One Ecosystem. Complete Accountability.

Prove what you created, when you created it, cryptographically. SHA-256 hashing with Bitcoin timestamping via OpenTimestamps. Files are hashed client-side via WASM, they never leave your browser. We see the hash, never the content.

Every version of your work gets its own cryptographic proof, anchored to the Bitcoin blockchain. Not just a one-time snapshot, a complete, verifiable history of your creative output.

No account required for basic hashing. Drop a file, get a proof. Free accounts get a dashboard with proof history, version control, and tagging, with proofs retained for 24 to 48 hours. Paid subscriptions unlock team features, cloud storage, integrations, and long-term retention. Every proof is portable and independently verifiable via TimeAnchor or any compatible OTS tool.

A free, client-side verification tool. Verify proofs from across the Aramantos ecosystem, or check your own proofs against public ledgers like OpenTimestamps and Ethereum.

The maths is checkable by anyone. No accounts, no sign-ups, no trust required. Just cryptographic verification running entirely in your browser.

Nothing is stored, nothing is transmitted. Your proof files are read and verified locally. Even if we could see the data, a cryptographic hash reveals nothing about the original content, it is a one-way function by design.

A platform for creating and signing agreements with blockchain-verified proof of signing. Built for developers and creators who need a professional signing workflow without the enterprise overhead.

Cryptographic non-repudiation, signers can't deny they signed. Every signature is anchored to the blockchain, creating an immutable record of who signed what, and when.

SignaSeal provides the tools, templates, and signing infrastructure for creating professional agreements. The legal standing of any agreement depends on its content and jurisdiction, which you control. We provide the platform, you own the wording.

Know when your files change, and when they don't. Vigilo Verify monitors files on your terms: detect unwanted tampering, confirm expected updates have happened, or simply prove that a file has remained untouched over time.

All verification happens client-side. We never see your files. We compare hashes and tell you the result: same, or different. Whether you want change or don't want change, you'll know.

Hash-chained audit logs create an unbroken record of every check, verifiable against the Bitcoin blockchain at any time. Useful on its own, or alongside ProveChain for a complete chain of custody.
