BNB Chain Jenner hardfork debuts Payment Lane, CAS20

BNB Chain’s Jenner hardfork is live on BSC testnet, adding Payment Lane, millisecond timestamps, and CAS20 asset standard. Full activation depends on governance approval.

BNB Chain has launched the Jenner hardfork upgrade on its BNB Smart Chain (BSC) testnet, introducing several notable features. The main highlight is the Payment Lane mechanism, which reserves 5% of each block’s gas capacity for eligible payment transactions, such as simple BNB transfers and approved payment contracts. This ensures payments are processed even during network congestion. The reserved allocation can be increased up to 10% through governance, though eligible payments still compete under existing fee rules. The upgrade also introduces millisecond-precision block timestamps for smart contracts, enhancing accuracy for time-sensitive applications. Additionally, it brings CAS20, a new compliance asset standard designed to support stablecoins and tokenized real-world assets on BSC. While Payment Lane and CAS20 require further governance approval before full activation, the Jenner hardfork is live on the testnet. The mainnet rollout date has yet to be announced. These upgrades aim to improve payment reliability, support compliant digital assets, and enhance DeFi and RWA capabilities on the network.
