Shanglian Sanbao’s Jinruibao GBT is a certificate created and issued by physical gold depository. Through the depository consensus, it is ensured that each GBT created and issued on the chain has a sufficient amount of physical gold for acceptance. Anyone who owns physical gold can create a corresponding amount of GBT by entrusting physical gold through a designated agency with gold operating qualifications in accordance with the depository consensus process. Anyone who owns GBT can exchange it for a sufficient amount of physical gold after paying the handling fee through designated outlets. The total amount of creation and issuance of GBT depends only on the total amount of physical gold deposited.
