Vibenet is Base’s experimental preview network where new chain-level features are available before they roll out to Sepolia or Mainnet. It currently hosts B20 tokens — an ERC-20 superset with built-in roles, supply caps, pausing, policy gating, and permit implemented as a native precompile.Use Vibenet to build against cutting-edge Base features. It is not intended for production or user-facing applications. Learn more at vibes.base.org.
