Shutter Network

Shutter Network is an open-source project that aims to prevent frontrunning and malicious MEV on Ethereum by using a threshold cryptography-based distributed key generation (DKG) protocol.
A Shutter transaction is a transaction protected from frontrunning in the target smart contract system. It therefore passes through a sequence of stages before it is executed.
A Shutter transaction flow:
  1. 1.
    Created and encrypted in the user's wallet;
  2. 2.
    Sent to the batcher contract as a standard Ethereum transaction;
  3. 3.
    Picked up and decrypted by the keypers;
  4. 4.
    Sent to the executor contract, and
  5. 5.
    Forwarded to the target contract.
