# Paradex Chain

Paradex Chain is a dedicated application chain built on the Starknet Stack, combining the performance of a purpose-built blockchain with full compatibility with the Starknet ecosystem. Developers can deploy smart contracts, access Paradex's deep liquidity infrastructure, and build on a chain designed for privacy and speed.

#### [Starknet Stack](/chain/paradex-chain-introduction)

Built on the CairoVM with full Starknet compatibility. Deploy existing Starknet contracts by simply updating RPC endpoints.

#### [Deep Liquidity Access](/chain/paradex-chain-introduction)

Seamlessly interact with the deep liquidity on the Paradex Exchange directly from the chain.

#### [Privacy by Default](/chain/security/security-lockdown)

Encrypted state diffs with ZK verification posted to Ethereum. Custom RPC masking protects all position and account data.

## Getting Started

## Security & Trust

Paradex maintains robust security practices to protect user funds and ensure the integrity of the chain.

#### [Security Lockdown](/chain/security/security-lockdown)

Controls for managing fund security including L1 deposit blocking and withdrawal limits.

#### [Guardian Keys](/chain/security/guardian-keys)

Multi-party key management system that safeguards critical chain operations.

#### [Audits & Pentests](/chain/security/audit-pentests)

Regular security audits and penetration testing by independent firms to ensure platform integrity.

#### [Bug Bounty](/chain/security/bug-bounty)

Responsible disclosure program rewarding security researchers who identify vulnerabilities.
