# 1inch

1inch is a DEX aggregator across EVM-compatible blockchains (Ethereum, Arbitrum, BSC, Avalanche, Polygon, Optimism, and others). Like Jupiter but for Ethereum's ecosystem — it finds the best swap routes across all available decentralized exchanges.

Multi-chain EVM, with support including: Ethereum, BNB Chain (BSC), Polygon, Arbitrum, Optimism, Avalanche, Gnosis, Base, zkSync Era, Linea, Unichain, Sonic, Solana. [Visit the 1inch website for the full list](https://1inch.com/).

## What it's good for

- **Multi-chain swaps** — Trade on any EVM-compatible blockchain from one interface.
- **Best prices** — Splits your trade across multiple DEXs to get the most favorable rate.
- **No KYC** — Connect your wallet and trade directly. No email or ID required.

## How it works

1. Connect your EVM-compatible wallet (like MetaMask).
2. Tell your agent which tokens to swap and how much.
3. 1inch scans all major EVM DEXs, finds the best route, and executes the trade through its routing smart contract.

## Fees

- Trading fees depend on the DEX routes 1inch chooses — you get the best available rate.
- Network (gas) fees vary by chain: Ethereum mainnet can be expensive; layer-2 chains like Arbitrum and Optimism are much cheaper.
- 1inch itself does not charge an extra fee for the aggregation service.

## Best use case

Pick 1inch if you trade across multiple EVM-compatible blockchains (Ethereum, Arbitrum, BSC, Avalanche, etc.) and want the best swap prices without checking each DEX manually.

## Limitations

- **No leverage** — 1inch only supports spot token swaps. For leveraged trading, use Hyperliquid.
- **Perp DEXs on EVM are limited** — 1inch focuses on spot swaps. While some perpetual venues exist on EVM chains, they're not as mature as Hyperliquid's dedicated perp market.
