Binance Smart Chain Upgrade: BEP20 Maintenance

The Binance Smart Chain (BSC) network upgrade and hard fork will take place at Binance Smart Chain (BSC) block height of 13,082,000, or at approximately 2021-11-30 08:00 (UTC). Deposits and withdrawals on the Binance Smart Chain (BSC) network will be suspended starting from approximately 2021-11-30 07:45 (UTC).

In order to ensure the safety of customers’ assets, ONUS will simultaneously maintain BEP20 On-chain transactions during this upgrade.

Accordingly, from 07:45 UTC November 30, users will not be able to make On-chain deposits/withdrawals for BNB and other tokens through the Binance Smart Chain (BEP20) network. ONUS will announce users as soon as the maintenance is completed.


  • Other features applicable to BNB tokens such as Daily Staking, Off-chain Transactions, Exchange,… still open normally.
  • To avoid unexpected occurrences, we recommend that you complete deposits and withdrawals for BNB and other transactions on the BEP20 network before the upgrade and hard fork period.
