Vanishd witnesses your deletion and revocation claims. We don't delete for you. We anchor your privacy-preserving attestations to a tamper-evident audit trail.
Vanishd provides independently verifiable third-party attestation receipts for your deletion and revocation claims. That's all we do. We create cryptographic receipts for every credential you destroy, revoke, or expire—certified via our simple API & developer-first protocol.

API
Hash your data client-side. Send us the hash. Receive a blockchain-anchored receipt. Your secrets never leave your infrastructure—we only see cryptographic hashes.

import { Vanishd, generateSalt, hashCredential } from '@vanishd/sdk';
// Initialize client with your API key
const vanishd = new Vanishd({ apiKey });
// Generate salt (store it in YOUR database)
const salt = generateSalt();
// Hash with salt, then certify the deletion or revocation
const hash = await hashCredential(credentialId, salt, apiKeyId);
const receipt = await vanishd.certify({ credentialHash: hash });Anyone with a copy of your receipt can independently verify your hashed claim.
3rd-Party Auditors can 1-click verify your tamper-evident receipts as proof of deletion or revocation. No API key required—full transparency and simple by design.
// Anyone can verify—no API key needed
const proof = await Vanishd.verify(receiptId);
console.log(proof.valid); // trueTransparent Pricing
All receipt types priced the same. Deletion, revocation, agent termination.
