The Graph (@graphprotocol): Horizon Testnet Complete: On the Cusp of New Chapter

Horizon Testnet Complete: On the Cusp of New Chapter Horizon upgrade on Testnet has officially concluded, marking a major milestone in The Graph’s evolution. Horizon transforms The Graph from a network built for subgraphs into a modular data platform for many types of decentralized data services. This is all secured, powered, and paid for with GRT. This milestone validates the new multi-service architecture where Subgraphs, Substreams, Token APIs, and future data services can all operate on the same decentralized network. For developers, Horizon ensures continuity. Subgraphs keep running seamlessly while unlocking access to new data services for real-time and analytics use cases. For The Graph’s Indexers and Delegators, it simplifies operations, introduces per-service staking and delegation, and removes the delegation tax. For chains and ecosystems, it offers a unified way to bring verifiable data services to their developers, aligning growth directly with GRT economics. With the Horizon testnet upgrade complete, The Graph is now ready to scale into a multi-service data economy as GRT powers more services, users, and innovation. Mainnet is expected in December 2025.
