The Ethereum Foundation has proposed a hard fork in response to the DAO exploit. The decision to create this hard fork has been supported by the majority of the Ethereum community. The hard fork will occur at block 1,920,000. This will be on Wednesday, July 20th (Australian Eastern Standard Time).
As a BTC Markets customer, your full Ethereum balance will be automatically migrated to the winning chain and you do not have to do anything.
Be advised that during the migration on Wednesday July 20th, deposits and withdrawals will be temporarily suspended. If you do not want your Ethereum balance to be automatically migrated to the winning chain, we advise withdrawing your funds prior to this date. Trading will continue as per usual.
Once the winning chain is up and running, deposits and withdrawals will resume as normal. The losing chain will be decommissioned and will not be supported by BTC Markets.
