Graphene hosts the Graphene blockchain, API and a crypto exchange for GOLD trade.
The price of one GOLD equals one ounce of physical gold on the LBMA. Applicants who want to trade GOLD for fiat need to undergo GoldMint's KYC procedure. If accepted, the applicant’s GOLD cryptoasset is transferred from his, or her, GoldMint wallet to a special GoldMint account and is converted to fiat. GoldMint sends this fiat to the applicant. So, the price with commissions you receive for buying GOLD is LBMA + 5%, selling - LBMA + 2%. Therefore the way fiat => GOLD => fiat will be 3%.
When physical gold is withdrawn from Custody Bot, the corresponding number of GOLD assets are destroyed.
