How It Works
1. Fingerprint
Your document is processed locally. We only use its unique digital fingerprint — the file never leaves your device.
2. Stamp
The fingerprint is anchored on a public blockchain. An immutable proof of existence is generated instantly.
3. Verify
Anyone with the original file can verify its authenticity and integrity in seconds.

Built for Developers
Integrate blockchain certification into your application with less than 10 lines of code.
import { RootsureClient } from "rootsure-sdk";
// Session via email + password (or JWT in RootsureClient)
const client = await RootsureClient.fromPassword({
email: process.env.ROOTSURE_EMAIL,
password: process.env.ROOTSURE_PASSWORD,
});
// SHA-256 locally, then register for batch / Cardano stamp
const result = await client.registerFile("./contract.pdf", {
type: "legal",
});
console.log(result.hash, result.message);
// → { success, hash, timestamp, message }Plans
