Decentralized finance (DeFi) has reshaped how users interact with digital assets, and at the forefront of this evolution stands 1inch, a powerful decentralized exchange (DEX) aggregator. In this comprehensive review, we’ll dive deep into how 1inch works, its key features, tokenomics, security aspects, and whether investing in the 1INCH token is a smart move in 2025.
Whether you're new to DeFi or an experienced trader, understanding platforms like 1inch can significantly enhance your crypto journey—offering better rates, reduced slippage, and seamless cross-DEX trading.
What Is 1inch?
1inch is a leading decentralized exchange aggregator built on the Ethereum blockchain. Unlike traditional DEXs that host liquidity directly, 1inch scans multiple exchanges—including Uniswap, SushiSwap, Curve, and Balancer—to find the most efficient trading routes for users.
Founded in 2019 by Russian developers Sergej Kunz and Anton Bukov after winning a hackathon at the Ethereum Developer Conference, 1inch quickly gained traction by solving one of DeFi’s biggest pain points: fragmented liquidity.
By pooling data from over 50 decentralized and centralized liquidity sources, 1inch ensures users get the best possible price when swapping tokens—without needing to visit each platform individually.

How Does 1inch Work?
At its core, 1inch uses advanced algorithms to optimize every trade. When you initiate a swap—say, from USDT to DAI—the platform doesn’t just check one exchange. Instead, it splits your order across multiple DEXs to minimize slippage and reduce costs.
This process is powered by the 1inch Pathfinder, an intelligent routing engine that analyzes real-time liquidity, price impact, and gas fees across networks. It can even route trades through intermediate tokens if doing so results in a better final rate.
For example:
- You want to swap 10,000 USDT → DAI
Instead of executing entirely on Uniswap (where large trades suffer high slippage), 1inch might:
- Route 6,000 USDT via Curve
- Send 3,000 via Balancer
- Use 1,000 via SushiSwap with a temporary hop through ETH
All of this happens seamlessly in a single transaction, saving you money and time.
Additionally, users can adjust slippage tolerance and set custom transaction speeds depending on network congestion.
Key Benefits of Using 1inch
✅ Best Price Execution
Thanks to its aggregation model, 1inch consistently delivers superior pricing compared to single-exchange platforms.
✅ No Platform Fees
1inch doesn’t charge additional fees on swaps. You only pay the standard blockchain gas fees associated with your wallet’s network.
✅ Non-Custodial & Permissionless
There’s no KYC or account creation required. Simply connect a compatible wallet like MetaMask or WalletConnect and start trading instantly.
✅ High Liquidity Access
By tapping into dozens of liquidity pools, even large trades can be executed smoothly with minimal market impact.
✅ Governance Through $1INCH Token
Token holders participate in protocol decisions via decentralized governance (DAO), voting on upgrades, fee structures, and ecosystem development.
Challenges and Risks
While 1inch offers many advantages, it’s important to consider potential drawbacks:
❌ No Fiat On-Ramps
The platform supports only cryptocurrency transactions. If you’re looking to buy crypto with USD or EUR, you’ll need to use a centralized exchange first.
❌ Smart Contract Risk
As with all DeFi protocols, there’s inherent risk in interacting with smart contracts. Although audited, vulnerabilities could be exploited in extreme scenarios.
❌ "Infinity Unlock" Security Debate
The option to permanently approve token spending can save gas but increases risk if your wallet is compromised. Always use temporary approvals unless frequently trading.
The 1inch Pathfinder: Smarter Routing, Better Returns
The Pathfinder API is one of 1inch’s standout innovations. Introduced in version 2.0, it dynamically calculates optimal swap paths using real-time market depth analysis.
It considers:
- Liquidity availability across pools
- Price impact of large orders
- Transaction cost (gas)
- Intermediate token efficiency
This means smaller spreads, lower slippage, and higher net returns—especially valuable during volatile market conditions.
Developers can also integrate Pathfinder into dApps, expanding its utility beyond the main interface.
Understanding 1inch Gas Optimization Features
Although 1inch doesn’t charge extra fees, users still face Ethereum gas costs. To help mitigate this:
🔹 CHI Gas Token (Legacy)
Previously used to bundle transactions and reduce gas during peak times. While less relevant post-EIP-1559, it showcased early innovation in cost-saving mechanisms.
🔹 Partial Fill & Slippage Control
Enable “partial fill” to execute parts of your trade immediately rather than waiting for full execution—ideal for illiquid pairs.

The 1INCH Token: Utility and Distribution
The $1INCH token is an ERC-20 governance token central to the protocol’s decentralization.
Key Details:
- Total Supply: 1.5 billion
- Initial Airdrops: Distributed in December 2020 and February 2021 to early users and Uniswap traders
Allocation:
- 30% to community (airdrops, liquidity mining)

Even without minimum holding requirements, active participation strengthens decentralization and long-term sustainability.
Airdrops and Liquidity Mining Programs
1inch has historically rewarded early adopters through targeted airdrops:
- First drop: 90 million tokens to users who traded before September 2020
- Second drop: 6 million tokens to active Uniswap users not yet using 1inch
Ongoing liquidity mining programs incentivize users to provide liquidity to specific pools, earning additional $1INCH rewards.
While future airdrops aren't guaranteed, maintaining engagement with the protocol increases eligibility chances for new campaigns.
