Step 1 · ~15s
🔑 Enable co-signing (BYOK)
Generate your Ed25519 keypair in the browser. Velaru never sees your private key. Register your public key — from this point, every receipt needs both signatures.
Paste your Copy Receipt JSON at the public verifier. Checks run client-side — Velaru cannot alter the result. Look for CHECK 4b (your signature) and CHECK 5b (RFC 3161).
After verification passes, download the FRE 707 Verification Affidavit — includes dual-signature section when co-signing is active. Hand to legal or drop in a diligence packet.
