SShutter Network

A different defense — encrypts your transaction until it’s included, so bots can’t even read your intent.

Encrypted mempoolBy ShutterToken: SHUSince 2022
Type
Encrypted mempool
How it works
Transactions 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.
Protects against
Frontrunning & censorship via threshold encryption
Rebates
N/A — prevention by encryption
Chains
Ethereum (PBS-bound), Gnosis Chain
Setup
Used via integrating apps / keypers

* Dated snapshot (provider docs & public reports, 2026), not a live figure.

Best for

Apps that need intent-hiding + censorship resistance.

Strengths

  • Strongest intent-hiding (encryption, not just privacy)
  • Also resists censorship
  • Protocol-level approach via PBS

Trade-offs

  • Not a simple wallet RPC yet
  • Adds latency from encrypt/decrypt
  • Still rolling out on Ethereum mainnet
