You can use USDC (US Dollar Coin) to buy tradable game items like Silver and Gold cards or to participate in the Conquest game mode. USDC is a stablecoin that is pegged to the US Dollar. This means the value of 1 USDC equals one real US Dollar.
USDC is generally regarded as a safer stablecoin because it is regulated by the government’s Financial Crimes Enforcement Network (FinCEN), which combats money laundering. It is also audited by one of the top 10 accounting firms in the world, Grant Thorton.
