Wu learned that Base has launched three building blocks, including Flashblocks, Base Appchains, and Smart Wallet Sub Accounts, aimed at improving the efficiency and experience of on chain applications. Flashblocks technology accelerates block confirmation speed by shortening the effective block time. It is currently available online on the Base Sepolia testnet and is expected to be launched on the mainnet in the second quarter of 2025. Base Appchains are L3 chains based on Base, supported by the op enclave framework, and help applications expand through dedicated block spaces. Smart Wallet Sub Accounts simplifies the user experience, reduces wallet pop ups, improves security, and eliminates the need for manual management of different on chain accounts. This feature has been launched on the Base test network and is planned to be launched on the main network in the second quarter of 2025. https://www.
