Decentralized finance (DeFi) continues to reshape the crypto landscape, and at the forefront of this evolution stands 1inch Exchange — a powerful decentralized exchange (DEX) and DeFi aggregator known for its efficiency, transparency, and user-centric design. Since its launch in 2019, 1inch has emerged as a go-to platform for traders seeking optimal swap rates, low fees, and advanced trading tools across multiple blockchains.
This comprehensive overview explores the core functionalities, trading mechanisms, supported markets, and unique features that define the 1inch ecosystem — all while maintaining full decentralization and non-custodial security.
What Is 1inch Exchange?
1inch Exchange is more than just a DEX — it's a multi-protocol DeFi aggregator built on three foundational pillars:
- Aggregation Protocol
- Limit Order Protocol
- Liquidity Protocol
These protocols work in tandem to deliver superior trade execution, passive income opportunities, and enhanced liquidity management for users across Ethereum, Polygon, BNB Chain, and other EVM-compatible networks.
As a non-custodial platform, 1inch ensures users retain full control over their funds. There’s no requirement for KYC verification, making it accessible to anyone with a Web3 wallet like MetaMask or Trust Wallet.

How 1inch Exchange Works: Key Protocols Explained
Aggregation Protocol – Best Rates Across DEXs
The heart of 1inch’s value proposition lies in its Aggregation Protocol, which scans dozens of decentralized exchanges — including Uniswap, SushiSwap, Curve, and Balancer — to find the most favorable token swap rates. Instead of routing trades through a single DEX, 1inch splits large orders across multiple platforms to minimize slippage and maximize output.
This intelligent routing ensures traders receive better prices than they would on any standalone exchange.
Limit Order Protocol – Precision Trading Without Custody
Unlike traditional limit orders that require fund custody, 1inch’s Limit Order Protocol uses smart contracts to enable trustless limit orders directly from your wallet. Users can place two types of orders:
- Limit Orders: Execute when the market reaches a specified price.
- RFQ (Request for Quote) Orders: Facilitated by professional market makers for high-value trades with tighter spreads and reduced slippage.
This protocol supports advanced trading strategies while preserving decentralization and user control.
Liquidity Protocol – Earn Yield Through Deep Pools
The Liquidity Protocol powers 1inch’s automated market maker (AMM) model, allowing users to provide liquidity and earn trading fees. By depositing token pairs into designated pools, liquidity providers (LPs) contribute to deeper markets and receive a share of transaction revenues.
Additionally, LPs can take advantage of 1inch Earn, a yield-generating service that leverages derivative instruments to boost annual percentage yields (APY), offering competitive returns compared to other DeFi platforms.
Unique Features That Set 1inch Apart
Fusion Mode: Feeless & Front-Run Resistant Swaps
One of 1inch’s standout innovations is Fusion Mode, a transaction mechanism that enables feeless swaps by batching user operations off-chain before settlement. This not only reduces gas costs but also protects traders from sandwich attacks — a common form of front-running in DeFi.
By participating in Fusion Mode, users trade securely and economically across integrated DEXs without exposing their transactions to predatory bots.
1inch DeFi Wallet – All-in-One Crypto Management
The 1inch Wallet (formerly known as Wallet by 1inch) is a non-custodial mobile wallet that allows users to:
- Buy, store, and swap tokens
- Stake assets for passive income
- Interact with dApps securely
- Access cross-chain functionality
For MetaMask users, the RabbitHole feature adds an extra layer of protection by rerouting sensitive transactions through secure channels, effectively mitigating the risk of wallet exploitation during swaps.
1inch API – Powering DeFi Integrations
Developers and institutional traders can leverage the 1inch API, a robust routing algorithm that aggregates liquidity from top DeFi protocols. This tool enables wallets, exchanges, and fintech applications to offer optimized token swaps without building their own aggregation logic.
The API supports real-time pricing, multi-chain operations, and customizable slippage controls — making it ideal for integrating DeFi capabilities into third-party platforms.
Tokens Behind the Platform: 1INCH and CHI
1INCH Token – Utility and Governance
Launched in December 2020, the 1INCH token serves dual roles within the ecosystem:
- Governance: Token holders can vote on protocol upgrades, fee models, and treasury allocations.
- Utility: Used for staking, fee discounts, and participation in governance-mining programs.
With a fixed supply cap, 1INCH incentivizes long-term community engagement and decentralized decision-making.
CHI Gas Token – Reduce Transaction Costs
The CHI token is a gas optimization tool designed specifically for the Ethereum network. When gas prices are low, users can mint CHI; when prices rise, they can burn CHI to offset transaction fees.
Using CHI effectively reduces overall trading costs — especially during periods of high network congestion — giving traders greater control over their expenses.
Trading Mechanics: No Spot Market, But Smarter Alternatives
While 1inch doesn’t offer a traditional spot market like centralized exchanges, it provides equally powerful — if not superior — alternatives:
- Token Swaps: Instant exchanges using aggregated liquidity.
- Limit Orders: Set future execution prices with zero counterparty risk.
- Peer-to-Peer Trading: Enabled via RFQ orders with professional market makers.
This approach aligns with DeFi principles: permissionless access, self-custody, and transparent execution.
Fees and Cost Efficiency
One of 1inch’s major advantages is its transparent fee structure:
- No deposit fees
- No withdrawal fees
- No platform exchange fees
Users only pay standard network gas fees and minor protocol fees charged by underlying DEXs. These costs can be further minimized using CHI tokens or by executing trades during off-peak hours.

The Team Behind 1inch Exchange
Founded in 2019 by Sergey Kunz and Anton Bukov, both seasoned software engineers with extensive experience in blockchain and enterprise systems, 1inch was born out of a need to solve inefficiencies in early DEX trading.
- Sergey Kunz previously led Bulktrade as CEO and worked with global brands like Porsche in software development roles.
- Anton Bukov contributed to blockchain projects like NEAR Protocol as a senior smart contract engineer and brings deep expertise in consensus mechanisms and decentralized systems.
Their technical background laid the foundation for Mooniswap — an innovative AMM launched in 2020 that introduced time-delayed price updates to reduce arbitrage losses for liquidity providers.
Ecosystem Growth: Grants and Innovation
To foster innovation within the DeFi space, 1inch launched the 1inch Grant Program, which funds developers and teams building tools, integrations, and educational resources for the 1inch Network. This initiative strengthens community involvement and drives long-term platform sustainability.
