Private transactions in Ethereum: EIP-8182 standard proposed for Hegota update

🔐 Basic privacy: Ethereum proposes a unified pool for private transactions

Co-founder of the protocol Facet Tom Lehman initiated the integration of the standard EIP-8182 into the upcoming Ethereum update codenamed Hegota. The proposal involves creating a secure pool for private transfers of ether and ERC-20 standard tokens at the base protocol level.

This is not just a technical improvement, it's an attempt to solve the fundamental problem of privacy in public blockchains: fragmentation of liquidity and complexity of user experience.

⚙️ How the system will work?

The architecture of EIP-8182 is based on several key principles:

🔹 Unified privacy pool: instead of disparate mixers - a common environment accessible to all wallets and dApps, enhancing anonymity through network effect;
🔹 Zero-knowledge proofs: a cryptographic protocol Groth16, is used to validate transactions, hiding the sender, recipient, and amount;
🔹 No admin keys: the smart contract is deployed without pause or intervention capabilities, eliminating protocol-level censorship;
🔹 Ease of use for the user: sending hidden transfers to regular addresses or ENS domains without creating separate accounts.

Current mixing services work poorly due to fragmentation. New pools find it difficult to attract users without a ready-made base, and without liquidity, they do not provide the necessary anonymity, Lehman explains.

📦 Additional standards: solving the problem of commissions

In addition to EIP-8182, two more proposals are planned to be included in the Hegota update:

✅ EIP-8141 and EIP-8250: solve the problem of paying gas fees when withdrawing funds from a private pool, allowing fees to be paid in tokens or through meta-transactions.

This eliminates one of the main barriers to private transfers: the need to keep a separate ETH balance for gas.

🗓 Context of the Hegota update

The upgrade is scheduled for the second half of 2026 and includes several strategic components:

🔹 FOCIL mechanism: a tool to combat censorship at the level of including transactions in blocks;
🔹 Privacy priority: Vitalik Buterin has repeatedly called confidentiality the basis of freedom in the digital age;
🔹 Institutional support: in October 2025, the Ethereum Foundation formed a team of 47 specialists, focused on enhancing the confidentiality of the base layer;
🔹 Tools for developers: in November, Buterin introduced Kohaku an open-source modular stack for creating private wallets.

⚖️ Balance of privacy and regulation

The initiative sparks discussion in the community:

✅ Pros: a unified standard simplifies development, enhances anonymity, and lowers the entry threshold for users;
⚠️ Risks: private transactions may attract regulatory attention, especially in the context of AML/CFT requirements.
