Agent payments on the XRP Ledger surpassed 4 million transactions, reaching 4,023,081 as of September 5, 2026, according to a public settlement dashboard. A separate update described the activity as nearly 4 million payments and reported 29% growth over four days. The network has recorded 5,753.43 XRP and 3,789.44 RLUSD in cumulative settled payments, with 148 registered merchants. Activity tracked by t54 rose from roughly 3.1 million on September 1 to 3,992,146 before the latest dashboard reading, underscoring adoption of x402, an HTTP-native protocol that enables AI agents to purchase APIs, compute, data and other digital services using XRP or RLUSD. RLUSD's market capitalization reached about $2.40 billion on September 4, up from roughly $2.07 billion on August 25. t54's selection for Mastercard's Start Path Agentic Commerce & Services program and support for Mastercard's Verifiable Intent framework connect the project to broader efforts to control authorization and risk in autonomous commerce, but do not represent Mastercard adoption of XRP as a settlement asset. XRP was trading near $1.40 and down about 4% over 24 hours in the cited data, creating a contrast between token performance and rising agent-payment activity. Ripple launched the XRPL AI Starter Kit in June 2026, while the broader ecosystem has added interoperability and lending initiatives through Axelar and VS1 Finance.
