- BNB Chain’s Jenner hard fork is set to take place on October 28, 2026, on the BNB Smart Chain testnet.
- Payment Lane will automatically set aside 5% of the block gas capacity for payments. This limit can be adjusted,. The maximum will not go beyond 10% unless governance decides otherwise.
- CAS20 will bring controls for stablecoins and tokenized real-world assets. These controls are not active by default. Will require separate activation.
BNB Chain will launch the Jenner fork on the BNB Smart Chain testnet on October 28, 2026. BNB Chain will give block space for payments that are eligible. BNB Chain will also improve contract timing and add new controls for digital assets.
BNB Chain will need validators, node operators, block builders, and application developers to set up their infrastructure and test compatibility before the upgrade goes live.
Jenner hardfork is coming to BNB Smart Chain testnet on Oct 28.
Validators, node operators, block builders, and application developers: start preparing for the upgrade.
Jenner includes:
🔸 Payment Lane, reserving 5% of block gas by default for eligible payments.
🔸 Millisecond block timestamps for smart contracts.
🔸 Functionality for CAS20, a new Compliant Asset Standard. More details on its availability will follow separately.Testnet node operators must upgrade to a compatible client before activation. Developers should review the changes affecting their applications and tooling.

On October 22, BNB Chain Developers posted on X. Asked all network participants to read the upgrade requirements and install the right software before the launch. BNB Chain has not yet announced the mainnet activation date.
BNB Chain Jenner Upgrade Introduces Payment Lane
One of the changes is called Payment Lane. This will set aside 5% of each block’s gas capacity by default for payment transactions that meet conditions.
The amount that is set aside could go up to a maximum of 10% through network governance. Eligible transactions are BNB transfers to accounts that do not have a contract code and payments sent to approved payment contracts.
The feature is meant to give payments a dedicated block capacity when the network is busy. It does not promise immediate processing. Also, regular transactions cannot use the reserved capacity even if it is not being used.
CAS20 Standard Brings New Digital Asset Controls
The Jenner hard fork will also bring the core features needed for CAS20, a ruleset made for assets like stablecoins and tokenized real‑world assets (RWAs).
The proposed controls for CAS20 consist of approved address lists, blocked address lists, an option to pause activity, and independent permissions for minting, burning, and seizing tokens.
These abilities could help projects that need control over the transfer and management of assets. However, the hard fork does not automatically turn on all CAS20 functions. A person chosen by governance must turn on each required function separately.
BNB Chain has said it will give information about when CAS20 will be ready and how it will be integrated in an upcoming announcement.
Millisecond Timestamps Expand Smart Contract Timing
Another major change arrives with BEP-706, which brings a tool located at address 0x70. This tool lets smart contracts get block timestamps in milliseconds of seconds.
The extra accuracy might help applications handle time tasks, such as auctions, time-limited quotes, and checking if price feeds are up to date. Contracts that use block.timestamp will still get timestamps in seconds. Programmers need to use the tool on purpose to get millisecond precision.
The update also adds checks for blocks that are being proposed and allows sending blocks through gRPC. People who run nodes with the Reth client should look at the release notes before updating.
