Just drag, hash, and anchor. No blockchain experience required.
Tax filings, invoices, and financial records are easy to tamper with — or lose entirely. When disputes or audits come years later, proving original timing can be impossible. StampOnChain anchors the document's SHA-256 fingerprint to a public blockchain with an immutable timestamp — giving you credible evidence for regulators, courts, or clients.
Internal HR investigations and compliance policies require secure, time-locked documentation — but relying on internal systems risks manipulation or backdating. With blockchain anchoring, you gain external proof that policies or records existed exactly when claimed — even if your systems change.
Proof of delivery, customer signatures, and agent notes are critical during claims — yet PDF timestamps can be spoofed, and carriers may reject edits. StampOnChain gives your agency a trusted third-party timestamp for any document — with no need to store the file or rely on proprietary systems.
You just created a new design, poem, script, or app idea — and want to prove you had it first. But formal IP filings are slow, expensive, and public. With one click, you can anchor your idea’s fingerprint on-chain — instantly and privately. No lawyers. No uploading.
