name: Polkadot description: Polkadot is a multi-chain blockchain network that enables interoperability between specialized blockchains called parachains. Developer APIs are provided through Subscan (a multi-chain block explorer with a hosted HTTP API) and the Substrate API Sidecar (a REST interface for Polkadot SDK-based chains), enabling queries against extrinsics, events, accounts, blocks, staking data, and parachain state on Polkadot, Kusama, and related networks. deliveryModel: model: open-core license: GPL-3.0 open_source: true commercial: true callable_host: false label: Open core · an OSS project plus a commercial hosted product confidence: high source: -
