Post-quantum · Multi-cloud · Tamper-evident
Your digital life,
rescued.
RESQD is a zero-knowledge vault for the things that matter most — tax returns, medical records, recovery phrases, family archives. Encrypted in your browser with post-quantum crypto, sharded across three clouds, and every access cryptographically sealed on a public blockchain. Even we can't read what you store.
No credit card. No password. Sign up with your fingerprint.
Every feature. Every tier. No gatekeeping on safety.
We never charge for security. Post-quantum crypto, multi-cloud storage, and on-chain anchoring are the same whether you're on free or enterprise.
Post-quantum encryption
ML-KEM-768 key exchange and XChaCha20-Poly1305 AEAD. Every tier, not just enterprise. When quantum computers arrive, your vault doesn't need to be migrated.
Zero knowledge, by architecture
Your files are encrypted in the browser before they ever leave your device. RESQD servers store ciphertext, wrapped keys, and opaque metadata — we literally cannot read your data.
Multi-cloud erasure coding
Every file is Reed-Solomon coded into 6 shards spread across AWS, Google Cloud, and Azure. Any cloud can disappear and your data is intact. Any 4 of 6 shards reconstruct the original.
Tamper-evident by default
Every read rotates a cryptographic canary and anchors the new commitment on Base L2. If anyone — including us — accesses a file without you, the on-chain record proves it.
Passkey-native
No passwords, no hex keys, no backup phrases. Your encryption key is derived from your passkey via WebAuthn PRF. It never touches a server and never leaves your device.
AI-agent ready
First-class MCP server for Claude and other LLM agents. Let AI tools read and write your vault under scoped, revocable credentials — without breaking zero-knowledge.
Connect Claude →Pay for capacity. Never for safety.
Every tier gets the complete cryptographic stack — post-quantum encryption, multi-cloud storage, and on-chain anchoring. You upgrade for storage, seats, and convenience features.
