We seal it on-chain in ~1 second

Your content gets hashed in your browser, sealed on MegaETH, and stored permanently on Arweave. The timestamp is locked. No one can change it — not even us.

Archive to Bitcoin — the strongest permanence layer

For proofs that need the ultimate timestamp, you can anchor them directly in the Bitcoin blockchain. We embed a TSA-1 canonical manifest into a Bitcoin transaction via OP_RETURN — a tamper-proof, permanently indexed record on the world's most secure public ledger. Verifiable by anyone using any Bitcoin block explorer. No TruthStamp required. No account needed to verify.

Three ways to stamp
Pick the one that fits your situation
🌐
Public
Your content is visible to everyone. Perfect for things you want to share with the world — predictions, ideas, statements.
Best for: Creators, analysts, researchers
🔒
Sealed
Content stays hidden until a date you set. On that date it auto-reveals — with mathematical proof the sealed content existed before the reveal date
Best for: Predictions, timed reveals
🔐
Hash-only
Nothing is stored. Only the cryptographic fingerprint is recorded. Your actual content never leaves your device.
Best for: Confidential drafts, NDAs, trade secrets
Why not just take a screenshot?
Screenshots can be edited. Cloud notes can be backdated. TruthStamp can't be faked.

Quick answers
You get 10 free credits when you sign up — no card needed. Each stamp costs 1 credit for text, 2 for URLs, 3 for files. Bitcoin archive is 5 additional credits. Top up anytime from the dashboard.
Bitcoin archive is an optional extra layer where we embed your TSA-1 proof manifest directly into the Bitcoin blockchain via OP_RETURN. It's the strongest possible permanence — your proof becomes part of Bitcoin's immutable history, independently verifiable by anyone using any block explorer, completely without TruthStamp. Most users don't need it — MegaETH + Arweave is already extremely permanent. But for proofs where you want the absolute maximum, Bitcoin archive adds that final layer.
Nothing changes for your proofs. They live on MegaETH and Arweave — public, decentralized networks that exist independently of us. Your receipts are verifiable forever using open tools, even without our website. Bitcoin-archived proofs add yet another independent layer.
You can hide a stamp from public view, but the on-chain record is permanent and cannot be deleted. That's the whole point — it's tamper-proof. Once sealed, always sealed.
No. Sign up with email or Google. Connecting a Web3 wallet is optional for power users who want direct on-chain interaction — but most people never need it. Bitcoin archive requires a Bitcoin wallet (Unisat or Xverse) only if you choose to use that feature.
