Verify in 5 seconds.

Paste any XRPL transaction hash. Get cryptographic proof of payment, ledger close time, and validator quorum. No login. No trust. No database. Just the bytes.

USE CASES

Who needs this?

💼

Freelancers

Client claims they paid. You don't see it in your wallet yet. Paste their tx hash → confirm or refute in seconds. No more "let me check with the bank" delays.

🤝

Donors & Recipients

Charity / mutual-aid / disaster relief. Donor wants proof their gift arrived. Recipient wants proof they didn't pocket it. The XRPL settles both.

⚖️

Disputes

Bridge stalled mid-flow? Counterparty says "I paid, you didn't deliver"? Drop the tx hash here and have ground truth in front of you in 5 seconds.

HOW IT WORKS

Math, not trust

✓ The XRP Ledger is the source. KV doesn't host any payment data. We fetch the tx live from the public XRPL network — same data anyone can pull from xrpl.org or any explorer.
✓ Cryptographic proof, when available. If a public XPOP watcher (XLS-41d) has cached a proof, we attach it. The proof bundles the tx + ledger + validator signatures into one verifiable artifact.
✓ Six independent checks. Structural, ledger-hash recomputation, UNL freshness, validator quorum, per-validator signatures, UNL membership. Any failure surfaces a specific reason.
✓ Verifies offline. The proof is portable bytes — drop it into any XPOP verifier (KV's, Xahau's, your own), get the same answer. No KV server in the loop.
✓ No login, no email, no fees. The XRPL is a public ledger. Verification should be too.
