Data from XRPL AI Hub indicates that autonomous AI agents using the XRP Ledger for settlements are increasingly opting for regulated stablecoins like Ripple USD (RLUSD) over native crypto assets such as XRP. This trend is driven by the machines' need for predictable costs, as XRP's price volatility can undermine their financial models. BlackRock's research note, "The Machine-Native Economy," highlights this shift, predicting that the traditional banking system cannot handle the millisecond micropayments required by autonomous software. BlackRock estimates the global stablecoin market has already surpassed $300 billion, with an annual transaction volume of $11.6 trillion, making stablecoins a fundamental unit of account for AI-driven transactions.
