A stablecoin is a token designed to hold a steady value, usually one US dollar. The most common kind is backed by reserves: for every token in circulation the issuer holds a dollar or a short-term government bill, and redeems tokens for dollars on request.
USDG, the dollar token Gleo's payment tools use on Robinhood Chain, has six decimals. Its total supply is read live on Gleo's network panel straight from the contract.
Questions worth asking
Who holds the reserve, and who audits it? Can the issuer freeze an address? How quickly are redemptions paid? The answers decide whether a stablecoin is suitable for payroll, remittances or a lending market.
