Is the settlement actually final? Prove it.

Engine ready

Every button below runs the real Finalis certifier — it takes the legs of a cross-ledger settlement (XRPL, EVM, notary), evaluates each against an explicit, versioned finality policy, and issues a certificate that is FINAL only if EVERY leg is final — otherwise WITHHELD with the exact reason. Certificates carry a tamper-evident digest, and a previously-final certificate is CONTESTED if later evidence (a reorg) contradicts it. Fail-closed; deterministic; nothing broadcast.

Certify, verify, contest — end to end

Each button drives a different real operation on a 3-leg settlement: XRPL (28-validation finality policy), EVM (12-confirmation / max-2-reorg policy), and notary (2-of-3 attestation policy). The engine, not this page, computes every result.

Settlement XRS-0471 · 3 legs · XRPL 28-validation policy, EVM 12-confirmation / max-2-reorg policy, notary 2-of-3 policy.
Certify evaluates every leg and issues FINAL only if all pass. Withheld if any leg is pending, at-risk, or notary-invalid. Verify recomputes the digest to detect tampering. Contest revokes a previously-final certificate on new evidence.
