zkSync, developed by Matter Labs, is a cutting-edge financial technology startup focused on enhancing the scalability of Ethereum, a popular blockchain platform. The company operates in the decentralized finance (DeFi) market, which aims to recreate traditional financial systems using blockchain technology. zkSync's primary product is a protocol that leverages zkRollup technology to scale payments and smart contracts on Ethereum.

zkRollup is a method that bundles multiple transactions into a single one, reducing the load on the Ethereum network and significantly lowering transaction costs. This makes it possible for decentralized applications (dApps) and digital wallets to handle a high volume of transactions, similar to what PayPal can achieve, but in a decentralized manner.

The company serves a diverse range of clients, including developers building dApps, businesses looking to integrate blockchain solutions, and individual users who require fast and cost-effective transactions. By focusing on user and developer experience, zkSync aims to make blockchain technology more accessible and practical for everyday use.

zkSync's business model revolves around providing a scalable, secure, and user-friendly protocol that can be integrated into various blockchain-based applications. The company generates revenue through transaction fees and potentially through partnerships with other blockchain projects and businesses. By offering a solution that is both secure and scalable, zkSync addresses two of the most significant challenges in the blockchain space, making it a valuable asset for its clients.

In summary, zkSync is a pioneering company in the DeFi space, offering a protocol that scales Ethereum transactions efficiently and securely. It serves developers, businesses, and individual users, operating in a rapidly growing market with a business model centered on transaction fees and partnerships.
