Global Dollar.

Global Dollar (USDG) was an ERC-20 token built on the Ethereum blockchain, designed to function as a stablecoin with its value pegged to the U.S. Dollar. It was issued and managed by Prime Trust, a Nevada-chartered trust company that offered various financial infrastructure services to the digital asset industry, including custody, funds processing, and tokenization. The underlying technology leveraged the established security and decentralization of Ethereum, making USDG compatible with a wide range of wallets, exchanges, and decentralized applications. The primary utility of USDG was to provide a stable medium of exchange within the cryptocurrency ecosystem, facilitating fast and efficient digital dollar transfers, remittances, and acting as collateral or liquidity in DeFi protocols. Its intended market significance stemmed from Prime Trust's regulated status and its role as a trusted custodian, which theoretically provided a higher degree of assurance regarding the backing of the stablecoin compared to some unregulated alternatives. However, the asset's viability was entirely dependent on the solvency and operational integrity of its issuer. Following Prime Trust's insolvency and subsequent receivership in 2023, the Global Dollar (USDG) stablecoin effectively became defunct. The collapse of its issuer rendered its 1:1 peg unsustainable and its redemption mechanism non-functional, leading to a significant loss of value and liquidity for token holders. Its market presence and utility have since evaporated, underscoring the critical importance of issuer health and regulatory oversight for centralized stablecoins.
