Huge thanks and congrats to @PinaxNetwork for building on the Extended Blocks support for @HyperliquidX EVM and their continued support of @graphprotocol and Substreams.
HyperEVM on Substreams just moved from base blocks to extended blocks support.
That means internal calls, balance changes, and storage changes in the stream, not just logs. Native HYPE that moves inside a call is now indexable via The Graph’s Substreams.
Get started: thegraph.com/docs/en/support…
New in the Pinax app: HyperEVM extended blocks.
Our Firehose and Substreams endpoints now carry every internal call, native HYPE balance change and storage write on HyperEVM, not just logs. We built the node instrumentation ourselves.

Subgraph Studio is not going away. It stays the home for managing and publishing Subgraphs. Several new and improved experience are in development… stay tuned!
Full details in the blog: thegraph.com/blog/subgraph-s…
Building through the Subgraph Studio staging environment on BNB Smart Chain or Polygon?
Publish your Subgraphs to The Graph Network so Indexers can sync them. The Foundation curates for you automatically. Do it before October 8th for a clean handoff.
thegraph.com/docs/en/subgrap…
This initiative is part of the Foundation's new mandate to move from coordinator to operator. All Studio traffic will now be directed to the The Graph Network.
The Subgraph Studio staging environment runs on a centralized Upgrade Indexer, a remnant of the hosted service. But this query volume belongs on The Graph Network - let’s send it to the network!

That's a wrap on the #ETHOnline winners: 354 submissions across three tracks and these are the standouts.
GG to every team that shipped on Subgraphs, Substreams, and The Graph's AI Tooling.
🥈 Hermes v2 ($1.5K)
Encrypted messaging for AI agents, now reasoning over live, spam-filtered DEX data from The Graph.
A new MCP server queries standardized Subgraphs (Uniswap v3, Curve, SushiSwap) and grounds a three-agent quorum in real TVL, volume, and fees.

🥇 Aqua0 ($2.5K)
One USDC deposit backing many stablecoin FX strategies on Arc, run by AI agents.
The Graph indexes the protocol, and their MCP server lets agents read liquidity, quote and swap with benchmarking strategies against 12 Subgraphs live.
ethglobal.com/showcase/aqua0…
Risk verdicts, agent marketplaces, tokenized-stock oracles. All net-new, all built on The Graph in one hackathon.
One thread left: the Continuity track. More tomorrow!
🥉 TrueTick ($1K)
Live fair-price + deviation for tokenized stocks across issuers and chains, so you can see which price is real.
Subgraphs + Substreams behind one schema, 5 venues across 4 chains. And they published their own Subgraph, not just consumed one.
ethglobal.com/showcase/truet…
🥉 presign ($1K)
Before an AI agent signs a tx, presign returns a risk verdict — plus how stale the evidence behind it was. No fresh indexed data, no green light.
An operational layer over The Graph + Substreams, shipped as a standalone MCP server.

🥈 Turnstile ($1.5K)
Pay-per-call onchain analysis for AI agents: sell the answer, keep the method.
An ERC-8004 Substreams module in Rust normalizes 197 agent registrations across 4 networks, and a Uniswap analyst reads live data through Subgraph MCP.
ethglobal.com/showcase/turns…
🥇 Covenant ($2.5K)
A bonded watch over a DeFi lending position — it posts a bond and pays the borrower if it ever misses an evaluation.
One GraphQL query runs across 13 protocols and 19 deployments. Ships an MCP server + SKILL.md and pays The Graph over x402.

#ETHOnline Winners, Part 2: Best AI Tooling or AI Use Case with The Graph — built from scratch.
Our biggest bounty of the three ($6K), and it was close. 🧵
Three builds, one theme: Standardized Subgraphs turn "integrate each protocol" into "add a row."
Next up: Tomorrow we will highlight Best AI Tooling built from scratch on The Graph.
🥉 OpenBook ($1K)
A data marketplace for AI agents with a freshness guarantee that enforces itself.
Every delivery is stamped with _meta{block} — if the data's stale, the onchain escrow refunds the buyer. Any of 15k+ active subgraphs becomes a monetized market with one line.

🥈 Sentinel ($1.5K)
A confidential oracle that spots hidden cross-protocol leverage before it cascades.
Joins 9 subgraph deployments on Account.id inside a TEE. Project scanned 37,862 accounts and surfaced ~$35.9M of debt levered across protocols on the same collateral.
