最新报道:Ethereum co-founder Vitalik Buterin has proposed a new transaction type called "ERC-7621" that would allow batch transactions from multiple senders to a single receiver, potentially reducing gas fees by up to 90% for certain DeFi operations. The proposal, which builds upon existing ERC-4337 account abstraction standards, could significantly improve efficiency for applications like decentralized exchanges where users often need to make multiple token approvals. Buterin suggests this could be implemented as part of Ethereum's upcoming "Prague" hard fork, though developers note the concept is still in early discussion stages and would require careful security analysis before deployment.
