EIP-8105: A new design for Ethereum’s encrypted mempool
Sponsored Content
While EIP-8105 significantly limits MEV exposure, earlier providers in the block retain a limited ability to extract MEV from later transactions by selectively revealing or withholding their decryption keys. The proposal attempts to mitigate this by letting key providers designate other trusted providers and ordering transactions according to the resulting key provider trust graph.
Encrypted Mempools and Ethereum’s Roadmap
Encrypted mempools are becoming an increasingly important part of Ethereum’s roadmap, as the ecosystem looks for protocol-level ways to reduce harmful MEV. While EIP-8105 is no longer being positioned as one of the headliners for the first 2027 hard fork, it remains an open draft, and its ideas continue to inform the broader effort to prepare a leading encrypted-mempool proposal for the upgrade.
