[Vitalik Buterin: Synchronous atomic composability is overestimated] Ethereum co-founder Vitalik Buterin recently said on social media that synchronous atomic composability is over-exaggerated. He took cross-L2 operations as an example and pointed out that these problems cannot be solved by solving synchronization problems. He believes that the solutions include: widespread adoption of ERC-3770 to make the chain part of the address; implementation of cross-L2 exchange protocols such as ERC-7683 to programmatically send cross-chain; wallet integration, just enter the recipient's ERC-3770 address to complete cross-chain sending. He emphasized that solving these problems will greatly improve efficiency, especially by making the cross-chain exchange market more friendly to liquidity providers, significantly shortening withdrawal time.
