The Ethereum Foundation has proposed a hard fork in response to the recent denial of service (DoS) attacks. The hard fork will occur at block 24,63,000 on or around Tuesday, October 18th.
As an ETHEXIndia customer, you do not need to do anything. The migration will occur automatically, and your full balance of Ethereum will be transferred to the new chain. Keep in mind that as we near the fork, we will be temporarily disabling deposits and withdrawals in preparation for the migration process. Trading will continue to operate as normal during this period. Once the network is stable and the migration is complete, we will enable deposits and withdrawals.
If for any reason you would like to keep your tokens from the old blockchain, you must remove your ETH from the platform before the fork occurs.
