Yellow Network, a venture backed by Ripple co-founder Chris Larsen, has deployed an "ultimate" AI settlement stack. This technology utilizes the XRP Ledger (XRPL) to enable instant, trustless machine-to-machine commerce, with the XRP token serving as the basic settlement mechanism. The infrastructure is already active on the XRPL AI Hub, where 174 AI services have registered, completing over 14.5 million microtransactions and nearly 6,000 deals.
