Sign in — or create your Vault.
Enter your work email. If you already have a Vault we'll send you straight in; if you don't, this creates one. A one-time link is dispatched — no password is ever held — then an authenticator code opens the Vault. Per-tenant isolation is enforced at the database engine. The Vault is in beta and enters general institutional release in Q3 2026.
What this Vault storesOnly your evidence records (each ~1 KB of JSON: timestamp, signature, salted hashes, anchor metadata). Never your documents. Never your filenames unless you choose to attach one. The Vault holds commitments, not content — it is not a discoverable trove.
Step 2 of 2 · Two-factor
Secure your Vault.
Your Vault holds tamper-evident evidence. A second factor is required to open it — a one-time code from your authenticator app.
Scan this with Google Authenticator, 1Password, Authy, or any TOTP app:
Can't scan? Enter this key manually:
Why two factorsAnyone who reaches your Vault can read your compliance posture. The email link proves the address; the authenticator proves the device. Both are required to open the Vault — by design. On Enterprise, your admin can enforce this org-wide via SSO/SAML, and mandate it for crypto-shred and key rotation.
⚠ Two-factor setup didn't finish on this sign-in. Sign out and back in to complete authenticator enrollment. If it keeps happening, emailsecurity@ledgerproofhq.io.
Your Vault.
Evidence persists indefinitely. Verification proceeds independently of LedgerProof's continued operation — delete us tomorrow and every receipt still verifies against Bitcoin.

Your AI systems
Each registered AI system is one unit of Article 50 scope — and the unit your plan is measured in. Register the systems you want under continuous proof.

Attestation —
Article 50(3) and 50(4) can't be read from your site — you attest to them. Your answers update this system's posture and appear in its dossier.
You've reached your plan's system limit.
Upgrade to put more AI systems under continuous proof.
Capture evidence straight from your code. pip install ledgerproof, attach a free adapter (OpenAI · Anthropic · Mistral · Google · LangChain), and every AI output anchors automatically. Free for development — the SDK and adapters are open-source (Apache-2.0).
Billing & plan
View invoices, update your payment method, change plan, or cancel — anytime, through the secure Stripe customer portal. Billing is per registered AI system; seats are free and unlimited in-tier.
Invite teammates into a shared Vault with role-based access, SSO/SAML, and org-wide 2FA enforcement. Seats themselves are free and unlimited in-tier — your plan is measured per registered AI system, never per seat. Team workspaces are a premium add-on on Team plans and above.
The Vault is in beta. During the institutional evaluation window, attestations are issued through the publisher portal at publish.ledgerproofhq.io. On public release, evidence issued through the Protocol — and continuous Article 50 scans from the readiness cockpit — will appear here, indexed by system, ISO timestamp, content hash, and Bitcoin anchor block.
A Stream is an append-only series of receipts — one transparency log per thing you prove. Your AI systems are Streams; so are document sets, contracts & bids, and agent runs. Pick one to filter the receipts below; the count shows confirmed / total.
Your Vault is empty.
When you issue evidence above, it appears here. Records are append-only and gap-evident — they cannot be edited or silently removed, by you or by us. Crypto-shred (GDPR erasure) destroys the content while the proof-of-existence survives.
