About 1inch

1inch Network is the leading multi-chain DEX aggregator, routing trades across 300+ liquidity sources to find optimal rates. Founded by Sergej Kunz and Anton Bukov after winning the ETHNewYork 2019 hackathon, 1inch has facilitated over $400 billion in trading volume. The Pathfinder algorithm finds the most efficient swap routes, often splitting trades across multiple DEXs. Fusion mode enables gasless swaps by having professional 'resolvers' compete for order execution, providing MEV protection. The 1inch Wallet offers a complete self-custody solution with built-in swaps and staking.

How 1inch Works

1inch doesn't have its own liquidity pools - instead, it aggregates liquidity from 300+ DEXs across 8 chains to find you the best price. The Pathfinder algorithm analyzes all possible routes, often splitting your trade across multiple DEXs for optimal execution. For example, swapping 100 ETH might route 60% through Uniswap, 30% through Curve, and 10% through Balancer. Fusion mode goes further by letting professional 'resolvers' compete to fill your order, providing MEV protection and gasless swaps - you sign a message and resolvers pay the gas.

Frequently Asked Questions

How does 1inch make money if there are no fees?
1inch takes a small spread on positive slippage - if your swap executes better than expected, 1inch keeps part of the difference. In Fusion mode, resolvers pay for gas and compete on pricing, with 1inch taking a cut from resolvers.
What is Fusion mode?
Fusion mode lets you swap without paying gas. You sign a message authorizing the swap, and professional 'resolvers' compete to execute your order. They pay the gas and profit from optimizing execution. You get MEV protection since your order isn't in the public mempool.
Is 1inch better than using Uniswap directly?
Often yes, especially for large trades. 1inch routes through Uniswap when it has the best price, but might find better rates elsewhere or by splitting trades. For small swaps, the difference may be minimal after gas costs.
Does 1inch work on all chains?
1inch supports Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Gnosis, and Base. Each chain aggregates local DEXs - for example, on Arbitrum it routes through Uniswap, Camelot, SushiSwap, etc.
