Decentralized finance (DeFi) continues to reshape how individuals interact with digital assets, and at the heart of this transformation lies a powerful tool: the decentralized exchange aggregator. Among the most prominent platforms in this space is 1inch, a leading DEX aggregator designed to optimize trading efficiency across multiple decentralized exchanges (DEXs). For beginners navigating the complex world of DeFi, understanding 1inch can significantly enhance trading outcomes by securing better prices, reducing slippage, and simplifying access to liquidity.
This guide offers a clear, structured overview of 1inch, covering its functionality, core features, tokenomics, and advantages over standalone DEXs—helping new users make informed decisions in their crypto journey.
What Is a Decentralized Exchange (DEX)?
Before diving into 1inch, it’s essential to understand decentralized exchanges. Unlike centralized platforms like traditional crypto exchanges, DEXs operate without intermediaries. They enable peer-to-peer trading directly from users’ wallets using smart contracts, eliminating the need for third-party custody of funds.
DEXs offer greater privacy, security, and user control. Traders retain ownership of their assets at all times and only need to connect their digital wallets—such as MetaMask or WalletConnect—to begin trading. Popular examples include Uniswap, SushiSwap, and PancakeSwap.
However, one major challenge with individual DEXs is fragmented liquidity. Prices and available trading pairs can vary significantly across platforms, leading to inefficiencies and higher slippage for users.

Introducing 1inch: The Smart DEX Aggregator
1inch solves the liquidity fragmentation problem by acting as a decentralized exchange aggregator. Instead of manually checking multiple DEXs for the best rates, users can leverage 1inch to automatically scan dozens of platforms and route trades through the most optimal paths.
Think of 1inch as a smart travel agent for crypto trades—it compares flight prices across airlines to get you the cheapest option, except here, it's comparing token swap rates across DEXs in real time.
By pulling liquidity from sources like Uniswap, SushiSwap, Balancer, and 0x, 1inch ensures users receive the best possible price with minimal fees and slippage. This seamless aggregation allows traders to execute high-efficiency swaps without needing deep technical knowledge or constant market monitoring.
The Founders Behind 1inch
1inch was created in May 2019 by Sergey Kunz and Anton Bukov during an ETHGlobal hackathon. Both developers had strong technical backgrounds—Kunz previously worked as a software engineer at Porsche, while Bukov contributed to the NEAR Protocol. Their shared vision was to build a solution that addressed inefficiencies in early DeFi trading.
Their prototype quickly gained traction, leading to a $12 million funding round in 2020 from top-tier investors including Pantera Capital, Binance Labs, Galaxy Digital, and ParaFi Capital. This support accelerated development and paved the way for the launch of the 1INCH governance token in December 2020.
As part of a community-first approach, early users were rewarded through an airdrop, receiving 1INCH tokens if they had used the platform prior to the token launch.
How Does 1inch Work?
At its core, 1inch uses advanced algorithms and smart contract logic to deliver superior trading performance. Here are the key components that power its ecosystem:
Aggregation Protocol
The backbone of 1inch is its Aggregation Protocol, which splits a single trade across multiple DEXs to achieve the best effective rate. For example, instead of executing an entire ETH-to-USDC swap on one exchange where slippage might be high, 1inch divides the trade between Uniswap, SushiSwap, and Curve—minimizing price impact and maximizing output.
This process happens instantly and transparently, allowing users to benefit from deep liquidity without managing multiple platform interactions.
Liquidity Protocol (Formerly Mooniswap)
To further enhance efficiency, 1inch developed its own Liquidity Protocol, originally known as Mooniswap. This protocol enables users to become liquidity providers (LPs) by depositing asset pairs into shared pools.
In return, LPs earn trading fees generated from swaps executed against their liquidity. Additionally, they receive LP tokens that can be staked or used elsewhere in DeFi ecosystems.
What sets this protocol apart is its resistance to front-running attacks, thanks to a mechanism called virtual rates.
Virtual Rates: Fighting Front-Running
Front-running occurs when malicious actors exploit public mempools to see pending transactions and place higher-fee trades ahead of them for profit. 1inch combats this using virtual rates, which dynamically adjust pricing curves in liquidity pools to make front-running unprofitable—protecting both traders and liquidity providers.
Limit Order Protocol
Beyond simple swaps, 1inch supports limit orders, giving users more control over their trades. With this feature, traders can set conditions such as:
- Stop-loss orders: Automatically sell when a token drops below a certain price.
- Trailing stop orders: Lock in profits as prices rise, then exit if momentum reverses.
- Take-profit orders: Execute a sale once a target price is reached.
These tools bring traditional finance strategies into DeFi, offering greater flexibility and risk management.

Advantages of 1inch Over Standalone DEXs
While individual DEXs play a crucial role in DeFi, they often suffer from:
- Low liquidity on less popular pairs
- High slippage during large trades
- Inconsistent pricing across networks
1inch addresses these issues by:
- Aggregating deep liquidity from numerous sources
- Reducing slippage through intelligent order splitting
- Offering better execution prices than any single DEX could provide alone
This makes it especially valuable for larger trades or volatile market conditions.
The 1INCH Token: Governance and Utility
The 1INCH token is an ERC-20 utility and governance token running on Ethereum. It empowers holders to participate in platform decisions such as:
- Protocol upgrades
- Fee structure changes
- Treasury allocations
Launched in December 2020, the token has since been listed on major exchanges and integrated across various DeFi applications. A portion of transaction fees generated on the platform may also be used to buy back and burn 1INCH tokens, potentially increasing scarcity over time.
Holders can stake their tokens to earn rewards or delegate voting power to community representatives.
Frequently Asked Questions (FAQ)
Q: Is 1inch safe to use?
A: Yes. As a non-custodial platform, 1inch never holds your funds. You retain full control of your wallet at all times. Always verify you're on the official site and approve transactions carefully.
Q: Can I use 1inch on blockchains other than Ethereum?
A: Yes. While originally built on Ethereum, 1inch now supports multiple blockchains including BNB Chain, Polygon, Arbitrum, Optimism, and others—reducing gas costs and increasing accessibility.
Q: Do I need to pay to use 1inch?
A: There are no direct platform fees. However, users pay standard network gas fees for transactions. Some advanced features may include small service fees used for protocol development.
Q: How does 1inch find the best prices?
A: It uses real-time data from dozens of DEXs and applies optimization algorithms to split trades across multiple venues for maximum output and minimum slippage.
Q: Can I earn passive income with 1inch?
A: Yes. By providing liquidity through the Liquidity Protocol or staking 1INCH tokens, users can earn rewards in the form of fees or additional tokens.
Q: What makes 1inch different from other aggregators?
A: Its combination of smart routing, anti-front-running mechanics (via virtual rates), and native limit order functionality sets it apart as one of the most feature-rich DEX aggregators available.
