New to XRP or RLUSD? Here's how to pay in 4 steps
  1. Get a wallet. Any XRP Ledger wallet works — Xaman (mobile) is a popular free one — or simply use your exchange account's send screen.
  2. Buy XRP or RLUSD on any major exchange (Coinbase, Kraken, Uphold, Bitstamp…) — you need roughly the USD price of the module, plus a little for network fees.
  3. Send the exact amount shown on this page to our address — and include the destination tag. The tag is how the ledger tells us the payment is yours; your wallet's send screen has a field for it.
  4. Your license auto-delivers. The payment verifies on-ledger within minutes and your download link appears right here on this page.

Card payments are coming soon — today checkout is crypto only. Sent a payment without its tag? It is never lost: email [email protected] with your transaction hash and we deliver manually.

Verification runs against public chain nodes every few minutes. Keep this page open after claiming — the download appears here automatically (or come back later with your order-status link, shown after you claim). Questions or a payment sent without its tag/memo: email [email protected] with your transaction hash — nothing is ever lost, we deliver manually.
