Step 1
Wallet login
Enter your Solana address and send a tiny SOL transfer. No passwords, no browser extensions.
0.0001 SOL · ~3s poll
decentralizedprivate cloud storage.
Wallet login. Client-side encryption. Encrypted blobs stored on Cloudflare R2. Your Cold Key never leaves your browser.
Secure Wallet Login
Enter your wallet address, then send a micro-payment.
How it works
Four steps. Zero trust.
Decent never sees your files or your Cold Key. You authenticate with your wallet, encrypt locally, and we store opaque blobs.
Step 2
Create a Cold Vault
Generate a 24-word Cold Key in your browser. It never leaves your device or our servers.
BIP39 seed · memory only
Step 3
Encrypt every file
Each upload gets a unique AES-256-GCM key derived from your Cold Key. Plaintext stays local.
PBKDF2 + HKDF · per file
Step 4
Store on Cloudflare R2
Only ciphertext is uploaded to Eternal Storage. Download and decrypt whenever you need it.

Cold storage encryption
Your files never leave as plaintext
Encryption runs entirely in your browser before upload. We only ever handle scrambled ciphertext — even we can't open your vault.
Cold Key in memory
A 24-word seed generates your vault master key via PBKDF2 (600k iterations). Close the tab and it's gone.
AES-256-GCM per file
Every file gets its own key via HKDF. A random IV is stored alongside metadata — never the raw key.
Zero knowledge
Lost Cold Key = lost files. That's the tradeoff for true privacy. We don't hold a backup copy.

Eternal Storage
Encrypted blobs on Cloudflare R2
After local encryption, files are stored as opaque objects in Cloudflare R2 — durable, S3-compatible storage with no plaintext ever touching our servers.

Download reverses the flow: fetch ciphertext from R2, decrypt locally with your Cold Key. Cloudflare never sees your plaintext.
