What is a pay alias?

Direct answer

A pay alias is a human-readable name like pay:yourname that resolves to your payment details, so a person or AI agent pays you without touching your account number. On DNS://Money it resolves to XRPL or RLUSD today, and agents pay it over x402 on five networks.

How is it different from a bank alias?

You may know aliases from FedNow, RTP, Pix, or Visa+, where a phone number or email maps to a bank account. A pay: alias is broader on two axes:

 pay: alias (DNS://Money)Bank alias (FedNow/RTP/Pix/Visa+)
Resolves tofull payment instructionone bank account
RailsXRPL, RLUSD; x402 on Base, Solana, Algorand, X Layersingle rail
Built for AI agentsYesNo
Identifiera chosen name (pay:agent.compute), with an optional X handle as public metadataphone / email

How does it work?

  1. Claim a name once: pay:yourname.
  2. A sender resolves it. The protocol returns the rail, address, and routing to pay.
  3. Fixed rules pick the rail from the alias's endpoints and the asset requested.
  4. It settles on that rail from the sender's own wallet, and DNS://Money records it. You can repoint the alias at any time; the name never changes.

Can AI agents use it?

Yes. On 2026-03-13, two AI systems resolved pay: aliases and paid each other on XRPL mainnet, autonomously and on-chain. View the genesis transaction →
