Description

Phase 1 review of the Private Transaction Broadcasting approach and the cards it links, for the encrypted mempool approach cycle.

  • Approach: new Private Relay sub-approach, now the default for orders that must reach the chain. Encrypted Mempools ratings aligned with the threshold pattern, plus the Ethereum L1 status (LUCID, FOCIL) and three open questions.
  • Threshold-Encrypted Mempool: cr from high to medium. The sender stays visible and builders can refuse ciphertexts; it reaches high once inclusion lists carry sealed transactions. Keys are released once the ordering is committed, not after finality.
  • Other patterns: FOCIL and Private Transaction Broadcasting updated; Shutter repository and SUAVE fixes; Network Anonymity re-reviewed, date only.
  • Vendors: Shutter and Flashbots brought up to date; SUAVE archived.
  • Links: five trading use cases, the Trading domain and the glossary.

The cr change is the main judgement call; happy to discuss.

- **Networks:** live on Gnosis Chain; Ethereum integration planned
- **Networks:** Gnosis Chain mainnet (encrypted mempool, 7 keypers with a threshold of 4); Shutter API on Gnosis Chain and Chiado
- **Ethereum:** an out-of-protocol proof of concept with Primev's mev-commit was announced for the Hoodi testnet in December 2025 (3-of-5 keypers, builders commit before keys are released). The mainnet launch had not happened as of September 2026.
- **Enshrinement:** Shutter authored [EIP-8105](https://eips.ethereum.org/EIPS/eip-8105) (Draft), an enshrined encrypted mempool. Its bid to headline the Hegotá upgrade was withdrawn in February 2026 in favour of LUCID ([EIP-8184](https://eips.ethereum.org/EIPS/eip-8184)), which the team now supports for the upgrade after Hegotá.

the february 2026 shutter post backs lucid as a Hegotá headliner. the september 2026 brainbot update says only that the team decided to pursue LUCID with validator allowlisted proposers. neither source names the upgrade after hegotá.

suggestion: drop the fork claim.

The Brainbot update set “Have an EM EIP ready to propose as I* Headliner” as a goal, so I kept the sentence, but updated it with the source.

Wrt to everything else, agreed on all your comments, see 6d5bf17.
