The Institutional Stablecoin Stack Just Completed in 72 Hours — Five Layers Shipping Simultaneously
Between October 6-8, 2026, five infrastructure layers for institutional stablecoins were completed, forming a stack to comply with the GENIUS Act. The reserve layer includes JPMorgan's JLTXX ($733.7M AUM) and BlackRock's BSTBL ($6.1B parent fund), with a 40% concentration limit. SAP integrated USDC and EURC into its ERP software, while Moody's and S&P provided stablecoin protocol ratings.
