description: Shutter Network provides encrypted-mempool infrastructure that prevents MEV extraction and front-running by encrypting transactions until they are included in blocks, using threshold cryptography for decryption. It is live on Gnosis Chain, with Ethereum integration planned.

# Shutter Network – Encrypted Mempool & MEV Protection

## Fits with patterns

* [Pre-trade Privacy](/patterns/pattern-pretrade-privacy-encryption/): encrypted mempool with threshold decryption
* [Private Broadcasting](/approaches/approach-private-broadcasting/): intent signaling protection

## Not a substitute for

* Post-execution privacy (transactions are visible after inclusion)
* Cross-chain MEV protection
* Complex intent expression (focuses on transaction-level protection)

## Architecture

Shutter uses threshold encryption: users encrypt transactions with a shared public key; a network of validators collectively decrypts them after block inclusion; searchers cannot see transaction content during the vulnerable mempool phase; ordering protection prevents front-running while maintaining transaction validity.

## Enterprise demand and use cases

* Encrypted mempool preventing MEV extraction during broadcasting
* Threshold decryption with no single point of failure
* Censorship resistance through distributed key management

## Technical details

* **Networks:** live on Gnosis Chain; Ethereum integration planned
* **Compatibility:** works with standard Ethereum transactions
* **Validator requirements:** requires a network of threshold key holders
* **Developer experience:** minimal changes to existing dApp integration

## Strengths

* Proven solution with mainnet deployment
* Strong cryptographic foundations (threshold encryption)
* Minimal impact on existing Ethereum workflows
* Effective MEV prevention during the critical mempool phase

## Risks and open questions

* Limited to supported networks (Gnosis Chain currently)
* Adds latency due to the threshold decryption process
* Requires coordination among threshold key holders
* No protection against MEV after transaction execution
