XRP

Ripple joined the x402 Foundation as a Premier Member, placing XRP and its RLUSD stablecoin inside an open payment standard for AI agents alongside 40 major institutions. XRP Ledger has cleared more than one million agentic transactions, but still trails Coinbase’s Base network by a wide margin.

Ripple became a Premier Member of the x402 Foundation on July 14, the same day the body launched under the Linux Foundation to govern an open standard for machine-native payments. The move places both XRP and RLUSD, Ripple’s dollar-backed stablecoin with a $1.26 billion market cap, inside a payment framework that 40 institutions across finance, cloud, and blockchain are now building on.

The x402 protocol revives the HTTP 402 Payment Required status code, turning it into a machine-readable payment flow. When an AI agent requests a paid service, the server returns a required amount, an accepted asset, and a receiving address; the agent’s wallet then signs and sends the payment, and the content or compute is delivered after settlement. No human approves the transaction, and no bank account is involved.

What Ripple built before joining

The membership caps months of infrastructure work rather than a standalone announcement. In June, Ripple released the XRPL AI Starter Kit, a toolkit with an MCP documentation server, an agent wallet skill, and a tutorial guiding developers to a confirmed XRPL transaction supporting x402 payments in XRP and RLUSD. Ripple-backed t54.ai then launched the XRPL AI Hub for developers building AI applications on the ledger.

The technical profile fits the use case. XRPL transactions reach deterministic finality in three to five seconds, with fees fixed at approximately $0.0002. Agents can run non-custodial wallets funded with XRP or RLUSD and retain XRP earned from completed tasks to fund future work.

Where XRPL sits in the x402 race

The competitive gap is wide. Coinbase’s Base network has processed more than 119 million x402 payments, and Solana has handled roughly 35 million, both settling most volume in USDC. By comparison, the XRPL Foundation confirmed the network surpassed one million agentic transactions shortly after x402 support launched.

The foundation is network-neutral, so XRP competes with USDC, cards, and other chains under the same standard. Membership gives Ripple a governance role in how that standard evolves, which the source argues matters more at this stage than raw transaction counts.
