Circle's USDC stablecoin has launched on the XRP Ledger (XRPL), enabling users to transfer stablecoins between decentralized exchanges using XRP as a bridge currency. USDC is the second-largest stablecoin with a market cap over $61 billion. This launch comes amid efforts to regulate stablecoins in the US, where the sector exceeds $237 billion in market capitalization. Stablecoins are seen as a link between traditional finance and crypto, with implications for US dollar hegemony and debt management. US Treasury supports stablecoin development to maintain dollar dominance, while critics argue stablecoins only delay the dollar's decline. Gold-backed stablecoins are considered strong competitors due to gold's value stability.
