About Us

Polygon (Previously Matic Network) is the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development. Its core component is Polygon SDK, a modular, flexible framework that supports building multiple types of applications. Using Polygon, one can create Optimistic Rollup chains, ZK Rollup chains, stand alone chains or any other kind of infra required by the developer. Polygon effectively transforms Ethereum into a full-fledged multi-chain system (aka Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc with the advantages of Ethereum’s security, vibrant ecosystem and openness.
