# Cryptography

Strovum is built on a **cryptographically secure, EVM-compatible foundation**, combining enterprise-grade security with Web3 usability.

#### Why Base

Strovum is deployed on **Base**, Coinbase’s Ethereum Layer-2 network:

* **EVM Compatibility:** Supports Solidity and Ethereum tooling for seamless contract deployment.
* **Optimistic Rollups:** Fast, low-cost transactions with Ethereum-level security.
* **Regulatory Alignment:** Institutional credibility and compliance by design.
* **Gasless Transactions:** Fee-free onboarding, airdrops, and seamless in-app operations.

#### Why EVM

* **Cross-Chain Interoperability:** Supports future bridging to Ethereum, Avalanche, BNB Chain, and Solana via adapters.
* **Smart Contract Portability:** Reusable, modular Solidity contracts accelerate development.
* **Ecosystem Access:** Leverages mature developer tooling, audits, and infrastructure providers.

#### Core Cryptography

* **Public Key Cryptography:** Non-custodial key management and transaction authentication.
* **Hash Functions (SHA-256):** Data integrity and smart contract verification.
* **Zero-Knowledge Proofs (ZKPs):** Privacy-enhancing proofs for sensitive transactions.
* **End-to-End Encryption:** Chat messages, media, and files encrypted at rest and in transit.

#### Message & Intent-Centric Architecture

Strovum embeds financial actions within the chat layer:

* **Example:** “Send $50 in USDC to Carlos” is executed directly within the chat.
* **Intent Engine:** AI maps natural language to blockchain transactions securely.

#### API Integration

Secure, modular APIs connect Strovum to:

* **Coinbase, Transak, Stripe, MoneyGram** for global on/off-ramps
* **Chain Aggregators** for swaps and bridging
* **Compliance APIs** for KYC, AML, and audit standards

All integrations maintain **non-custodial control**, ensuring users’ keys and assets are never stored on Strovum.

#### Legal & Regulatory Framework

* **Non-Custodial Wallets:** Users retain full asset control.
* **No Money Transmission:** Fiat handled by licensed partners.
* **Tiered KYC:** Applied only where required for fiat or high-volume usage.
* **Secure Logging:** Audit trails maintained without compromising privacy.

#### Conclusion

Strovum combines technical rigor with user-first design. Using **Base**, EVM standards, encryption, intent recognition, and secure APIs, the platform removes blockchain complexity while giving users full control and a seamless, intuitive experience.
