Ripple bets on AI agents as USDC dominates machine payments

Ripple has unveiled a developer toolkit enabling AI agents to execute automated payments via the XRP Ledger, a direct attempt to challenge the dominance of USDC in the burgeoning x402 machine-payment sector where stablecoins currently account for the vast majority of transaction activity.

The newly released XRPL AI Starter Kit allows autonomous software agents to manage payments on the XRP Ledger with minimal human oversight. By integrating XRP and Ripple USD (RLUSD) into the x402 protocol—a system that utilizes HTTP 402 “Payment Required” codes—Ripple aims to streamline how AI agents settle invoices or purchase computing resources. The toolkit provides essential infrastructure for platforms like Claude Code, Cursor, and custom agent frameworks to perform balance checks and transaction tracking directly within web requests.

Despite this push, Ripple faces a steep climb against the established market leader. Data from Web3 Trackers indicates that USDC has powered over 120 million cumulative x402 transactions, totaling more than $41 million in settled volume. While Base and Solana currently serve as the primary hubs for this activity, Ripple is banking on the XRP Ledger’s three-to-five-second settlement times and native multisignature support to win over developers.

Beyond AI, the company is aggressively expanding its payment reach. Through recent partnerships, Ripple has integrated its RLUSD stablecoin into Mastercard’s settlement network and incorporated Bitso’s MXNB token to bolster cross-border liquidity between the U.S. and Mexico. However, the company has yet to announce specific production-scale deployments or transaction volumes for its AI agent tools. Meanwhile, researchers warn that the x402 protocol itself introduces complex security hurdles, specifically regarding payment authorization and the synchronization of web services with blockchain-based verification.
