Bitcoin × Ethereum

Supercharged by ZK Tech

Starknet fuses Bitcoin’s integrity and Ethereum’s utility to unleash a whole new DeFi experience.

Unlimited Scale

Starknet utilizes the power of STARK technology to ensure computational integrity. By validating off-chain transactions with advanced math and cryptography, Starknet overcomes Ethereum’s scalability limitations. Starknet is a Validity Rollup that provides unlimited scale while retaining Ethereum’s security and decentralization.

How Starknet Works →

Superior UX

Starknet offers efficient and user-friendly experiences by employing Native Account Abstraction. All accounts are smart accounts: their behavior is determined by their developers rather than at the protocol level. This means unparalleled flexibility in account management. Developers can customize their applications beyond protocol constraints to elevate user experience and security.

Developer Hub

Starknet is home to the fastest-growing Layer 2 (L2) developer community due to its novel approach to scaling Ethereum and making it economically feasible to build even the most complex dApps. The Developer Hub provides a variety of manuals and resources for builders, by builders, on how to get started on Starknet.

Creativity Unleashed

Starknet devs are empowered to code solutions that make a difference. Cairo, Starknet’s native smart contract language, allows developers to push the boundaries of their applications by allowing them to code any kind of business logic. Building with Cairo, developers can let their vision reach its full potential on Starknet.

Upcoming Events

14 - 16 May, 2025 · Toronto, Canada

Consensus 2025 Toronto

Since 2015, Consensus has been more than an event–it’s the annual gathering of the tribes. It’s where the most influential voices in blockchain, Web3, and AI come together to drive innovation forward.

In 2025, Consensus brings its flagship event to Toronto, where the world’s first Bitcoin and Ethereum ETFs were born. As North America’s third-largest tech ecosystem and second-largest financial hub, Toronto unites global innovation with transformative technology leadership.

Built on CoinDesk’s foundation of independent, unbiased journalism, Consensus Toronto will weave together breakthrough technologies, from digital assets to artificial intelligence, fostering the collaborations that define what’s next.

Starknet 🧡 Bitcoin

Starknet is working hard to integrate with Bitcoin in the same way that it already integrates with Ethereum to become the first dual settlement L2.

​Come join us and learn how Starknet plans to do this integration and the benefits it will bring for Bitcoin, Starknet and even Ethereum.

​We will have a couple of talks from StarkWare and the Starknet Foundation and plenty of time for you to have one on one conversations.

Eth Prague

ETHPrague isn’t looking for the next get rich quick scheme or groundbreaking DeFi apps. Instead, it’s an event focused on the future of Ethereum and potential concepts or applications that don’t yet exist.

We want to tackle challenges that could arise in the next decade because we believe Ethereum will play a major role in solving economic, social, and environmental problems. The future is in your hands, anon! You decide whether we end up living in a dark, authoritarian dystopia or a bright, solarpunk utopia.
