionality. Others such as SwapZone and SwapMatic are limited in chain coverage or depth of features.

Roadmap and Development History
1inch has consistently pushed innovation forward through strategic upgrades:
- 2020 (v1): Launched MVP during ETHNewYork; aggregated liquidity from Uniswap, Bancor, and Kyber.
- August 2020: Introduced Mooniswap, an AMM designed to resist front-running via delayed pricing.
- November 2020 (v2): Upgraded with Pathfinder, improving route calculation speed and gas efficiency.
- December 2020: Launched the 1INCH token and established a DAO for community governance.
- June 2021: Released the Limit Order Protocol, enhancing trading flexibility.
The project has raised nearly $190 million in funding across Series A and B rounds—highlighting strong institutional confidence in its long-term vision.
What Is the 1INCH Token?
The 1INCH token is the native utility and governance token of the 1inch ecosystem.
Key Uses:
- Governance: Vote on protocol upgrades and treasury allocations.
- Utility: Used within the liquidity protocol for efficient routing.
- Multi-chain Availability: Exists on both Ethereum (ERC-20) and BSC via cross-chain bridge.
Token Distribution (Total Supply: 1.5 Billion)
- Community Incentives: 30%
- Core Contributors: 22.5%
- Network Growth Fund: 14.5%
- Early Sponsors: 30.7%
- Small Sponsors: 2.3%
A significant portion—6%—was distributed via airdrop to early users who traded or provided liquidity before September 2020.
As of early 2025, approximately 415 million tokens are in circulation, with full vesting scheduled by December 2024.
What Is CHI Gastoken?
Introduced in June 2021, CHI Gastoken helps users reduce Ethereum gas costs during periods of high network congestion.
How CHI Works:
- Users mint CHI when gas prices are low.
- Burn CHI during high-gas periods to offset transaction fees.
- Price of CHI correlates directly with Ethereum’s base fee.
This mechanism allows traders to hedge against volatile gas markets—an especially useful tool for frequent DeFi users.
Should You Buy 1INCH?
Investing in any cryptocurrency requires thorough research. While 1inch has demonstrated strong technical innovation and growing adoption, price performance depends on broader market conditions and DeFi trends.
Historically, the 1INCH token reached an all-time high of $7.87 in May 2021, but prices have since corrected. Always assess fundamentals—such as usage metrics, development activity, and ecosystem growth—before investing.
