We are pleased to inform you that as of October 9, 2025, SISC v1.0 has been officially upgraded to the new version, SISC v2.0 (new contract address: 0xf7298b2D634FDFfbF758e84c194Ad1a9434eEbb0).
This version upgrade aims to enhance functionality and ensure the sustainable increase in value of the SISC.
■ About SISC v2.0
SISC v2.0 introduces a number of new features.
Among them, the most groundbreaking is the data compression and storage function onto the public blockchain.
This feature enables efficient compression and permanent storage of vast amounts of information collected from our semiconductor products onto the blockchain.
The accumulated data — such as temperature and humidity readings from home appliances and mining machines — will be analyzed by our proprietary AI and utilized in various services designed to help people live better lives.
■ Migration from SISC v1.0 to SISC v2.0
Please note that SISC v2.0 is a separate coin from SISC v1.0.
Accordingly, holders of SISC v1.0 will be eligible for a free exchange to SISC v2.0, in accordance with the procedure described below (“Exchange Eligibility and Method for SISC v2.0”).
The exchange rate is 1:1, so there will be no reduction in your asset value.
The version upgrade for the SIS mining pool and the exchanges BitMart and LBank, where SISC is listed, has already been completed.
You may now deposit, withdraw, and trade SISC v2.0 on these exchanges without issue.
