Building Subgraphs on The Graph
summary
Shows how to turn contract events into a fast GraphQL backend: use the graph CLI to bootstrap a subgraph, write AssemblyScript mappings that handle Transfer events, define entities in schema.graphql, run codegen and build to compile to WASM, and deploy via IPFS to the hosted service. Demonstrates an ERC‑20 example that keeps per‑address balances, uses logging for debugging, and notes the decentralized network (launched December) already has 100+ indexers.
