At the Consensus HK event, William Campbell highlighted a unique feature of the USDKG stablecoin, which differentiates it from typical stablecoins.

This approach aims to provide a different level of stability and security for the stablecoin, as discussed during the CoinDesk Live session in partnership with Hex Trust.
