DAO voters have long demanded permanent private voting. It’s now on Shutter’s roadmap. This post shares the architecture and a working POC showing how we’re extending threshold-encrypted voting with ElGamal-based homomorphic tallying - so votes are counted in the encrypted state and remain private.

CZ recently called for a dark pool-style perp DEX - but there’s no need to build a full FHE dark pool. Shutter API for Shielded Trading offers a scalable solution today using threshold encryption to stop malicious MEV across DEXs, OTC desks, and derivatives.

On-chain governance has gone mainstream - but every public vote is a signal that can be bought and coerced. There remains a huge privacy gap in how decisions are made. Shutter aims to help close it with on-chain Shielded Voting.

Kleros, the decentralized “court” of Web3, is upgrading its juror voting system to be more private and user-friendly. By integrating Shutter API’s Shielded Voting into Kleros Court V2, jurors will be able to cast secret votes that remain hidden until the case is closed - without the hassle of

Decent DAO’s Shutter API upgrade aims to restore voting confidence across DAOs.

The uncomfortable truth about trust-based MEV protections is that they are effective—until they fail.

Many of the riskiest dApps on Ethereum today share the same fatal flaw: they rely on a broken and unprotected transaction system. Whether it's NFT drops, token launches, Web3 games, or betting platforms, unprotected dApps are getting hijacked by bots, insiders, and high-rollers.

To showcase our recently launched Shutter API, we built Shutter Predict, a simple mini dApp that allows you to make a prediction.

We are excited to announce the release of "The Road Towards a Distributed Encrypted Mempool on Ethereum," a white paper that outlines an essential advancement in Ethereum's transaction infrastructure. This research is now available on the Ethresearch forum and presents a structured roadmap for implementing threshold
