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
- Adoption*
- Live on Gnosis Chain · Ethereum PBS rollout in progress
- By
- Shutter
* 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
