# Underlying tech

Bit Protocol is built on **Oasis Sapphire**, the first confidential EVM in the Ethereum ecosystem — combining high throughput, low gas fees, and powerful privacy features. This technical foundation is what enables bitUSD to operate securely, efficiently, and in a way that protects user data without compromising on DeFi usability.

Understanding how Bit Protocol leverages Sapphire helps clarify what makes this platform different — especially when it comes to future-proof privacy and seamless omnichain expansion.

## Key features

* **EVM Compatibility**: Enables omnichain functionality and facilitates easy migration from other EVM networks to Bit Protocol, expanding the user base and market reach without compromising privacy.
* **Private Storage and End-to-End Encryption**: Sapphire's encrypted storage is vital for Bit Protocol, securing the privacy of transactions involving bitUSD.
* **Encryption Precompiles**: These precompiled contracts enable secure, efficient cryptographic operations, ensuring the integrity and security of transactions within the Bit Protocol ecosystem.
* **Free View Calls**: This feature enhances user experience and reduces operational costs, allowing the development of sophisticated financial tools within the DeFi space.
* **Web2 Authentication Integration**: Support for advanced authentication methods offers the potential to enhance user accessibility and trust, and facilitate mainstream adoption.

### Main Benefits

* **Enhanced Privacy and Security**: Central to Bit Protocol, Sapphire’s privacy-centric architecture ensures secure financial transactions and data protection.
* **Development and User Adoption**: EVM compatibility and a developer-friendly environment enable rapid innovation and growth, attracting users from other blockchain ecosystems.
