Over just 18 months, tokenized US Treasuries and money-market funds have grown from about $2 billion to roughly $9 billion across 60 products and 57,000 addresses, offering average seven-day yields near 3.8%. As part of a broader $19 billion real-world asset (RWA) stack on public blockchains, these tokenized T-bills now function as the de facto base collateral layer—similar to their role in the $5 trillion U.S. repo market.
