RLUSD Payment Rails for MCP Servers
RLUSD, Ripple's USD-pegged stablecoin, settles on the XRP Ledger as an IOU with the same ~3 second finality as native XRP. mcp-x402-xrpl supports RLUSD as a first-class settlement currency for x402-gated MCP tools, letting agents pay in a dollar-denominated unit instead of tracking XRP's price.

Frequently asked questions
Why use RLUSD instead of XRP for pricing?
RLUSD is dollar-pegged, so a price like “0.10 RLUSD per call” stays stable in real terms regardless of XRP's market price — useful for a service that wants predictable per-call economics.
Does RLUSD settle as fast as XRP?
Yes — both settle on the same XRP Ledger with ~3 second finality; RLUSD is simply an IOU currency rather than the native asset.
Where is RLUSD used live today?
SqueezeOS's premium MCP tools (/api/council, /api/scan, /api/options, /api/iwm) are all priced and settled in RLUSD.
