# Security & Cryptography

#### **What kind of encryption does Cryptic use?**

Cryptic uses post-quantum cryptography (PQC) based on NIST-selected standards, including:

* ML-KEM-768 (Kyber) for secure key exchange
* ML-DSA (Dilithium) for digital signatures

These algorithms are designed to remain secure even against future quantum computers.

***

#### **Why is post-quantum cryptography important?**

Quantum computers are expected to break widely used encryption standards in the coming years. Leading institutions including NIST and NSA have mandated migration to post-quantum cryptography by 2030.

Cryptic is built with post-quantum security from day one, rather than relying on future upgrades.

***

#### **Are messages end-to-end encrypted?**

Yes. All messages are encrypted end-to-end using Cryptic’s post-quantum cryptographic stack. Only the intended participants can read message content.

***

#### **Does Cryptic collect metadata?**

Cryptic is designed to minimize metadata exposure. There is no centralized custody of user keys or message content, and privacy is a core architectural principle rather than an afterthought.

***

#### Wallet & Payments

Is Cryptic custodial?

No. Cryptic is fully non-custodial.

Users retain complete control over their private keys, assets, and identity at all times.

***

#### Where are private keys stored?

Private keys never leave the user’s device. They are stored using OS-level hardware-backed secure storage:

* iOS Secure Enclave
* Android Keystore

Optional biometric protection can be enabled.

Cryptic cannot access, export, or recover user keys.

***

#### Can I send crypto inside chats?

Yes. Cryptic enables chat-native payments, allowing users to send and receive tokens directly inside conversations without switching apps or copying wallet addresses.

***

#### Which blockchains does Cryptic support?

Cryptic currently supports Solana high-speed, low-cost on-chain execution, with multi-chain expansion planned. The architecture is designed to support additional networks as the platform evolves.

***

#### Does Cryptic support DeFi features?

Cryptic is built with DeFi extensibility in mind. Over time, features such as swaps, OTC flows, and automation may be integrated directly into the platform experience.
