The Graph

HyperEVM on Substreams moved from base blocks to extended blocks support, with the work credited to Pinax Network, which The Graph publicly thanked for building on the feature and for its continued Substreams support. The stream now carries internal calls, balance changes, and storage changes, not just logs.

• Native HYPE that moves inside a call is now indexable, opening up deeper analysis of Hyperliquid's EVM chain.
• The expanded stream data lets developers trace value flows and contract internals on HyperEVM through The Graph's Substreams pipeline.

The Graph Foundation is shifting from coordinator to operator and directing all Subgraph Studio traffic to The Graph Network. More query volume is coming to the network starting with @BNBCHAIN and @0xPolygon, part of the Foundation's new mandate.

• Developers using the Subgraph Studio staging environment on BNB Smart Chain or Polygon are asked to publish their Subgraphs to The Graph Network before October 8th so Indexers can sync them and the Foundation curates automatically for a clean handoff.
• Developers already publishing and querying on The Graph Network need no action — their Subgraphs stay live and keep serving queries.
• The Studio staging environment still runs on a centralized Upgrade Indexer, a remnant of the hosted service, which this initiative phases out.

The Graph announced the winners of its prize tracks at ETHOnline, where it logged 354 submissions across its tracks and was the most widely used technology at the hackathon. Alpha Markets took first ($2.5K) in Best Use of Composable or Standardized Graph Products: a prediction market where AI analysts publish protocol financials and stake USDC on their conclusions, with one query running unchanged across 28 Ethereum lending deployments.

• Sentinel placed second ($1.5K) — a confidential oracle that scanned 37,862 accounts and surfaced ~$35.9M of debt levered across protocols, running 9 subgraph deployments inside a TEE.
• OpenBook placed third ($1K) — a data marketplace for AI agents whose onchain escrow refunds buyers if delivered data is stale, monetizing any of 15k+ active subgraphs with one line.

The Graph Network now supports Arc, an EVM-compatible Layer 1, from its day-one launch. Developers can publish Arc Subgraphs and query them with GraphQL, and stream Arc data in real time via Substreams with full call-trace and state-change data through Extended Blocks support.

The Graph Network now supports Subgraphs for Anubis, an EVM-compatible, privacy-focused L1 whose mainnet launched in April. Anubis reports roughly $369M in TVL and 1M+ daily transactions.

Developers can now index Anubis onchain data through The Graph Network's subgraph pipeline.

The Graph announced that Substreams — its parallelized indexing engine with multi-sink output — can now serve indexed data back over GraphQL. This lets teams keep the same query interface The Graph is historically known for while getting Substreams' more powerful indexing underneath.

• Substreams provides parallelized indexing and multi-sink output.
• The new capability serves that data back through GraphQL, so developers don't have to re-tool their read layer when outgrowing a Subgraph.
• Same familiar query layer, more power underneath.

The Graph launched a set of open-source Substreams Skills that let AI coding assistants (Claude Code, Cursor, and others) turn a plain-language prompt into a working blockchain data pipeline in minutes, instead of days of hand-written Rust.

• Skills cover EVM ABI decoding, Solana account models, Bitcoin UTXO, SQL sink selection, testing, deployment, and the Portal API, including dev, ethereum, solana, bitcoin, convert-sql, sink, sink-deploy-local, hosted-sink, and testing.
• A dedicated substreams-convert skill maps an existing Subgraph's schema.graphql entities to protobuf types and its AssemblyScript handlers to map and store modules, carrying initialBlock over — so a Subgraph hitting its limits becomes a stream that can be sunk anywhere.
• A companion machine-readable OpenAPI spec for the Substreams registry lets agents find packages without scraping HTML.

The Graph introduced the Subgraph MCP (Model Context Protocol), which lets AI agents drill down into onchain data. A sequence of four calls takes an agent from a protocol name to a live query: search subgraphs by keyword, get deployment 30D query counts, get schema, and execute query.

The Graph (via StreamingFast) introduced Hosted Stores, a managed, block-aware key/value store for Substreams modules. It lets a module look data up mid-stream without recomputing it on every block, and is reachable over gRPC or as a store input.

Hosted Stores removes the need to maintain a self-hosted store sidecar when a Substreams module needs on-chain lookups while executing, cutting infrastructure overhead for pipelines that previously had to fetch or re-derive state across blocks.

The Graph Foundation published Part 2 of its technical roadmap series, officially announcing the Foundation's new mandate and how it will bring the roadmap to life. Part 1, published earlier this year, laid out the technical future of The Graph; this second installment focuses on the Foundation's role in executing it.
