Update: Ethereum’s Istanbul Hard Fork

The block height for Ethereum’s Istanbul hard fork is 9069000.BitGo will disable all Ethereum services 30 minutes prior to the fork and restore the services 30 minutes after the fork.All deposits made to wallets while the services are disabled will be reflected on the wallet balance once the services are restored.

We highly recommend that clients do not send transactions or generate wallets and addresses during the downtime.If an API call is run during the downtime the calls will be queued and processed once the services are restored. Some API calls may return an error. The type of the error will vary based on the API call.

All BitGo services will remain operational during the BCH fork while BitGo disables Ethereum services for 30 minutes prior to and after the Ethereum fork. Any changes to the schedule or approaches outlined below will be reflected on this blog post via an update.
