Core Architecture

Four Pillars of USB Vault Resilience

1. $0 Hardware Freedom

Never be trapped by supply chain delays or expensive replacements. Any generic USB thumb drive becomes an air-gapped cryptographic vault.

2. <60s Instant Recovery

Your cryptocurrency stays on the blockchain, not on the USB. Type your 12-word recovery phrase to recreate your vault on a replacement USB in seconds.

3. Encrypted Vault Cloning

Keep duplicate encrypted .royivault files in safe physical locations. Vault files are AES-256-GCM encrypted and impossible to open without biometrics/PIN.

4. Air-Gapped Signing

Your private signing keys are loaded into RAM strictly during local authorization, sign the transaction payload offline, and wipe clean instantly.

FAQ

Frequently Asked Questions

Everything you need to know about ROYI Cold Storage architecture, recovery, and security guarantees.

Is my cryptocurrency stored directly on the USB drive?

No. In all blockchain networks, cryptocurrency tokens live on the public blockchain ledger (Apertum EVM Subnet). Your USB drive stores only the encrypted private signing key needed to authorize outbound transactions.

What happens if my USB drive fails or is lost?

Your funds are 100% safe. Because your assets are on-chain, you can plug in any spare USB drive, click Restore from Recovery Phrase, and type your 12-word BIP-39 seed phrase. Your cold wallet vault will instantly be restored on the new USB for $0.

How does biometric protection work with my USB?

ROYI integrates WebAuthn / TPM hardware security modules built into modern computers and phones. When authorizing a transaction, you can authenticate using Windows Hello, Apple TouchID/FaceID, or Android fingerprint sensors alongside your vault PIN.

Can I monitor my cold wallet balance while the USB is unplugged?

Yes! When you set up your cold wallet, the public address is saved in watch-only mode in your ROYI Web Wallet. You can check balances, view incoming deposits, and generate receiving addresses without plugging in your USB.

What encryption algorithm protects the USB vault?

The USB vault file (`.royivault`) uses PBKDF2 key derivation with 100,000 iterations and authenticated AES-256-GCM encryption (WebCrypto API). Even if someone physically steals your USB drive, they cannot decrypt the private keys without your biometric signature or Master PIN.
