Odaily Planet Daily News Vitalik Buterin demonstrated the current interface for depositing to Polymarket and the comparison of the interface that should be presented at X, and called on the industry to work together to launch ERC-3770 and ERC-7683. Earlier news, Vitalik Buterin said in response to netizens' discussion 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 sending can be done by entering the recipient's address in the same text box. “Sending a 100% ETH to an ERC-3770 address is now possible, just like you do a regular send today. Solving the technical issues could indeed make this process more efficient, particularly by making cross-chain swap markets friendlier to liquidity providers, 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 then, there are multiple orders of magnitude of untapped benefits that don’t even require synchronicity to be involved.”
