The decentralized exchange (DEX) landscape remains highly fragmented—and this fragmentation is precisely where platforms like 1inch.exchange thrive. As yield farming and complex token swaps become standard in the DeFi ecosystem, users increasingly demand efficiency, cost-effectiveness, and seamless execution. 1inch.exchange has evolved from a simple liquidity aggregator into an essential Swiss Army knife for DeFi traders, offering smart routing, gas optimization, and access to multiple DEXs in one interface.
This article dives deep into what makes 1inch.exchange a cornerstone of modern DeFi trading, how it solves real-world user challenges, and why it continues to rank among the top DeFi tools by product-market fit.
What Is 1inch.exchange?
1inch.exchange is a decentralized exchange (DEX) aggregator designed to optimize token swaps across multiple liquidity sources. Instead of limiting users to a single DEX’s order book or pool depth, 1inch scans dozens of platforms—including Uniswap, Curve, Balancer, Aave, Kyber, and Oasis—to find the most efficient trade path with minimal slippage and optimal pricing.
Unlike traditional exchanges, 1inch does not host its own liquidity. Instead, it acts as a smart routing engine, splitting large trades across various protocols to ensure users get the best possible rate. For example, if you're swapping aDAI for DAI, 1inch might route part of your trade through Uniswap and another through Balancer—dynamically adjusting based on real-time price differences.

This multi-source approach is especially valuable in volatile markets where small price discrepancies between exchanges can significantly impact profitability.
How Does It Work?
When you initiate a swap on 1inch, the platform performs thousands of calculations in milliseconds to determine the optimal combination of DEXs for your transaction. This process, known as split trading, allows users to avoid high slippage on large orders that would otherwise deplete a single liquidity pool.
Additionally, 1inch supports non-custodial trading, meaning your funds never leave your wallet. The platform interacts directly with smart contracts across different protocols but never holds user assets—ensuring full control and security at all times.
Another key feature is infinite approval (or “infinite unlock”)—a mechanism that allows users to grant one-time permission for a token to be used across multiple transactions. While this reduces gas costs over time (since you’re not re-approving each trade), it also introduces potential security risks if a compromised contract gains access to your tokens. As such, advanced users may prefer per-transaction approvals for higher-risk assets.
You can also customize which DEXs to include or exclude from routing—giving traders full transparency and control over their execution paths.
The Role of 1inch in Yield Farming
Yield farming involves deploying idle crypto assets into lending or liquidity pools to earn passive income. While platforms like Aave and Compound automate interest accrual, getting your assets into the right pool often requires several manual swaps—especially when dealing with non-stablecoins.
Let’s say you hold LINK and want to farm yields on Aave by converting it into aDAI (the interest-bearing version of DAI). Without 1inch, this would involve:
- Finding a DEX with strong LINK/DAI liquidity
- Executing the swap
- Transferring DAI to Aave
- Depositing into the protocol to receive aDAI
Each step incurs gas fees and exposes you to price slippage. With 1inch, however, this entire workflow can be completed in a single transaction—reducing both cost and execution risk.

Moreover, 1inch integrates with yield-tracking platforms like LoanScan and DeFi Rate, allowing users to compare interest rates across protocols and act quickly when opportunities arise.
Tackling Ethereum Gas Fees: CHI GasToken
One of the biggest pain points in using 1inch—or any Ethereum-based DeFi app—is high gas fees. Complex multi-hop trades can easily exceed $30 in network costs during peak congestion.
To mitigate this, 1inch introduced CHI GasToken, an innovative solution that helps users save on transaction fees during high-gas periods.
What Is CHI GasToken?
GasTokens allow users to "store" gas when prices are low and "spend" it when prices spike. CHI is 1inch’s proprietary implementation of this concept. When gas prices drop below a certain threshold, the system automatically mints CHI tokens by performing minimal operations. Later, when gas prices rise, these tokens are burned to offset part of the transaction cost.
For frequent DeFi traders, using CHI can result in significant savings—especially during network congestion. According to data from Dune Analytics, users who leverage GasToken mechanisms reduce their average transaction costs by up to 40% on 1inch.
While newer Layer 2 solutions and alternative blockchains are reducing reliance on Ethereum’s mainnet, CHI remains a powerful tool for optimizing on-chain efficiency today.
Behind the Scenes: The 1inch Team
Founded in June 2019 by Sergej Kunz and Anton Bukov at ETHNewYork Hackathon, 1inch emerged from a deep understanding of DeFi inefficiencies. Both founders are seasoned software engineers with decades of combined experience in enterprise systems and blockchain development.
- Sergej Kunz previously worked at Porsche Digital, bringing enterprise-grade engineering rigor to DeFi.
- Anton Bukov contributed to cross-chain interoperability projects before focusing full-time on 1inch.
The team has gained recognition not only for building a leading aggregation platform but also for publishing detailed DeFi vulnerability reports, helping secure protocols like Balancer and Bancor against exploits.
Their ongoing participation in hackathons reflects a commitment to innovation—continuously refining UX, exploring new arbitrage strategies, and enhancing platform security.
Platform Metrics and User Insights
As of the latest data:
- Daily active users: ~300 (peaked at 730 in mid-2020)
- Transaction volume distribution: Majority of trades range between $500–$8,000
- Large transactions (> $1M): Fewer than 100 recorded
These figures highlight that 1inch primarily serves retail and active DeFi traders, rather than institutional whales. However, the prevalence of smaller trades may also reflect whales splitting large orders to minimize slippage—a common strategy in fragmented liquidity environments.
The platform aggregates liquidity from over a dozen sources, including major AMMs and private market makers, ensuring competitive pricing even for less common token pairs.
Why Fragmentation Fuels Aggregators
Despite growth in DEX volume, liquidity remains scattered across platforms:
- Uniswap: Strong in ETH-paired assets like LINK/ETH
- Curve: Optimized for stablecoin swaps (e.g., DAI/USDC)
- Balancer: Supports custom-weighted pools
- Kyber: Offers dynamic pricing models
Manually checking each platform for the best rate is impractical. 1inch eliminates this friction by consolidating data and executing optimized trades instantly.
Looking ahead, while there’s speculation about a single “liquidity black hole” dominating DeFi (e.g., a future super-DEX), the diversity of use cases—ranging from stablecoins to volatile altcoins—suggests continued fragmentation. That means aggregators will remain critical infrastructure.
Frequently Asked Questions (FAQ)
Q: Is 1inch.exchange safe to use?
Yes. 1inch is non-custodial—your funds stay in your wallet. However, always review contract permissions (like infinite approvals) and use trusted wallets like MetaMask or WalletConnect.
Q: Does 1inch support networks other than Ethereum?
Yes. In addition to Ethereum, 1inch supports Binance Smart Chain, Polygon, Arbitrum, Optimism, and others—helping users avoid high gas fees via Layer 2s and sidechains.
Q: How does 1inch make money?
1inch earns revenue through a small fee (typically 0.3%) on profitable trades—a portion of which goes back to 1INCH token stakers. Users can opt out of paying fees if they don’t mind slower execution.
Q: Can I earn rewards on 1inch?
Yes. By holding or staking the native $1INCH token, users can earn protocol incentives, governance rights, and fee rebates.
Q: What’s the difference between Uniswap and 1inch?
Uniswap is a standalone DEX with its own liquidity pools. 1inch is an aggregator that uses Uniswap (and many others) as data sources to find better prices across multiple platforms.
Q: How accurate are the price estimates on 1inch?
Price estimates factor in slippage tolerance and real-time pool depths. However, extreme volatility may cause slight deviations between quote and final execution price.
