Buterin: ERC-3770 and ERC-7683 can greatly improve cross-chain user experience

In the early morning of today (20th), Vitalik Buterin, co-founder of Ethereum, said in response to the fragmentation problem in the multi-chain era that synchronous atomic composability has been overemphasized, and proposed his view on cross-chain Insights into chain interaction and user experience issues.

V God proposed a solution

Vitalik asks everyone to think about the cross-L2 operations we are already doing or want to do. Which of them can be made more seamless? For him, the two most important examples are:

• I have coins on Optimism and I want to pay Bob, but Bob is on Arbitrum.

• I have coins on Taiko and I want to use a dapp on Polygon, so I need to transfer the coins to Polygon in order to use that dapp.

Vitalik emphasized that these are not sophisticated technical issues that must be solved by solving synchronization issues, but user experience issues that can be improved by:

• Wide adoption of ERC-3770: so that addresses can contain chains information, making the address once again a "how to pay me" identifier.

• Cross-L2 exchange protocol (such as ERC-7683): ​​This allows cross-chain sending to be done programmatically, avoiding the need for users to deal with which intermediaries are trusted and which APIs to connect to.

• Wallet integration: When sending across L2, users only need to enter the payee's ERC-3770 address as usual.

Vitalik said that although solving technical problems can improve efficiency, such as making the cross-chain exchange market more friendly to liquidity providers, thereby shortening the withdrawal time from 1 week (optimistic rollups) to 1 hour (now zk rollups) Then to 1 slot (i.e. 12 seconds, ideal zk rollups). But Vitalik believes there are currently many untapped improvements that can be made without relying on synchronicity.

In conclusion, Vitalik’s response emphasized that the focus should be on improving the user experience rather than just solving technical problems. Through widespread adoption of new standards (such as ERC-3770 and ERC-7683) and improved wallet integration, users' practical problems in cross-chain operations can be more effectively solved, rather than overly relying on sophisticated technical solutions.

What is synchronized atomic composability?

Synchronous atomic composability means that in a blockchain ecosystem, different smart contracts and operations can be executed synchronously within the same block, and these operations are atomic, that is, either all succeed or All failed. This feature allows more complex cross-contract and cross-chain interactions to become possible and reliable, which is very important for increasingly complex DeFi applications and cross-chain applications.

However, as Vitalik mentioned, although synchronous atomic composability can technically solve many problems, it may not be the optimal solution in terms of actual user experience improvement. Simpler and more straightforward improvements, such as better standards and protocols, may lead to more significant user experience improvements.
