ChainCatcher news, Vitalik Buterin posted on social media today urging industry participants to start working on ERC-3770 and ERC-7683, addressing potential issues that may affect future address space expansion for community users.He added that the main challenge of 32 bytes lies 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.

ChainCatcher news, Vitalik Buterin showcased the current interface for depositing into Polymarket on X and compared it with the interface it should present, calling for the industry to work together to launch ERC-3770 and ERC-7683.

ChainCatcher message, Ethereum co-founder Vitalik Buterin stated on social media that, in my opinion, synchronous atomic composability is overrated.For example, think about some specific cross-L2 things you are doing or envisioning that could be more seamless.For me, the two most important things are:I have coins on Optimism, and I want to pay Bob, but Bob is only on Arbitrum.I have coins on Taiko, and I want to use a dapp on Polygon, so I need to send to Polygon to use that dapp.These are not fancy problems that can be solved just by addressing the synchronization issue. These user experience issues can be resolved in the following ways:(i) Widely adopt ERC-3770, making the chain part of the address, thus making the address once again a self-contained "how you pay me" identifier;(ii) Cross-L2 exchange protocols (like ERC-7683), allowing for programmatic cross-chain sending without getting tangled up in which specific intermediaries to trust and which APIs to connect;(iii) Wallet integration, so that you can simply put the recipient's ERC-3770 address into a text box to complete the cross-chain sending, just like you do for a regular send now.
