Ripple on Wednesday introduced the XRPL AI Starter Kit to support developers in building autonomous payment systems and AI agents on the XRP Ledger.
The deployment was built in collaboration with t54 Labs, a startup that closed a $5M seed funding round in late February 2026 with Ripple as a strategic investor. Other backers included Anagram, PL Capital, and Franklin Templeton, one of the largest asset managers in traditional finance.
What the x402 standard actually does
The x402 standard works by piggybacking on HTTP 402 responses. When an AI agent hits a paywall or needs to complete a transaction, the server returns a specific HTTP status code that tells the agent exactly how to pay. The agent processes the payment in XRP or RLUSD and gets access. No login forms, no credit card fields, no OAuth tokens.
Coinbase and BNB Chain have also implemented x402 for machine-native transactions. XRPL’s implementation supports both a volatile asset (XRP) and a stablecoin (RLUSD) natively, giving AI agents the option to pay in a stable unit of account or settle in XRP.
