https://eips.ethereum.org/EIPS/eip-5564 TLDR: Generate one-time recipient addresses This specification establishes a standardized method for interacting with stealth addresses, which allow senders of transactions or transfers to non-interactively generate private accounts exclusively accessible by their recipients. Moreover, this specification enables developers to create stealth address protocols based on the foundational implementation outlined in this ERC, utilizing a singleton contract deployed at `0x55649E01B5Df198D18D95b5cc5051630cfD45564` to emit the necessary information for recipients. In addition to the base implementation, this ERC also outlines the first implementation of a cryptographic scheme, specifically the SECP256k1 curve.
