GoldZIP Token (XGZ) is the first gold backed digital token issued by the subsidiary of Chinese Gold & Silver Exchange (CGSE). The Exchange was established in 1910 and it is the sole precious metal exchange in Hong Kong.

The amount of gold representing the supply for GoldZIP is a 1:1 ratio - one gram of gold equals to one XGZ token. The total supply of XGZ is minted from selected brands of gold bars and equates to the total supply within the vault.

Currently ABT exchange supports buying XGZ tokens with USDT from an ERC-20 address. When you want to sell XGZ, we will accept XGZ from a VSYS address.

Whenever you buy or sell XGZ Token from ABT exchange pages, ABT-Dex will charge a small fee to process the transaction. There are two types of transaction fees that are associated with transferring XGZ token from one VSYS address to another.

  • Standard ‘gas’ fee: When sending digital assets on Ethereum, a computing power called ‘gas’ is required. Like any other token on the Ethereum blockchain, USDT will require a standard gas fee paid in ETH to compute the transaction. For V SYSTEMS blockchain, XGZ will require 0.3 VSYS gas fees paid to compute transactions on the VSYS blockchain.

  • ABT ‘on-chain transaction' fees: ABT will charge an additional fee that is set as 0.3% of the amount of USDT sent on the blockchain.

Yes! GoldZIP (XGZ) tokens are fungible tokens which are divisible to up to 6 decimal points. If you purchase XGZ tokens from ABT-DEX, there is a minimum purchase amount of 0.01 XGZ.
