1inch Fusion vs MEV Blocker

How 1inch Fusion and MEV Blocker differ on type, protection, rebates and what they’re built for.

1inch FusionMEV Blocker
TypeIntent DEXPrivate RPC
How it worksYou 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.Routes your transaction through a searcher auction instead of the public mempool; searchers bid for the right to back-run it and rebate up to 90% of the profit to you automatically.
Protects againstSandwiching/frontrunning via off-chain intentsFrontrunning & sandwiching on any Ethereum dApp
RebatesBetter execution price instead of a cash rebateUp to 90% of back-run value, auto-deposited

1inch Fusion

  • Gasless swaps (no gas on unfilled orders)
  • MEV-protected by design
  • Often better price via resolver competition
  • Only for swaps via 1inch, not arbitrary txs
  • Execution depends on resolver competition

MEV Blocker

  • Largest adoption (4.5M+ wallets)
  • Up to 90% back-run rebates, auto-paid
  • Protects on any dApp once set as RPC
  • Ethereum mainnet only
  • Rebate size depends on searcher competition

Bottom line

Pick 1inch Fusion for swappers who want gasless, protected trades; pick MEV Blocker for everyday wallets that want rebates.
