:woman_astronaut: Executive Summary

September marked a truly pivotal month for The Graph Protocol… Horizon received deployment approval from The Graph Council! Horizon contracts are now merged, and testnet deployment is imminent. On the subgraph side, Subgraph Studio and Explorer received important fixes and diagnostic tools, while indexing benefitted from the release of Graph Node v0.40.1. Adoption received a boost with eight organizations deploying subgraphs totaling 10M in query volume. Developer mindshare increased in Asia with exposure at UDC Upbit Korea and Eth India Global. Stateside, House of Web3 expanded reach with 13 events plus new visibility-boosting venue listings. Looking ahead, the focus is on Horizon’s October testnet launch, Rewards Eligibility Oracle audit, and continued UI updates to support these protocol milestones. Read on for more detail.
