Same-Slot LUCID

Same-slot encrypted execution for Ethereum's LUCID encrypted mempool (EIP-8184).

Conditional commitments let builders decrypt and include protected transactions in the same slot — no extra latency, no compromises.

Key Properties

• Leaderless — Block builders commit in parallel, no need to know the auction winner
• Slot-time agnostic — Works at 12s, 6s, or 3s slots without degradation
• Incentive-complete — Builders pay for keys, key publishers release because they're compensated
• Zero user fee — Builders bear the cost; users can set key_publication_fee = 0

Deploy

Static HTML. Deploy to any hosting:

# Vercel
