Key-Withholding Optionality as a Structural MEV Risk in EIP-8105 and LUCID: Analysis, Quantification, and Mitigation ProposalsKey withholding isn’t just a bug — it’s a risk-free MEV option.
LUCID/EIP-8105 only burn ∼0.1 ETH to withhold, but a publisher can make 5 ETH by suppressing your tx. That’s 4.9 ETH profit to withhold. Builders take risk. Key publishers get a monopoly option: reveal if it helps, withhold if not.
Fix it with: 1. Gas-scaled bonds, 2. Locked reveal times, 3. On-chain withholding attribution.
Also: LUCID’s per-key PTC vote is easier to bribe, and FRAME should be primary for wallet adoption.
Bottom line: Fixed fees can’t outprice a dynamic option. Harden penalties before launch or you just swap builder MEV for key-publisher MEV.
