The Graph

The Graph's Rewards Eligibility Oracle (REO) is two months in, having run three eligibility steps in nine weeks. It directs indexing rewards toward Indexers that actually serve end consumers; the latest step removed under-performing Indexers, cutting the eligible set from 70 to 55. After the first two months, indexing rewards go only to Indexers that serve queries, and the daily bar rose from 1 to 5 to 10 Subgraphs.

• The next step, announced for November 17, shifts focus from Indexer counts to stake: Indexers must index the greater of 10 Subgraphs or 1 Subgraph per 4M GRT staked, a change affecting only Indexers above 40M GRT. The end goal is 1 qualifying Subgraph per 1M GRT.
• Context for the change: the 10 largest Indexers hold ~70% of total stake and received ~71% of indexing rewards from Aug 2 to Oct 29.
• REO publishes its rules and open-source logic, runs on a fixed daily schedule, and treats every Indexer as eligible if the oracle stops posting for seven days.

The Graph highlighted a Substreams performance milestone: the same Uniswap v4 data on Ethereum indexed in 7 minutes 36 seconds using 75 parallel workers — down from 23 hours. The work was credited to the StreamingFast team.

Alpenglow — Solana's new consensus protocol cutting finality from ~12.8 seconds to ~150ms — is live on mainnet, and The Graph says Solana Substreams is already up to date with it. StreamingFast prepared Solana Substreams for Alpenglow ahead of the switch so developers' blockchain data pipelines keep running through the upgrade.

• The compatibility work means indexers and data apps can keep streaming Solana data without interruption as the network's consensus changes take effect.
• The Graph points builders at the 150ms-finality environment for new applications.

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.
