[Vitalik: Base, as an Ethereum L2, possesses non-custodial characteristics, with fund security ultimately guaranteed by L1] Odaily Planet Daily News – Vitalik Buterin posted on the X platform stating that Base, as an L2 built on Ethereum, enhances user experience through centralized features while relying on Ethereum's decentralized foundation for security. Base does not have fund custody permissions, cannot steal user assets, or block withdrawals, aligning with L2beat's definition of Stage 1. He pointed out that if an L2 ceases operations, users can still retrieve funds automatically through Ethereum contract logic. Additionally, there are existing cases demonstrating that L2s can prevent operators from censoring transactions. Vitalik emphasized that L2s are extensions of Ethereum rather than custodial servers, with user funds ultimately controlled by Ethereum L1, making them immune to theft or freezing by L2 operators.
