What Is 1inch Fusion?
At the heart of 1inch’s innovation lies Fusion, a groundbreaking mechanism that enhances swap security and efficiency. Unlike traditional swaps exposed to miner extractable value (MEV) attacks—like front-running or sandwich attacks—Fusion protects users through a unique bundling system.
MEV Protection
Fusion shields your trades by grouping multiple swap orders into bundles executed directly with professional market makers called resolvers. Because individual transactions aren’t visible on the public mempool, malicious actors cannot exploit them, effectively eliminating MEV risks.
Gasless Swaps
One of the most user-friendly features of Fusion is gasless swapping. You don’t need native gas tokens (like ETH) in your wallet to complete a transaction. Instead, resolvers cover the gas fees, making it easier for new users to interact with DeFi without prior funding.
Smart Execution & Dutch Auction Model
Fusion uses a Dutch auction model for optimal execution:
- Orders are split into smaller parts.
- Resolvers compete to fulfill them at progressively better prices.
- Swaps execute partially over time until fully completed or rate limits are hit.
This method often results in trades executed above average market rates—maximizing returns for users.

Understanding USDC and ETH
What Is USDC?
USD Coin (USDC) is a stablecoin pegged 1:1 to the US dollar, issued by Circle and backed by reserve assets. It’s widely used for trading, lending, and transferring value across blockchains with minimal volatility.
What Is ETH?
Ethereum (ETH) is the native cryptocurrency of the Ethereum blockchain, the world’s leading smart contract platform. As the second-largest digital asset by market cap, ETH powers decentralized applications (dApps), NFTs, DeFi protocols, and more.
ETH is required to pay transaction fees (gas) on the Ethereum network and is essential for participating in most Web3 activities.
