Facet Co-Founder Pitches EIP-8182 for Ethereum Hegota Upgrade

Tom Lehman, co-founder of Layer 2 network Facet, pitched EIP-8182 for inclusion in Ethereum's Hegota upgrade on Friday, proposing a protocol-managed shielded pool to enable native private ETH and ERC-20 transfers on the base layer. The proposal, first introduced in March, addresses a structural flaw in existing privacy solutions where new pools cannot attract users without anonymity, yet cannot provide meaningful anonymity without critical mass. Hegota, Ethereum's planned H2 2026 upgrade, combines execution-layer client "Bogota" and consensus-layer client "Heze." EIP-8182 is one of three related proposals targeting privacy infrastructure for the upgrade.

EIP-8182 Technical Design

The proposal calls for the shielded pool to be deployed as a system contract using a UTXO-based design with no admin key, proxy, or pause mechanism. Spends are verified via a fork-managed Groth16 BN254 proof. The design allows sends to work with any existing Ethereum address or ENS name, requiring no separate privacy-specific address format.

Lehman's Rationale

Lehman argued that competition among privacy pools fragments anonymity sets, weakening privacy guarantees for participants. EIP-8182 would address this by giving every wallet and application on Ethereum a single shared pool to build on, eliminating the fragmentation problem that prevents new pools from achieving meaningful anonymity.

Related Proposals and Hegota Roadmap

Two additional proposals complement EIP-8182 in the privacy infrastructure stack. EIP-8141 allows privacy pools to pay withdrawal fees from the withdrawn funds. EIP-8250 adds keyed nonces to unblock shared-sender privacy designs. Developers formally added FOCIL, a censorship-resistance mechanism, as the upgrade's consensus-layer headliner in February. Vitalik Buterin called the FOCIL addition part of building a "cypherpunk principled" Ethereum.
