XRPL Brief

TECH BRIEF · XRPL & CARDS

From XRPL settlement
to card authorization.

Notes for builders on the XRP Ledger: path finding, liquidity sources, issuer trust lines, webhook timing after on-ledger movement, and where card PCI scope usually ends. XRPL Brief is text only—no faucet keys, SDK downloads, or live wallet endpoints on this domain.

THE LIBRARY

Three briefs XRPL teams bookmark.

XRP liquidity & paths

Sourcing depth on-ledger and off-ledger, path payment vs direct XRP sends, and why auth amounts can drift from index during fast markets.

Ledger events & idempotency

Ordering from card processor webhooks to custodial XRPL submissions, validated ledger timing, and matching partial captures to hot-wallet balances.

Custody & card scope

Where signing keys and reserve XRP live, what never belongs in a mobile app, and how PAN handling stays outside typical XRPL wallet flows.

Scope note. Examples are illustrative. XRPL amendments, issuer rules, licensing, and PCI obligations vary by region and program sponsor. Engage qualified counsel before launch.
