front running and
malicious MEV
on Ethereum

Shutter is an open-source project that aims to prevent front running on Ethereum by using a threshold cryptography-based distributed key generation (DKG) protocol.

Shutter is a project to address the challenge of malicious MEV on Ethereum as well as other information asymmetries in distributed systems. Shutter aims to protect users from such exploitation by employing a distributed key generation mechanism, ensuring fair and secure transactions on Ethereum and Layer 2 solutions like rollups and sidechains.

What Is MEV?

Maximal Extractable Value or MEV is the revenue the block producer (e.g. validator, miner, sequencer) can extract via front running, injecting, reordering or censoring transactions. The MEV extracted in 2020 alone was worth more than $314M — and that is only a lower bound.

How Shutter works

Shutter uses a threshold cryptography-based distributed key generation (DKG) protocol.

The mechanism used by Shutter can be implemented into various layers. The first instantiation we built is a simple drop-in solution for smart contracts at the application level, which is gas efficient and doesn’t require L1/L2 protocol changes.

Shutter DAO

A DAO has always been at the core of the vision of Shutter's value proposition. It is an integral part of how the system is designed to function, especially concerning the Keyper Set Selection Process and the Set Management.

We invite the Shutter Network community to actively participate in shaping a DAO, ensuring that it represents the collective aspirations and needs. This approach fosters a strong sense of ownership and commitment among community members, which is vital for any DAO's success.

Introducing the Shutter Network Genesis Allocations

Phase 1 of a Shutter DAO focuses on laying a solid groundwork and establishing effective governance. During this initial phase, a comprehensive governance framework is created, ensuring a fair distribution of the initial token allocation and introducing non-transferable tokens.

The Genesis Allocations are smart contracts deployed on the Ethereum blockchain. An allocation contains a list of addresses as they have been deployed in the and the amount of claimable Shutter Tokens (e.g., SHU) per address in the form of a Merkle root.

Rollup as a Service

Rollups can now start integrating an encrypted mempool using threshold encryption for malicious MEV protection and real-time censorship resistance.

Conduit allows anyone to deploy a rollup through our self-serve platform in a matter of minutes, no code required.


Gelato is web3’s decentralized backend empowering builders to create augmented smart contracts that are automated, gasless & off-chain aware.


Launch your application-specific Rollup with the Zeeve Web3 Platform.


Instant private zk-rollups, with all the tools.


AltLayer is an open and decentralised interlayer for rollups.


Caldera makes it easy to launch performant, customizable Arbitrum Orbit and OP Stack rollups. No code required.



Accessibility, base layer neutrality and censorship resistance form the basis of the value proposition of public blockchains like Gnosis Chain and Ethereum and we believe an encrypted mempool is a key requisite and major milestone towards ensuring those fundamental properties.

Gnosis Chain is one of the first Ethereum sidechains and has stayed true to its values.

Gnosis Chain


Shutter Governance, a tool for governance platforms to introduce shielded voting for their users. It uses threshold encryption and is designed to fix issues with misbehavior, voter apathy, and voting incentive systems.

Snapshot is a voting platform that allows DAOs, DeFi protocols, or NFT communities to vote easily and without gas fees.
