Jesse Pollak Highlights Base Testnet Vibenet With 200ms Blocks and Native AA

Base lead jessepollak spotlighted new features on base shipping on Vibenet, a test network for the Ethereum Layer-2, in a post on Sep. 2, 2026. The announcement builds on a detailed rundown from dmericliu, who invited builders to experiment with three capabilities live on Vibenet before they reach Base.

Vibenet offers 200ms blocks — sub-second confirmation natively, without requiring a separate Flashblocks layer. Apps can benefit from instant-feeling transactions with zero contract changes. Also live are validity transactions, which let users attach conditions (like a price or block index) to a transaction so it executes only when that condition is met, reducing wasted probe transactions and improving fills for searchers and market makers. The third feature is EIP-8130 native account abstraction, bringing gas sponsorship, session keys, and batched calls directly into the protocol, enabling smart-account UX without deploying smart contract wallets.

Base is Coinbase's Ethereum Layer-2 network built on the OP Stack, led by jessepollak, and has no native token. Vibenet serves as a public playground for testing what's next on Base before mainnet deployment. Pollak's endorsement signals these features are likely candidates for upcoming Base upgrades, though no timeline for a mainnet rollout was provided.

Developers can try Vibenet via the link in dmericliu's post, with feedback encouraged as Base continues to iterate on its roadmap.
