If Ethereum EIP-8182 is implemented, it will become the world's largest privacy chain, and it may also draw liquidity away from some other privacy coins (including users with privacy needs on BTC).
How to understand?
Currently, Ethereum is completely open and transparent; when you transfer an ETH, everyone can see the sender, receiver, and amount on the chain.
The existing privacy solutions (such as Tornado, Railgun, Aztec, etc.) are third-party dApps and have several pain points:
• Each project's "anonymity set" (size of the mixing pool) is very small, reducing privacy effectiveness;
• Different projects are incompatible with each other, dispersing users;
• They are easily targeted by regulators (Tornado Cash has been sanctioned by OFAC).
What is EIP-8182?
In March 2026, developer Tom Lehman proposed EIP-8182, Private ETH and ERC-20 Transfers. It is currently in draft stage.
It aims to directly embed a unified shared privacy pool (shared shielded pool) + zero-knowledge proof (ZK) precompiles in the Ethereum protocol layer (L1).
The main components are:
• A super large shared pool: all wallets and all dApps use the same pool, which would greatly enlarge the anonymity set (Ethereum is the largest public chain, with the most users and funds, and theoretically the strongest privacy effect).
• Native support: ETH and any ERC-20 can be privately transferred directly, as simple as a regular transfer.
• System contracts + split proof architecture: the pool is a system contract with a fixed address, without administrators, governance tokens, or upgrade privileges, can only be upgraded through hard forks (extremely decentralized).
• Zero-knowledge proof: The use of ZK technology proves "the money is coming from the pool, but it is not known which specific transaction," achieving complete privacy.
• No protocol fees: The pool itself does not charge any fees, and users only pay normal gas fees.
If EIP-8182 is implemented:
Then, it will make Ethereum the largest chain in terms of privacy, attracting liquidity from institutions and users, competing with privacy tokens like Zcash/Monero/Railgun for the privacy market share, and will also encourage some privacy-seeking users originally using BTC to shift.
• Ethereum has the largest ecosystem and the strongest liquidity;
• Once native privacy is realized, everyone can use it, and the anonymity set will far exceed existing privacy chains like Zcash, Monero, Railgun;
• It is equivalent to transforming "privacy" into a native feature of Ethereum, rather than an add-on, directly upgrading ETH from a "transparent public chain" to the "largest privacy public chain".
Finally, considering institutional compliance issues, if EIP-8182 passes, it can be combined with Zama to overlay FHE contracts on the privacy pool, achieving "strong privacy + regulatory compliance".
