1inch Review 2026: How the DEX Aggregator Routes Swaps

1inch is a decentralised exchange aggregator. Instead of being one trading venue, it checks pricing across many DEXs and routes a swap to get a better rate. Users trade from their own wallet, so the protocol does not take custody of funds.

Beyond the swap interface, the project offers the 1inch Wallet, which sources describe as self-custodial, and a native token, 1INCH, which is widely listed on exchanges. Recent price quotes in the sources put it at roughly nine US cents.

One review site reports support for 13 or more chains. User reviews praise the number of integrated exchanges and the ease of searching tokens by contract address. Another review says beginners can use it, but some DeFi knowledge helps because users must understand wallets and gas fees.

The project's homepage was not available to confirm current product details, so check the live app for the supported chains and features.

A DEX is an exchange run by smart contracts, where traders swap against pools of tokens. Each DEX has its own pools and prices, so the same trade can get different rates in different places.

1inch aggregates those sources. Its Pathfinder routing reads real-time pricing from many exchanges, and it can split a single order across several pools to get a better combined rate. You see one quote and sign one transaction.

Fusion is a further swap mode that one review site says adds MEV protection. MEV refers to bots that reorder or insert transactions around a trade to take value. Throughout, the user's wallet stays in control of the funds.

The sources reviewed do not publish a fee schedule. In general, an aggregator swap costs the network gas fee plus the price impact of the route, and the app shows the expected output before you confirm.

The effective cost varies by chain, trade size and liquidity. Check the quote screen for the exact amount and any protocol or interface charge before signing.

1inch is non-custodial, so there is no exchange account holding your balance. The main risks are smart-contract risk, since a trade touches the aggregator and the underlying DEXs, and user risk such as phishing, fake sites and over-broad token approvals. Use only the official site and revoke approvals you no longer need.

The sources reviewed do not detail audits, bug bounties, team information or past incidents, so readers should check the project's own documentation for current audit reports. Crypto assets are volatile and DeFi tools carry no deposit insurance. Rules on trading and on token access differ by country, so confirm what applies where you live.

1inch is for traders and DeFi users who already hold a self-custodial wallet and want better swap pricing across many decentralised exchanges. It also suits people who trade on several chains and prefer one interface. Anyone who wants fiat on-ramps, customer support and account recovery may find a centralised exchange simpler.
