ZKsync, developed by Matter Labs, provides open-source blockchain technology for organizations building scalable applications and digital asset services. Its ZK Stack is a customizable framework for creating enterprise-grade zero-knowledge (ZK) blockchains that settle on Ethereum, inherit its security, and can interoperate with one another. Organizations can configure features such as gas tokens, transaction fees, data availability, privacy, and permissioning to suit their needs.

The platform is designed for high throughput, low transaction costs, and rapid deployment. Matter Labs offers rollup-as-a-service to host and operate blockchain infrastructure, alongside enterprise-grade support for teams that prefer to manage their own chains. The broader product portfolio includes Prividium, Airbender, and digital asset advisory services. ZKsync also supports use cases across fintech, including cross-border payments, tokenized deposits, treasury management, and intraday repo. Its ecosystem includes projects in consumer applications, decentralized trading, fund management, gaming, and entertainment. Developers can access documentation, quick-start resources, support, and community channels.
