MEV Blocker vs 1inch Fusion

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

MEV Blocker1inch Fusion
TypePrivate RPCIntent DEX
How it worksRoutes 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.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.
