Open Wallet Standard AI Agents Hackathon Brings XRP Ledger & RLUSD

MoonPay’s Open Wallet Standard (OWS) is hosting a multi-city hackathon on April 3 to build AI agents for on-chain payments. RippleX confirmed it will join with XRPL and RLUSD challenge tracks, targeting “agentic finance” and x402-based settlement. Builders can register at hackathon.openwallet.sh. The OWS challenge categories include Agentic Payments, Agentic Commerce, Wallets, Identity, Guardrails, and Settlement Infrastructure. MoonPay says builders using x402, RLUSD, or the XRP Ledger are in scope. OWS is designed to let AI agents hold value, sign transactions, and pay across multiple blockchains without exposing private keys. The standard uses a single encrypted vault and a shared signing interface across EVM, Solana, Bitcoin, TON, Tron, Filecoin, and XRPL. The wallet model encrypts keys at rest (AES-256-GCM) and keeps the agent from directly seeing private keys. For settlement, the XRPL track highlights that OWS derives XRPL accounts from one seed phrase and uses a policy engine to enforce spending limits before keys are used. The article links x402 to broader infrastructure momentum after x402 moved to the Linux Foundation with backing from major tech and payment firms. RLUSD is positioned as the regulated stablecoin that fits into XRPL settlement flows for agent-to-agent payments without a human in the loop. A Dragonfly executive cautioned that agentic payments remain experimental, with x402 processing about $1M in daily volume. Even so, RippleX’s participation suggests continued momentum for bringing Open Wallet Standard wallet infrastructure into live agent-payment testing.
