Decentralized finance (DeFi) continues to reshape how users interact with digital assets, and at the heart of this transformation lies 1Inch Exchange—a powerful tool that optimizes crypto trading across multiple platforms. Launched in 2019, 1Inch has evolved from a simple DEX aggregator into a full-fledged DeFi ecosystem, complete with its own governance token and innovative liquidity protocols. In this comprehensive guide, we’ll explore what makes 1Inch unique, how it works, and how you can use it to maximize your trading efficiency.
What Is 1Inch Exchange?
1Inch is a decentralized exchange (DEX) aggregator designed to help users get the best possible rates when swapping cryptocurrencies. Unlike traditional exchanges that operate on a single liquidity pool, 1Inch scans dozens of DEXs simultaneously—including Uniswap, SushiSwap, and Curve—to find the most cost-effective trading route.
Founded by Sergej Kunz and Anton Bukov in 2019, 1Inch addresses a key challenge in DeFi: fragmented liquidity. With prices and gas fees varying widely across platforms, executing a trade on just one exchange often means overpaying. 1Inch solves this by splitting large trades across multiple platforms, minimizing slippage and reducing overall transaction costs.

This cross-platform optimization makes 1Inch especially valuable for traders dealing with high-value swaps or less liquid tokens.
How Does 1Inch Work?
At its core, 1Inch uses an advanced algorithm called the Pathfinder Engine, which evaluates over 33 different liquidity sources in real time. When you initiate a token swap, the system analyzes:
- Current market prices
- Gas fees on various networks
- Available liquidity depth
- Expected price slippage
For example, if you want to exchange USDT for WBTC, 1Inch might route part of your trade through Uniswap, another portion via SushiSwap, and a final leg through Curve—all within a single transaction. This process ensures you receive the maximum output while paying the lowest possible fees.
Additionally, 1Inch supports limit orders and gas-efficient batch transactions, further enhancing user control and cost savings.
The platform operates non-custodially, meaning your funds never leave your wallet during a trade. All transactions are executed directly on-chain using smart contracts, ensuring full transparency and security.
The 1Inch Liquidity Protocol (Formerly Mooniswap)
In August 2020, 1Inch launched its own automated market maker (AMM) protocol called Mooniswap, later rebranded as the 1Inch Liquidity Protocol. This innovation was designed to reduce impermanent loss—a common issue for liquidity providers on traditional AMMs like Uniswap.
Mooniswap introduced a time-weighted fee model that discourages short-term arbitrage bots from exploiting price discrepancies between exchanges. By delaying fee distribution based on time delays in arbitrage opportunities, it levels the playing field for regular liquidity providers.
While the protocol isn’t as widely used as Uniswap or PancakeSwap, it remains an important part of 1Inch’s ecosystem, showcasing the team’s commitment to solving real DeFi challenges.
How to Use 1Inch Exchange: Step-by-Step
Using 1Inch is straightforward—even for beginners. Follow these steps to start swapping tokens securely:
Step 1: Access the Platform
Visit the official 1Inch Exchange interface through any modern web browser.
Step 2: Connect Your Wallet
Click “Connect Wallet” at the top right corner. Choose from supported wallets like MetaMask, WalletConnect, Trust Wallet, or hardware options like Ledger.
Once selected, confirm the connection in your wallet app.
Step 3: Select Tokens to Swap
Choose the token you want to send (e.g., USDT) and the one you wish to receive (e.g., DAI). Make sure you have enough native currency (like ETH or MATIC) to cover gas fees.
Step 4: Approve Token Spending
Before trading, you must approve 1Inch to access your tokens. You can choose between:
- Unlock: Grants access for a specific amount
- Unlock Infinite: Allows unlimited spending (saves gas if trading frequently)
Confirm the approval transaction in your wallet.
Step 5: Execute the Swap
Click “Swap” and review the estimated output, fees, and slippage tolerance. Adjust settings if needed, then confirm the trade.
Within seconds, your new tokens will appear in your wallet.

The 1INCH Token: Governance and Airdrops
One of the most exciting moments in 1Inch’s history came on December 25, 2020, when the team launched the native $1INCH token with a surprise airdrop. Early users received free tokens simply for interacting with the platform—a move that generated massive community excitement.
The $1INCH token serves as a governance token, allowing holders to vote on proposals related to protocol upgrades, fee structures, and treasury management. With a total supply capped at 1.5 billion tokens, distribution occurs over four years through:
- User incentives
- Team allocations
- Investor releases
- Community rewards
A second major airdrop followed in early 2021, distributing 15 million additional tokens to a broader group of DeFi participants—including users of Uniswap and other integrated protocols.
Today, $1INCH is listed on major exchanges such as Binance, Huobi Global, and decentralized platforms like SushiSwap.
