04/01: Notice Regarding Future Transition of SBI Crypto Mining Pool Operations

Thank you for your continued support.

As previously communicated, SBI Crypto has been reviewing its overall operating structure and the future direction of its mining pool business, including the suspension of operations on weekends and Japanese public holidays, as well as the discontinuation of LTC / DOGE-related operations.

Following this review, SBI Crypto is moving forward with a planned transition of its mining pool business, with the current expectation that the existing operating structure will be wound down by the end of July 2026.

At this time, this does not mean an immediate suspension of services. Our current focus is to support an orderly transition while continuing necessary operations and customer support during this period.

We are also reviewing the most appropriate transition arrangements for the business, operations, and related infrastructure, and we will communicate further updates as necessary.

During this period, customers may continue to use the service as usual unless otherwise notified. Further details regarding future operations, API / service availability, customer-related arrangements, and other operational matters will be communicated separately as appropriate.

Customers are encouraged to ensure that any data required for accounting, audit, tax, or other internal purposes is extracted in a timely manner prior to any final service conclusion. Any outstanding payment or settlement-related matters should also be raised with us in due course.

We sincerely appreciate your understanding and cooperation as we work to ensure an orderly and responsible transition.

If you have any questions regarding this notice, please feel free to contact us directly.
