Shutter Network vs MEV Blocker

How Shutter Network and MEV Blocker differ on type, protection, rebates and what they’re built for.

Shutter NetworkMEV Blocker
TypeEncrypted mempoolPrivate RPC
How it worksTransactions are encrypted with threshold cryptography and only decrypted after they’re committed to a block, hiding intent from searchers entirely. Bringing encrypted txs to Ethereum PBS with Primev.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 againstFrontrunning & censorship via threshold encryptionFrontrunning & sandwiching on any Ethereum dApp
RebatesN/A — prevention by encryptionUp to 90% of back-run value, auto-deposited

Best forApps that need intent-hiding + censorship resistanceEveryday wallets that want rebates

Shutter Network

  • Strongest intent-hiding (encryption, not just privacy)
  • Also resists censorship
  • Protocol-level approach via PBS
  • Not a simple wallet RPC yet
  • Adds latency from encrypt/decrypt

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 Shutter Network for apps that need intent-hiding + censorship resistance; pick MEV Blocker for everyday wallets that want rebates.
