1inch Exchange is one of the most innovative decentralized exchanges (DEXs) shaping the future of decentralized finance (DeFi). Designed to make crypto trading more efficient, accessible, and cost-effective, 1inch stands out by combining the functionality of a traditional DEX with the power of a multi-source aggregator. Whether you're swapping tokens, managing liquidity, or staking governance tokens, 1inch offers a comprehensive toolkit for both beginners and advanced users in the DeFi space.
This guide dives deep into how 1inch works, its core protocols, multi-chain capabilities, tokenomics, and practical steps to use and benefit from the platform.
How 1inch Exchange Was Created
1inch Exchange was founded in March 2019 by Russian developers Sergey Kunz and Anton Bukov. Before launching the platform, Kunz hosted YouTube livestreams reviewing Ethereum smart contract security, while both developers actively participated in international blockchain hackathons. Their work earned sponsorships from major DeFi projects like MakerDAO, Set Protocol, and Kyber Network.
Their experimentation with arbitrage bots led to the creation of the initial 1inch blueprint. The pivotal moment came during the ETHNewYork hackathon, where they developed the minimum viable product (MVP) for 1inch Exchange. This early version aggregated liquidity from major DEXs such as Bancor, Kyber, and Uniswap—laying the foundation for what would become a leading DEX aggregator.
What Is 1inch Exchange?
1inch Exchange is a revolutionary decentralized trading platform that uniquely combines two critical functions:
- A decentralized exchange (DEX) for direct token swaps
- A DEX aggregator that sources liquidity across multiple platforms
While it allows users to swap cryptocurrencies similarly to Uniswap or SushiSwap, its true innovation lies in its aggregation technology. The 1inch DEX Aggregator scans dozens of decentralized exchanges simultaneously to find the best available price for any given trade.
It achieves this by:
- Splitting large orders across multiple DEXs
- Minimizing slippage through optimized routing
- Reducing gas costs using smart contract efficiency
This approach ensures traders get better rates than they would on any single exchange—especially important for large trades or less liquid token pairs.

Core Features of 1inch Exchange
1inch enhances DeFi trading with several advanced protocols:
Liquidity Protocol
Initially built to aggregate external liquidity, 1inch later launched its own liquidity protocol featuring MooniSwap, an automated market maker (AMM) designed to reduce losses from front-running attacks. While MooniSwap introduced time-delayed pricing to deter arbitrage bots, the platform continues to rely heavily on external liquidity sources due to challenges in attracting long-term liquidity providers (LPs).
Aggregation Protocol (v3)
Launched in March 2021, the v3 Aggregation Protocol significantly improved speed and efficiency. It connects over 50 DEXs across Ethereum, Binance Smart Chain (BSC), Avalanche, Polygon, Arbitrum, Optimism, and Gnosis Chain. This cross-chain integration allows users to access deep liquidity regardless of the network they're on.
Limit Order Protocol
Unlike most DEXs that only support market orders, 1inch offers a powerful Limit Order Protocol—allowing users to place stop-loss orders, trailing stops, and auctions. Notably, no fees are charged for using this feature, making it highly attractive for precision traders.
Multi-Chain Integration
To combat high Ethereum gas fees, 1inch supports multiple blockchains including BSC, Avalanche, Polygon, Arbitrum, Optimism, and Gnosis Chain. For example, when operating on BSC, 1inch routes trades through PancakeSwap or Venus instead of Uniswap—ensuring seamless performance with lower costs.
Low Transaction Costs
While 1inch does not charge service fees, users still pay standard blockchain gas fees. However, thanks to intelligent routing and batch processing, transaction costs are often lower than executing trades directly on platforms like Uniswap or Curve.
How Does 1inch Work?
At its core, 1inch uses smart routing algorithms—powered by its proprietary Pathfinder technology—to identify the optimal path for token swaps. When you initiate a trade:
- The system scans multiple DEXs for price and liquidity data
- It splits your trade across several platforms if needed
- All actions are executed in a single transaction
For example, if you want to swap wBTC to LINK but no single pool supports that pair efficiently, 1inch might route it as:
wBTC → ETH → LINK, pulling liquidity from different exchanges to minimize slippage and maximize output.
This intelligent fragmentation is particularly valuable for large trades or low-cap tokens where direct swaps would result in poor pricing or failed transactions.
Why Use 1inch Exchange?
Here’s why thousands of traders choose 1inch:
- ✅ User-friendly interface with advanced customization
- ✅ No platform fees – only blockchain gas costs apply
- ✅ Access to best available prices via multi-source aggregation
- ✅ Support for limit orders, stop-losses, and auctions
- ✅ Full control over slippage tolerance and gas pricing
- ✅ Compatibility with popular wallets like MetaMask and WalletConnect
- ✅ Multi-chain support across Ethereum, BSC, Polygon, Avalanche, and more
- ✅ Enhanced security with non-custodial architecture
Additionally, liquidity providers can earn yield by depositing assets into pools and receiving LP tokens usable in other DeFi protocols.
How to Use 1inch Exchange
Using 1inch is simple:
- Visit app.1inch.io
- Connect your wallet (MetaMask, Coinbase Wallet, WalletConnect-supported options)
- Select your source and target tokens
Adjust settings:
- Gas price (low/medium/high/instant)
- Slippage tolerance (minimum 0.1%)
- Partial fill preference
- Liquidity source selection
- Review quote and confirm transaction
You can also add custom tokens via contract address and use compatibility mode for fee-on-transfer tokens.
1inch vs. Competitors
While several DEX aggregators exist, few match 1inch’s scale and functionality. Key competitors include:
- 0x (0x API) – Charges service fees; strong developer tools
- SwapZone – Focuses on instant swaps with no registration
- Orion Protocol – Operates on Ethereum and BSC; includes cross-chain bridge
- SwapMatic – Covers Ethereum, Polygon, BSC; offers staking rewards
Despite competition, 1inch leads in volume, supported chains, and feature richness. Its main advantage over rivals like 0x is the absence of platform fees. Moreover, SwapZone and SwapMatic lack full multi-chain coverage, limiting their reach compared to 1inch’s broad ecosystem integration.

Price and Forecast
The 1INCH token reached an all-time high of **$7.87 on May 8, 2021**, but traded around $1.50 in early 2022. Market forecasts suggest volatility ahead due to broader crypto trends. Some analysts project potential downside pressure in bear markets but emphasize long-term value tied to protocol adoption.
What Is CHI GasToken?
Launched in June 2021, the CHI GasToken helps users reduce Ethereum transaction costs. It acts as a tokenized form of gas—allowing users to "store" gas when prices are low and use it later during peak congestion.
By minting CHI when gas is cheap and burning it when gas is expensive, traders can significantly cut costs—especially beneficial during high-volatility periods or NFT mints.
Should You Buy 1INCH?
Investing in 1INCH should follow thorough research into its technology and governance model. While it offers real utility in DeFi operations—especially for frequent traders and liquidity providers—it remains subject to market risks like any crypto asset.
Staking 1INCH grants voting rights in the DAO but currently offers no direct yield rewards.
