Vitalik: Synchronous atomic composability is overestimated, L2 cross-chain can be solved by solutions such as ERC-3770

Vitalik: Synchronous atomic composability is overestimated, L2 cross-chain can be solved by solutions such as ERC-3770

Odaily News Ethereum co-founder Vitalik Buterin said in response to netizens related discussions on X: Synchronous atomic composability is overestimated. For example, think about some specific cross-L2 things you are already doing or imagine doing, which could have been more seamless. For me, the two main problems are: 1. I have coins on Optimism and I want to pay Bob, but Bob is only on Arbitrum; 2. I have coins on Taiko and I want to use a DApp on Polygon, so I need to send the coins to Polygon to use them. These are not advanced technical problems that can be solved by solving synchronization, but user experience problems that can be solved by the following methods: 1. Widespread adoption of ERC-3770, making the chain part of the address, so that the address once again becomes a self-contained how to pay me identifier; 2. A cross-L2 exchange protocol (such as ERC-7683), so that you can perform programmatic cross-chain sending without worrying about which specific intermediaries to trust and which APIs to connect to; 3. Wallet integration, so that cross-L2 Sends can be done by entering the recipient’s ERC-3770 address into the same text box, just as you do a regular send today. Solving the technical issues can indeed make this process more efficient, particularly by making cross-chain swap markets friendlier to liquidity providers and reducing withdrawal times from 1 week (optimistic rollups) to 1 hour (current zk rollups) to 1 slot (ideal zk rollups with proof-of-stake aggregation). But even so, there are multiple orders of magnitude of untapped benefits that don’t even require synchronicity to be involved.”
