Powering Scalable Self-Custodial Transactions

In Production on Mainnet
StarkEx is a battle-tested L2 scalability engine, deployed on Mainnet since June 2020. It has since supported a wide range of use cases: spot trading, perpetual trading, and NFT minting and trading.

Scalability & Computational Integrity
Several applications rely on StarkEx and the underlying STARK infrastructure to scale while ensuring computational integrity. Thanks to the SHARP (Shared Prover) technology, gas costs are amortized across all StarkEx-base applications.

ZK-Rollup, Validium, and Volition
StarkEx can be deployed in either ZK-Rollup mode (publishing data on-chain) or Validium mode (verifying data-availability with a sidechain). Coming soon: Volition - allowing users to choose for themselves data-availability mode.

Cairo-Based - General Computation
StarkEx is written in Cairo, our Turing complete programming language. Cairo is designed for general computation and as such allows developing scalability solutions to any business logic in a more efficient and secure way.

StarkEx, already deployed on Mainnet, will be also deployed on StarkNet, our coming up decentralized permissionless ZK-Rollup platform.

Wallet Integration
Wallet support is fundamental to StarkEx success. We offer native support with Ledger (Nano S and Nano X), as well as with Authereum and WalletConnect. We also offer MetaMask integration via Web3-compatible key generation (applies to many other existing wallets).

Trustless Scalability

Leveraging ZK-STARK technology, StarkEx drastically reduces gas cost per transaction without requiring any trust assumptions by the users.


Designed to power self-custodial dApps, StarkEx employs innovative anti-censorship mechanisms to ensure that users’ funds are always in their custody.

Production-Grade and Flexible

StarkEx is live on Ethereum Mainnet, providing a robust and secure scaling solution to a wide range of decentralized exchanges, including spot trading, derivatives, and NFTs. AMM support is coming soon.

StarkEx can be deployed in either ZK-Rollup mode (on-chain data), or Validium mode (off-chain data).

One STARK to Rule Them All

StarkEx is written in Cairo, our Turing-complete language that is fully integrated with the STARK proof system. This allows StarkEx to serve any business logic easily and frictionlessly.

The computational integrity of all Cairo program executions is verified by a single Verifier smart contract, thus offering dApps greater security and shorter time-to-market.
