Decentralized Finance (DeFi) has revolutionized how users interact with financial services, and at the heart of this transformation lies efficient trading infrastructure. One platform that stands out in optimizing DeFi trades is 1inch.exchange. By aggregating liquidity across multiple decentralized exchanges (DEXs), 1inch ensures users receive the best possible rates with minimal slippage and optimized gas usage. This article dives into how 1inch works, its role in yield farming, gas optimization strategies, and why it’s become a cornerstone tool for DeFi users.
What Is 1inch.exchange?
1inch.exchange is a leading DEX aggregator designed to streamline token swaps across the fragmented DeFi landscape. Instead of manually checking prices on Uniswap, Curve, Balancer, or Kyber, users can rely on 1inch to scan multiple liquidity sources simultaneously and route trades through the most cost-effective paths.
The platform integrates major DEXs such as:
- Uniswap
- Curve.fi
- Balancer
- Aave
- Bancor
- Oasis
- Airswap
- dForce Swap
- 0x Protocol
It also taps into private market makers, enhancing price discovery beyond public pools.
When you initiate a swap on 1inch, the protocol often splits your trade across several exchanges—a technique known as split routing—to minimize price impact and maximize output. For example, converting aDAI (Aave’s interest-bearing DAI) back to DAI might involve partial execution on Uniswap and Balancer, depending on real-time liquidity and pricing.

This seamless aggregation makes 1inch function like a "Swiss Army knife" for DeFi—compact, versatile, and essential.
Non-Custodial & User-Controlled
As a non-custodial platform, 1inch never holds user funds. All transactions occur directly from your wallet (e.g., MetaMask, WalletConnect). However, to enable repeated interactions without excessive gas costs, 1inch supports unlimited token approvals, known as “infinity unlock.”
While convenient, unlimited approvals carry security risks—if a compromised contract accesses your approved token, it could drain your balance. As an alternative, users may opt for per-transaction approvals, which are safer but incur higher gas fees due to repeated authorization.
Additionally, users can customize their experience by disabling specific DEXs they don’t wish to route through—offering greater control over where their trades execute.
The Role of 1inch in Yield Farming
Yield farming involves deploying idle crypto assets into lending protocols or liquidity pools to earn returns. While platforms like Aave or Compound offer straightforward interest accrual (e.g., swapping DAI for aDAI), more complex strategies require frequent asset conversions.
Imagine a yield farmer holding LINK who wants to deposit into Aave to earn yield in aDAI. Without 1inch, this would involve:
- Finding a DEX with strong LINK/DAI liquidity.
- Swapping LINK for DAI.
- Transferring DAI to Aave.
- Converting DAI to aDAI.
Each step risks suboptimal pricing and accumulates gas costs—especially problematic during network congestion.
With 1inch, this entire process condenses into one click. The platform automatically finds the best route from LINK → DAI → aDAI, minimizing slippage and ensuring efficiency.
This capability becomes even more valuable when switching between yield-generating assets. For instance, moving from aDAI on Aave to aSUSD (Synthetix’s interest-bearing stablecoin) requires multiple hops:
- aDAI → DAI
- DAI → SUSD
- SUSD → aSUSD
Again, 1inch handles this multi-leg swap seamlessly—though at a cost.
Navigating Ethereum Gas Fees with CHI GasToken
High gas fees on Ethereum remain one of the biggest hurdles in DeFi. Complex swaps on 1inch—especially those involving multiple hops—can cost over $30 in gas alone.
For example, converting 50 aDAI to ~50 aSUSD may require interacting with three different contracts, each demanding gas payment. During peak network usage, these costs become prohibitive for average users.
To mitigate this, 1inch introduced CHI GasToken, an innovative solution that helps users save on transaction costs during high-fee periods.
How CHI Works
GasTokens like CHI allow users to “store” gas when prices are low and “spend” it later when fees spike. Here's how:
- When gas is cheap, users mint CHI tokens by executing storage-heavy (but low-value) transactions.
- Later, when gas is expensive, burning CHI offsets part of the transaction cost by refunding gas used during cleanup operations.
Using CHI effectively can reduce total swap costs by up to 30–50%, making high-frequency trading more viable.

While newer Layer 2 solutions (like Arbitrum or Optimism) offer cheaper alternatives, CHI remains a powerful tool for Ethereum-native traders seeking efficiency without leaving the mainnet.
The Founders Behind 1inch
Launched in June 2019 at the ETHNewYork Hackathon, 1inch was created by experienced developers Sergej Kunz and Anton Bukov.
- Sergej Kunz brings decades of software engineering experience, including roles at Porsche in Germany.
- Anton Bukov previously worked on iOS/macOS development and contributed to cross-chain interoperability between NEAR and Ethereum before co-founding 1inch.
Their background in algorithmic trading and arbitrage bots gave them unique insight into DeFi inefficiencies—inspiring the creation of a smart routing engine that could outperform manual trading.
Beyond product development, the team is known for publishing detailed DeFi vulnerability reports, highlighting security flaws in platforms like Balancer and Bancor—further establishing their credibility in the ecosystem.
Key Platform Metrics and User Insights
Since its inception, 1inch has demonstrated consistent utility within the DeFi space:
- Daily Users: Peaks around 730 daily active users (reached June 24, 2020), averaging around 300.
- Transaction Size Distribution: Most trades range between $500 and $8,000, indicating strong adoption among retail investors.
- Large Transactions: Fewer than 100 trades have exceeded $1 million—suggesting whales either use custom setups or split large orders to avoid slippage.
This pattern reflects both the platform’s accessibility for everyday users and its strategic use by sophisticated traders managing large positions discreetly.
FAQ: Frequently Asked Questions
Q: Is 1inch safe to use?
A: Yes. As a non-custodial platform, you retain full control of your funds. However, always review token approvals and revoke unused ones using tools like Revoke.cash.
Q: Does 1inch support networks other than Ethereum?
A: Yes. 1inch now operates on multiple chains including BNB Chain, Polygon, Arbitrum, Optimism, and Avalanche—reducing reliance on Ethereum’s congested network.
Q: How does 1inch find the best price?
A: It uses advanced algorithms to analyze real-time liquidity across integrated DEXs and splits trades optimally to reduce slippage and improve output.
Q: Can I use 1inch without paying high gas fees?
A: Yes. Consider using Layer 2 networks supported by 1inch or leverage CHI GasToken during peak times to lower costs.
Q: Why choose 1inch over Uniswap?
A: While Uniswap offers simplicity, 1inch typically provides better exchange rates by comparing multiple sources—ideal for larger or complex swaps.
Q: Do I need to trust the 1inch team with my assets?
A: No. 1inch is non-custodial—you sign all transactions locally in your wallet. The platform merely suggests optimal routes.
Final Thoughts: The Future of DEX Aggregators
Despite the dominance of major DEXs like Uniswap and Curve, liquidity fragmentation persists. Different pools offer varying depths for token pairs (e.g., Uniswap excels in LINK/ETH; Kyber may lead in SNX/ETH), forcing traders to hunt for value manually—unless they use an aggregator like 1inch.
Looking ahead, as more users demand seamless experiences, front-end usability and routing intelligence will determine competitive advantage. Even if one DEX becomes a “liquidity black hole,” diversification across protocols will likely continue—ensuring aggregators remain relevant.
For now, 1inch remains a leader in DeFi routing, combining technical innovation with practical utility. Whether you're a yield farmer optimizing returns or a trader seeking optimal pricing, integrating 1inch into your workflow enhances efficiency and reduces friction in the evolving DeFi economy.
