The Public Testnet for Paradex Chain is now live.

Built on the SN Stack, Paradex Chain is a general-purpose smart contract platform powered by CairoVM. It shares state with Paradex Exchange, enabling a fully composable, high-throughput execution environment where on-chain applications can seamlessly interact with the deep liquidity infrastructure we’ve built over the past year.

Technical Bits

The CairoVM is a specialized virtual machine designed specifically for Validity Proof systems (ZK-Rollups), and is free from the constraints of EVM-based architectures. Smart contracts are written in Cairo, a Rust-like language designed to maximize the efficiency of STARK-proof-based computation for scaling Ethereum. Effective immediately, Cairo developers get:

Full Starknet Compatibility: Deploy your SN contracts by simply updating RPC endpoints

Simplified Deployment: No protocol-level changes required

Mature Tooling: Use all existing Starknet ecosystem tooling including Hardhat, Starkli etc.

Ping the #developers channel on Discord for gas and Testnet USDC. We will release a dedicated faucet shortly.

All dev teams building on Paradex Chain are henceforth part of the ParaCabal. You are encouraged to fire ze missiles, and share your shii*t in #developers on Discord. If it breaks, well… we have more missiles.
