Polkadot is a layer-0 protocol and multichain network laying the foundation for the future of Web3. Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network .

Substrate-based chains are designed to seamlessly connect to Polkadot , granting access to its system of parallel transactions, cross-chain transfers, and an expanding support network.

Substrate is a completely free and open-source project . It is built using the Rust programming language, which is designed for creating fast and inherently safe software. Coordination and development of Substrate happens through public communities like GitHub and Riot, with over 100 individual contributors.
