The Gold Appreciation Token (SAR-ASI), issued by the SAR Digital Asset Exchange on behalf of the SAR Precious Metals Exchange, is a digital asset token based on blockchain technology. Primarily applied in the circulation of digital assets and traditional payment sectors, it also serves as a dividend rights certificate corresponding to the income of physical projects at predetermined times. The SAR-ASI is secured by a total of 50 billion Euros worth of gold stored at UBS in Switzerland, with the real-time gold price from the Shanghai Precious Metals Exchange in China serving as a pricing benchmark. It boasts stable value, system security, convenient trading, and extensive circulation.
