How to Swap ETH to USDT on 1inch
Swapping ETH for USDT on 1inch is a straightforward process designed for both newcomers and seasoned users:
- Enter Swap Details: Open the 1inch dApp and input the amount of ETH you'd like to exchange in the "You pay" field. The platform will automatically calculate the estimated USDT output.
- Use Auto Settings (Recommended): For a hassle-free experience, stick with the default auto settings, which optimize slippage tolerance and route selection.
- Execute the Swap: Click “Permit and Swap,” then confirm the transaction in your wallet. If it's your first time swapping a token, you may need to approve it separately.
For advanced users, customizing slippage, expiration time, or choosing between Classic and Fusion modes gives greater control over trade parameters.

Understanding 1inch Fusion: Smarter Swaps, Better Protection
At the heart of 1inch’s innovation lies Fusion, a protocol upgrade that redefines how decentralized swaps work.
MEV Protection
Maximal Extractable Value (MEV) is a major concern in DeFi, where bots exploit transaction visibility to profit at users’ expense. Fusion combats this by bundling user orders and matching them directly with professional resolvers—trusted market makers—who execute trades off-chain. This prevents public exposure of your transaction, effectively eliminating front-running risks.
Gasless Transactions
One of the biggest barriers for new users is needing native tokens (like ETH) just to pay gas fees. With Fusion, resolvers cover the network costs, enabling true gasless swaps. You only need the token you're swapping—no extra coins required.
Smart Order Execution
Fusion uses dynamic pricing logic to fulfill orders efficiently. Users can set price ranges and time limits, allowing resolvers to compete for order fulfillment. This competitive mechanism often results in better-than-market rates.
Optimal Efficiency Through Dutch Auctions
Fusion employs a Dutch auction model: large orders are split into smaller chunks and filled progressively as prices adjust downward. This minimizes price impact and increases the likelihood of executing above average market rates—maximizing value for users.

What Is Fusion+? The Future of Cross-Chain Swaps
Fusion+ builds on the success of Fusion by introducing native support for cross-chain swaps—all without sacrificing self-custody or security.
With Fusion+, you can seamlessly swap ETH on Ethereum for USDT on Polygon, Arbitrum, or any other supported chain—without relying on bridges or third-party custodians. Transactions remain fully under your control, protected from MEV, and executed without gas fees on the destination chain.
Supported networks include:
- Ethereum
- Arbitrum
- Avalanche
- Aurora
- BNB Chain
- Base
- Gnosis
- Optimism
- Polygon
- zkSync
If a token isn’t listed, you can manually add it using its contract address—giving you access to thousands of ERC-20 and equivalent tokens across ecosystems.
Frequently Asked Questions
Q: What is the difference between Classic mode and Fusion mode?
A: Classic mode routes swaps through traditional DEX aggregators and requires gas fees. Fusion mode offers MEV protection, gasless swaps, and smarter execution via resolver networks.
Q: Do I need ETH for gas when using Fusion?
A: No. In Fusion mode, resolvers cover the gas costs—so you can swap any token without holding native chain assets.
Q: Is my private key safe during a Fusion+ swap?
A: Yes. All Fusion+ transactions are self-custodial. You retain full control of your wallet and assets throughout the process.
Q: Can I swap ETH to USDT across different blockchains?
A: Absolutely. Fusion+ enables direct cross-chain swaps—e.g., swap ETH on Ethereum for USDT on Base or Optimism—without intermediaries.
Q: How does 1inch find the best rates?
A: 1inch aggregates liquidity from hundreds of sources across DEXs and RFQ systems, analyzing thousands of routes in real-time to deliver optimal pricing.
Q: What is MEV, and why does it matter?
A: MEV (Maximal Extractable Value) refers to profits miners or bots make by reordering transactions. It can lead to failed trades or worse prices. Fusion neutralizes this risk entirely.
What Is ETH?
Ethereum (ETH) is the second-largest cryptocurrency by market capitalization and powers the world’s most widely used smart contract platform. It serves as the primary fuel for decentralized applications (dApps), including DeFi protocols like 1inch.
When swapping tokens on Ethereum-based platforms, ETH is typically used to pay transaction fees (gas). It also enables interaction with ERC-20 tokens like USDT, making it essential for most crypto activities within the ecosystem.
While ETH is required for network operations, innovations like Fusion reduce dependency on holding ETH solely for gas—opening doors for broader accessibility.
