ERC-5564 (Stealth Addresses)
An Ethereum standard for stealth-address payments — lets a recipient publish a single meta-address that resolves to a fresh on-chain address per incoming payment.
ERC-5564 standardizes how Ethereum stealth addresses are generated and announced on-chain. The recipient publishes a meta- address (encoding a spending public key and a viewing public key); the sender combines those with a random scalar to derive a fresh one-time address; the recipient scans incoming transactions with their viewing key to find theirs.
The standard, complemented by ERC-5564's companion ERC-6538 for the on-chain announcement contract, brings Monero-style address privacy to Ethereum as an opt-in primitive. UmbraCash and Fluidkey were among the earliest production implementations.
