Paste a verifiable trade document (eBL, invoice, letter of credit, certificate) or its merkleRoot. We re-derive its cryptographic hash and confirm it was anchored across 5 blockchains at once (XDC, Base, Hedera, XRP Ledger & Stellar) via ProofRail — no account needed. This is the same OpenAttestation / TradeTrust standard used by SBI, Singapore & ITFA.
