StarkNet Planets Alpha - Coming to Mainnet!

The first step on our road to Mainnet is now live on testnet!
For the first time, developers can implement their business logic of choice in a smart contract and deploy it permissionlessly on StarkNet.

What is StarkNet?

StarkNet is a permissionless decentralized ZK-Rollup operating as an L2 network over Ethereum, where any dApp can achieve unlimited scale for its computation, without compromising Ethereum's composability and security.

Scalability and Integrity

StarkNet achieves scale, while preserving the security of L1 Ethereum by producing STARK proofs off-chain, and verifying those proofs on-chain.

General Purpose

On StarkNet, developers can easily deploy any business logic using StarkNet Contracts.


StarkNet will provide Ethereum-level composability, facilitating easy development and compounding innovation.

Solid Foundations

StarkNet’s foundations have been battle-tested in production.


StarkNet Contracts & the StarkNet OS itself are written in Cairo, our general computation programming language, making it easier and faster to develop, review and maintain code. Cairo has been in production on Ethereum Mainnet since July 2020.


The STARK Prover powers the StarkEx scalability engine, and has already demonstrated the ability to process 600K transactions in a single proof on Mainnet.


STARK Verifiers have been deployed on Ethereum Mainnet since June 2019. The Cairo Verifier, which can verify the proof of arbitrary business logic, has been deployed on Mainnet since July 2020.
