The Graph Completes Horizon Testnet Upgrade! @GraphProtocol has officially concluded its Horizon upgrade on Testnet, its evolution from a subgraph-based protocol to a modular, multi-service data platform. With Horizon, The Graph now supports a broad range of decentralized data services, including Subgraphs, Substreams, Token APIs and more to come, all secured and powered by $GRT. For developers, this means continuity and expansion. Existing subgraphs continue to run smoothly while new real-time and analytical data services become accessible. For Indexers and Delegators, Horizon introduces simplified operations, per-service staking and delegation and eliminates the delegation tax, making participation more efficient and rewarding. The completion of the Horizon testnet is the final step before mainnet launch in December 2025, when The Graph officially becomes a home for all decentralized data services.
