1inch Network (1INCH) is a DEX aggregator that splits token swaps across multiple liquidity sources using the Pathfinder algorithm to find the optimal rate — and its Fusion Mode lets users swap without paying gas by routing through a competitive network of professional market makers called Resolvers who stake 1INCH to fill orders via Dutch auction.
1INCH is the protocol’s governance token, used for 1inch DAO voting and for Resolver staking (Unicorn Power). Founded in 2019 at the ETHNew York hackathon by Sergej Kunz and Anton Bukov, 1inch has become one of the most widely integrated DeFi swap layers by cumulative volume.

How It Works
- Pathfinder algorithm — When a user requests a swap, 1inch’s Pathfinder algorithm runs in real time across all integrated liquidity sources (Uniswap v2/v3, SushiSwap, Curve, Balancer, DODO, Synthetix, Bancor, Kyber, and dozens more) to compute the optimal split routing — dividing the swap across sources and routes to minimize slippage.
- Split routing — For large trades, splitting across multiple AMMs reduces price impact (slippage). A $1M USDC→ETH swap routing entirely through one pool might move the price significantly; splitting across 5 different pools minimizes total slippage.
- 1inch Limit Order Protocol — Beyond market swaps, 1inch offers a limit order protocol allowing users to set target prices for swaps. Orders are filled by resolvers when the price condition is met, without gas from the user (resolver pays gas).
- Fusion Mode — 1inch’s Fusion swap mode uses Dutch auction order mechanics: the swap creates an on-chain order at the user’s intended rate, which gradually improves (auction down the rate) until a Resolver (institutional market maker who stakes 1INCH) accepts and executes it. Users get swaps without paying gas; Resolvers earn the spread between the Dutch auction rate and the actual market rate.
- 1INCH staking (Unicorn Power) — Staking 1INCH grants “Unicorn Power” — a governance weight and eligibility for the Resolver program (Resolvers must stake 1INCH as collateral).
- Multichain — 1inch is available on Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, Gnosis Chain, Base, and others.

Use Cases
- Best-rate token swaps — Users always get the best aggregated price across all integrated DEXs.
- Gas-free swaps (Fusion) — Swap without holding ETH for gas; Resolvers cover gas in exchange for spread.
- Limit orders — Place off-chain limit orders executed by Resolvers when price target is met.
- DeFi trading infrastructure — Many DeFi routing aggregator products (portfolio managers, wallets) integrate 1inch’s API as their default routing engine.
- DAO governance — 1INCH holders vote on protocol fee structures, aggregator integrations, and development priorities.
History
- 2019-05 — Sergej Kunz and Anton Bukov build 1inch.exchange at the ETHNew York hackathon — a proof-of-concept DEX aggregator pulling rates from multiple AMMs. The project wins the hackathon. They decide to build it as a full product.
- 2019-09 — 1inch opens a public version, allowing trades across Uniswap, Kyber, and Bancor. It immediately provides better rates than any single exchange for most pairs. Early DeFi power users adopt it quickly.
- 2020 — DeFi summer. 1inch processes billions in monthly volume as the DEX landscape fragments across Uniswap v2, SushiSwap, and many others. Aggregation becomes more valuable as sources multiply.
- 2020-12-25 — 1INCH token launches via a retroactive airdrop to all wallets that had used 1inch before December 24, 2020. This Christmas airdrop is one of the largest retroactive token distributions — wallets received hundreds to tens of thousands of dollars in 1INCH depending on usage history. The DAO simultaneously launches.
- 2021 — 1inch raises $175M Series B from Amber Group, Fenbushi Capital, and others. The DST Global investment brings significant institutional participation. 1inch expands to Polygon, BSC, and other chains. Monthly volume regularly exceeds $10B.
- 2021-12 — 1inch Limit Order Protocol v2 launches, enabling advanced conditional orders and stop-loss functionality on-chain.
- 2022 — 1inch Fusion Mode launches — the conceptually distinct “intent-based” swap model where users post intents (desired swaps) and competing Resolvers fill them, similar to Flashbots-style MEV redistribution in user favor. This model influences other aggregators and becomes an industry design pattern.
- 2023 — 1inch integrates with many more sources. Fusion Mode matures. The 1inch Wallet (mobile) launches for iOS and Android offering built-in Fusion swaps. 1inch reports cumulative all-time volume exceeding $200B+.
- 2024 — 1inch continues as the dominant DEX aggregator by volume on multiple chains. Competition from CoW Protocol, Paraswap, and on-chain intent-based protocols intensifies. The Fusion architecture continues to evolve with improved Resolver competition mechanics.
Common Misconceptions
“1inch is a DEX — it has its own liquidity pools.”
1inch is primarily an aggregator, not a DEX with its own liquidity. It routes user trades through other protocols’ liquidity pools (Uniswap, Curve, etc.). 1inch does have a small liquidity pool product (1inch Liquidity Protocol, a Uniswap v2 fork), but the aggregator is the core product.
“Fusion Mode is free — it has no cost.”
Fusion Mode eliminates gas costs for users but is not economically free. Resolvers take a spread between the Dutch auction execution price and the market rate as their compensation. In effect, users pay a spread rather than gas. For large trades, this is often still a better deal than paying gas for a non-optimized swap.
Social Media Sentiment
- r/CryptoCurrency / r/ethfinance: 1inch is treated as a go-to practical tool for DeFi power users. Posts recommend it for large swaps where routing quality matters. The 1INCH token’s poor price performance relative to the protocol’s utility is a recurring frustration.
- X/Twitter: Sergej Kunz and Anton Bukov are respected DeFi figures. The 2020 Christmas airdrop is often cited as one of the most generous retroactive distributions in DeFi history. Ongoing debate compares 1inch Fusion to CoW Protocol and UniswapX on MEV protection and execution quality.
- Discord (1inch DAO): Technically focused governance discussions around Resolver requirements, fee switch parameters, and chain expansion. Developer community is active; retail speculation is minimal.
