BNB Chain Testnet Enables the Jenner Upgrade
Start here
AI-assisted source synthesis · not an independent investigation.
On October 29, 2026, BNB Chain activated the Jenner hard fork on BSC Testnet, introducing the Payment Lane mechanism: each block reserves 5% of its gas capacity by default for processing eligible payments, and the governing body may increase this proportion to a maximum of 10%. Currently, transfers between BNB wallets are automatically included within the scope of payments; stablecoin transfers still require governance approval and inclusion on the approved list. The upgrade also adds a millisecond-level block time reading tool and includes the not-yet-enabled CAS20 standard. The mainnet upgrade date has not yet been announced.
