How 1inch Fusion and Flashbots Protect differ on type, protection, rebates and what they’re built for.
| 1inch Fusion | Flashbots Protect | |
|---|---|---|
| Type | Intent DEX | Private RPC |
| How it works | You sign an order (intent) rather than broadcasting a public tx; resolvers compete to execute it on-chain, absorbing MEV risk and often improving your price. Failed orders cost no gas. | Sends your transaction privately to the Flashbots block-building auction. MEV-Share selectively shares hints so searchers can bid to back-run it, sharing the profit with you. |
| Protects against | Sandwiching/frontrunning via off-chain intents | Frontrunning, sandwiching & failed-tx reverts |
| Rebates | Better execution price instead of a cash rebate | 90% of back-run MEV + gas-fee refunds |
| Chains | Ethereum + major L2s | Ethereum |
| Setup | Swap on 1inch with Fusion mode | Add RPC rpc.flashbots.net to your wallet |
| Best for | Swappers who want gasless, protected trades | The conservative, battle-tested default |
Pick 1inch Fusion for swappers who want gasless, protected trades; pick Flashbots Protect for the conservative, battle-tested default.
