The Graph Protocol is an open-source decentralized network designed for querying and indexing blockchain data across platforms like Ethereum, IPFS, and Polygon. It allows developers to create and publish open APIs, known as subgraphs, enabling efficient data retrieval. The project is organized as a Yarn workspaces monorepo with packages including smart contracts for the protocol, TypeScript SDKs, and shared linting configurations. Development requires Yarn v4 for dependency management and a systematic versioning approach using changesets. The Graph encourages community contributions through issue creation and pull requests, with active discussion in The Graph Discord and Forum. Security concerns are addressed via The Graph’s bounty program on Immunefi, and the entirety of the project is licensed under the GPL license.
