Ethereum London Upgrade is scheduled to take place at Block 12,965,000. 

Users on Bitbns just need to hold ETH and ERC20 tokens in their wallets and we will take care of all technical work during the upgrade. Deposits and withdrawals of ETH and ERC20 tokens will be paused until further announcement.

What happens during a network upgrade?

After the community comes to an agreement concerning which changes should be included in the upgrade, changes to the protocol are written into the various Ethereum clients, such as geth, Erigon, Besu and Nethermind. The protocol changes are activated at a specific block number. Any nodes that have not been upgraded to the new ruleset will be abandoned on the old chain where the previous rules continue to exist.

Please read London Mainnet Announcement for more information.

Onwards and Upwards,
Team Bitbns
