BNB Chain rolls out Jenner hard fork on BSC testnet with dedicated payment lane

BNB Chain has activated the Jenner hard fork on the BSC testnet. The upgrade introduces three main changes: a reserved gas lane for payments, millisecond block timestamps, and the foundation for the new CAS20 token standard.

Under BEP-703 the Payment Lane sets aside 5 % of each block’s gas for simple BNB transfers. During high traffic the reserved space stays available only for qualifying payments, and governance can raise the limit to 10 %. Stablecoins are not yet included.

Smart contracts can now read block timestamps down to the millisecond via BEP-706. This helps time-sensitive apps set sub-second expirations without relying on whole-second clocks. Developers must enable the feature themselves.

CAS20 (BEP-702) lets issuers add compliance tools such as allowlists, blacklists and transfer pauses. The standard is not live yet and needs separate governance approval. No mainnet date has been announced.
