Our MethodologyOverview
1inch is a decentralized-exchange aggregator: it compares routes across multiple liquidity sources and can split a swap between sources. Its own help center describes three relevant execution choices. Classic submits an on-chain transaction, while limit orders wait for stated conditions. Fusion uses competing resolvers that cover the associated gas for an eligible order. The execution mode can change the route and cost. No mode guarantees an outcome or removes token, contract, liquidity, approval or execution risk.
Current network coverage
The 1inch help center lists Arbitrum, Avalanche, BNB Chain, Base, Ethereum, Gnosis and Linea. The EVM list also includes Optimism, Polygon, Robinhood Chain, Sonic, Unichain and zkSync Era. It lists Solana separately as a non-EVM network. The page network table covers the EVM entries because the data model requires an EVM-style numeric chain ID. The current 1inch network guide marks Fantom, Kaia and Aurora as deprecated.
How to assess a quote
Check the selected network, token contract addresses, route, amount received, price impact, approval scope and wallet prompt before signing. Classic-mode costs may include network gas and fees charged by underlying liquidity sources. For Fusion, 1inch says resolvers compete to fill the order and cover its associated gas. Availability and execution still depend on the order and resolver market. The review is desk research based on the official documents in the source list. It is not an execution test.

Pros & Cons of 1inch
Pros of 1inch
- ✓Aggregation routing can split a swap across multiple liquidity sources
- ✓Fusion orders are filled by competing resolvers that cover the associated gas
- ✓Classic, Fusion and limit-order modes serve different execution needs
- ✓The current help center lists 13 EVM networks and Solana
Cons of 1inch

- ✗Fusion execution depends on resolver participation and order conditions
- ✗Token, approval and smart-contract risks remain
1inch documents an aggregation protocol that compares liquidity sources and can split one transaction across multiple sources. The resulting route and quote depend on the tokens, amount, network and liquidity available at that moment, so a favorable outcome is not guaranteed.
In Fusion mode, the user signs an order and resolvers compete to fill it. 1inch says the resolver covers the associated gas, so the user does not need the network native token for that eligible order. Execution and availability still depend on resolver participation and the quoted terms.
No. A 1inch swap can interact with aggregation contracts, tokens and underlying liquidity sources. Review the route, token addresses, approvals and wallet prompt before signing, and use the official 1inch domain.
Alternatives include other aggregators and direct decentralized exchanges. Compare the final amount received, price impact, route, network cost and contract approvals in each live quote. No venue is always cheaper.
Costs vary by route and execution mode. Classic swaps can include network gas and fees from underlying liquidity sources. For eligible Fusion orders, 1inch says resolvers cover the associated gas. The confirmation quote is the relevant cost disclosure for a specific order.
