Vitalik: Synchronous atomic composability is overrated
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.
