How does 1inch Swap work?

1inch Swap connects your trade to resolvers who compete to fill your order at the best available rate. In Fusion and Fusion+ modes, resolvers may pull liquidity from DEXs, CEXs, and private pools. Classic swaps route directly through the 1inch Aggregation Protocol, which splits orders across multiple liquidity sources to improve pricing and reduce slippage.

What is the benefit of Fusion or Fusion+ on 1inch?

Fusion allows gasless, intent-based swaps where third-party resolvers compete to fill your order at the best rate. You don’t need native tokens for gas, and your trade is protected from MEV attacks. Fusion+ extends this functionality to cross-chain swaps without bridges, using escrow contracts for secure settlement.

Can I use 1inch without holding ETH or other native tokens?

Yes, Fusion mode allows you to swap tokens without holding ETH, MATIC, BNB, or other native assets. Resolvers cover all gas costs and execute the trade on your behalf. This is especially useful for new wallets or users with only stablecoins.

What risks or limitations should I be aware of?

Fusion swaps may take longer to execute due to the auction mechanism and resolver participation. Limit orders can remain unfilled if the target price is not met or liquidity is low. Classic swaps still require gas fees and expose trades to MEV unless protected manually.
