According to ChainCatcher, Vitalik Buterin posted a message on social media today urging industry participants to start launching ERC-3770 and ERC-7683, pointing out issues that may affect the potential future expansion of address space for community users.

He added that the main challenge of 32 bytes is at the contract level (many contracts use mod 2** 160 to handle addresses), while ERC-3770 is at the UI level, and the two are orthogonal to each other.
