The Graph

Substreams 0.8.0 is now live, and projects scaffolded with substreams init already use its core advantages by default. Existing Substreams modules pinned to 0.7 keep building and streaming without interruption.

• Teams can upgrade at their own pace using the published migration guide from The Graph.

vAPI Network is building on x402 to let AI agents query The Graph on demand. Its vAPI Call service lets anyone query Subgraphs through The Graph's canonical gateway and pay per query in USDC on Base — no account or API key required.

• The integration is designed for AI agents that pay per query, positioning The Graph's indexed onchain data as a directly monetizable resource for autonomous agents.
• The Graph publicly highlighted the build, tying vAPI into its push to make indexed data accessible to agents.

The Graph highlighted that Polymarket's onchain prediction markets for the current sports season — MLB playoffs, the WNBA Finals, NBA tipoff, and the NFL Sunday slate — are already indexed on The Graph Network. Developers can query the markets with Subgraphs, stream them with Substreams, or fetch data via the Token API, all without building custom indexing.

• The tweet positions Polymarket's events as readily queryable onchain data following the fall sports calendar.

Ink — Uniswap's EVM Layer 2 — is now fully streamable on The Graph via Substreams on the Extended block model. Developers can index Ink data with full call traces, native balance changes, storage diffs, and contract code changes through The Graph's pipeline.

• Extended blocks carry the deeper state data DeFi on Ink runs on, not just logs and base blocks.
• The support gives builders on Ink the same query layer with more powerful indexing underneath, without re-tooling their read layer.

The Graph Foundation is shifting from coordinator to operator and directing all Subgraph Studio traffic to The Graph Network, where Indexers who serve that traffic now earn the rewards. More query volume is coming to the network starting with BNB Chain and Polygon, part of the Foundation's new mandate to grow the network.

• 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 extended blocks are now live on Ethereum, Base, BNB Smart Chain, HyperEVM, Arc, Robinhood, Polygon, Arbitrum One, OP Mainnet, Unichain, Linea, Monad, and more, per its Supported Networks page.

Extended blocks expose internal calls, balance changes and storage changes — data that otherwise requires debug_traceTransaction, the trace_ namespace, or state-diff tracers across archive state via RPC: expensive, throttled, and often gated behind premium tiers or unavailable. The Graph's stream makes this data accessible without re-tooling the read layer.

The Graph Network supports Arc, an EVM-compatible Layer 1, from its day-one launch. Arc uses USDC as gas, making payments, FX and settlement the chain's ordinary data, and developers have two ways to index it: Subgraphs queried with GraphQL, or Substreams for real-time streaming.

Arc streams include full call-trace and state-change data through Extended Blocks support.

Subgraph support for Anubis — an EVM-compatible, privacy-focused L1 whose mainnet launched in April — is now live on The Graph Network. Anubis reports roughly $369M in TVL and 1M+ daily transactions.

Developers can index Anubis data across DeFi, RWA and payments through The Graph's subgraph pipeline and query it with GraphQL.

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 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.
