Proofledger

Proof of reserves and redemption solvency, proven from chain state — not a balance sum

Reconstructs circulating supply from trustline state; separates redeemable-now from frozen liability; checks clawback recoverability and XRP owner-reserve solvency — then renders a PASS / WARN / FAIL verdict, exact-decimal, zero network calls.

✓Adversarially audited · 3 public provenance cards · 100% mutation-kill · signed wallet attestation — verify the proof →

What you get

A plugin, not a platform — drop it into your own stack. You receive a self-hostable module plus a hosted JSON API and its OpenAPI spec, so you compose Proofledger into your product instead of rebuilding this layer.
