What is 1inch?
1inch is a DEX aggregator and a network of DeFi protocols that splits swaps across many exchanges. Its help center lists 19 supported networks, including Solana. In the default swap mode, resolvers pay gas, and the API provider keeps any price surplus. The 1INCH token, issued by the 1inch Foundation, is used for DAO voting.
How 1inch works
The default Swap mode runs on 1inch Fusion.
You sign an order, and resolvers bid for it in a Dutch auction: the rate starts high and drops until a resolver accepts it and fills the trade. The resolver pays gas and bundles transactions before they reach the mempool, which gives front-running protection. Each order has a time window, and if no resolver takes it, it expires and you resubmit. Classic mode is the original aggregation protocol: you pay gas yourself, but the trade executes almost immediately near the quote.
Cross-chain swaps use Fusion+. The winning resolver deposits your tokens into an escrow on the source chain and the matching tokens into an escrow on the destination chain, both locked by one secret hash plus a safety deposit. Once the relayer verifies both escrows, the secret is revealed and each side is released. If a swap stalls, a recovery phase returns assets after a time lock. The help center says to keep the browser tab open until a cross-chain order completes.
How to start with 1inch
- You do not need an account, KYC or a deposit.
- Set up the 1inch Wallet or another supported wallet, fund it with tokens plus some of the chain's native asset, connect it to the 1inch dApp and swap.
- The first Fusion swap still needs native tokens to approve the token contract.
- The help center lists 17 EVM networks, including Ethereum, Base, Arbitrum, zkSync Era, Monad, HyperEVM and Robinhood Chain, plus Solana.
- On Arc, gas is paid in USDC.
- 1inch says its products are available in the US, but some products, features or assets may not be available in some US states.
- Wallets are screened through TRM Labs, and a flagged address is blocked from the interface.
- Using a VPN to hide your location breaches the Terms of Use.
1inch fees and limits
In Swap mode you usually pay no gas, because resolvers cover it. Swaps from native tokens or involving Solana, and some very small swaps routed through the aggregator, charge you gas. In Pro (Classic) mode you pay gas directly. If the final price beats the quote, the surplus is kept by the API provider, 1inch Business. Some swaps also carry infrastructure fees set at the API layer. In Swap mode and for limit orders the taker covers them; on aggregator-routed swaps you do.
Risks to know before using 1inch
- 1inch is non-custodial, and its help center lists audits by OpenZeppelin, Consensys Diligence, SlowMist, Certik, Hacken and five other firms.
- It still states that its services are provided as is and that smart contract interactions carry risk.
- A Fusion order can expire unfilled if no resolver accepts it in time, and closing the tab during a Fusion+ swap can cancel the order.
- Access limits are a real factor for US users: some products or assets are restricted in some states, and addresses flagged by TRM Labs for sanctions or stolen funds are blocked automatically.
- In the UAE, access is limited to viewing and exiting positions.
- Support staff cannot grant access to users located in a restricted territory.
