Ethereum Network Hard Fork Notice

Developers of the Ethereum blockchain (ETH) have released a new software version called “Istanbul” to activate hard fork rules as confirmed by the Ethereum Foundation team lead, Péter Szilágy. The hard fork will activate at block height #9069000, which is estimated to occur on 7th December 2019 at around 22:15:00 (UTC). The exact time will vary as the activation is associated with the block number.

You can follow the countdown timer or your own updated Ethereum node for a more precise estimate (we cannot be held responsible for inaccuracies with third party countdown timers).

BTSE will follow the “Istanbul” hard fork. The hard fork is not expected to be controversial, although if two chains do result, BTSE will only consider the Istanbul rules to be Ethereum (ETH). Our policy is to not support the so-called “fork coins” by default, so if you believe two chains may result from this hard fork and wish to claim any resulting tokens, please withdraw your coins to your own wallet (where you control the private keys) before the hard fork occurs.

To protect our users against network instability during the hard fork transition, BTSE will stop processing deposits and withdrawals of Ethereum (ETH) and Ethereum contract-based tokens (ERC20, etc), at approximately 15:30 (UTC) on 7th December 2019, from block #9067560.

Deposits and withdrawals will be resumed once we are confident that the hard fork rules have successfully taken effect across the ecosystem. We would expect this period to last less than 24 hours under normal circumstances.

Our aim is to create a platform that offers you the most enjoyable trading experience. If you have questions or suggestions, please don’t hesitate to reach out to us at or DM us on Twitter: @BTSEcom.
