We're excited to announce that Shutter and Primev are partnering to bring the first threshold encrypted mempool to Ethereum's out-of-protocol transaction supply chain, PBS (Proposer-Builder Separation). This integration targets the long standing issue of front running, sandwich attacks, and real-time censorship across the PBS pathway, which

We’re excited to announce that Shutter and Snapshot are partnering to bring Permanent Shielded Voting to all DAOs using Snapshot. This new system will use a form of linear threshold-homomorphic encryption (specifically ElGamal) in combination with zero-knowledge proofs, ensuring that every individual vote remains permanently private while voting results

What if your AI could launch time-locked encrypted workflows with just a few prompts? That’s now possible with today’s release of the testnet alpha of Shutter MCP, powered by Shutter API. With Shutter MCP, your AI can set up and run: * Sealed-bid request for proposals * Sealed bug bounties

Encrypted mempools dramatically reduce censorship and malicious MEV, but face limitations such as potential collusion, rigid setups, and added latency. In this article, we’ll explore advanced, deployable cryptographic primitives - beyond FHE and MPC - that can address these limitations.

Glamsterdam is Ethereum’s next big upgrade - and a chance to dramatically improve decentralization and censorship resistance. Shutter supports prioritizing EIP-7732 (ePBS) and EIP-7805 (FOCIL), with encrypted mempools and silent threshold encryption proposed as powerful future implementations.

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.

We appreciate the thoughtful perspectives of the analysts at a16z Crypto on the limitations and potential of encrypted mempools in addressing MEV (Maximal Extractable Value). Their recent blog post raises valid points and highlights genuine challenges. That said, we see several key issues differently and offer a perspective informed by

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.

Censorship resistance and decentralization are core to public blockchains, ensuring open, permissionless access. But in today’s world of bots, AI, and memecoin mania, these founding principles are too often forgotten.
