The Graph

$15,000

About

The Graph is the indexing and query layer of web3, giving developers and AI agents structured, real-time access to blockchain data across 50+ networks. Build with Subgraphs, Substreams, the Subgraph MCP, and more.

At EthGlobal Lisbon, The Graph is awarding $15,000 across three tracks.

In the AI Tooling track, prizes are $3,000 (1st), $2,000 (2nd), and $2,000 (3rd).
In the other two tracks on Best AI Use Case and Best Use of Composable/Standardized Graph Data Products, prizes are $2,500 (1st), $1,500 (2nd), and $1,000 (3rd).

Build a tool that makes The Graph easier to use from AI environments like Claude, Cursor, and ChatGPT. Think reusable infrastructure, not a single app: new or extended MCP servers, agent SKILLs, x402 payment tooling, A2A integrations, framework plugins, or one-click client configs. Featured challenge from the Substreams team: use the Substreams SKILLs to deliver the best one-prompt deployment, going from a single natural-language prompt to a working, deployed Substreams pipeline.

Examples:

A one-prompt Substreams deployment flow using the Substreams SKILLs
A cross-protocol MCP that fans one query across every protocol on a shared standard schema
A layered MCP that unifies several Standardized Subgraph schemas behind one agent interface
A reusable agent SKILL that stands up a new cross-protocol MCP in minutes
A project built on Nuthatch, extending its MCP tools, adding new SKILLs, or wiring its output into an agent workflow.
New integrations with web3 protocols (e.g. a SKILL/MCP integrated with Chainlink's AI tooling)
A SKILL paired with the Subgraph MCP that turns multi-Subgraph queries into market research or blog posts

Judging criteria: Usefulness to other builders (30%) · Reusability & completeness (25%) · Effective use of The Graph (20%) · Technical execution (15%) · Innovation (10%)

Qualification Requirements

Submit reusable tooling or infrastructure (MCP server, SKILL, plugin, client config, or payment tooling), not a single end-user app.
The tooling must work against live blockchain data, whether from a Graph provider (for example Subgraph Studio for Subgraphs or The Graph Market for Substreams) or a self-hosted indexer such as Nuthatch. Purely mocked or static datasets do not qualify.
Open-source the code with a clear README or SKILL.md.
Extending or improving an existing tool is welcome if clearly additive.
Submit a public repository and a 2–4 minute demo video.

Build an AI agent or application that uses The Graph as its live source of blockchain data. Rewards research assistants, trading/execution agents, portfolio copilots, risk monitors, and more. Query 15,000+ Subgraphs through the Subgraph MCP, stream data with Substreams, or let your agent pay per query with x402.

Examples:

A DeFi research agent answering natural-language questions via the Subgraph MCP
A trading/execution agent reading live liquidity data and paying per query with x402
A portfolio/PnL copilot reading balances, transfers, and swaps across chains
A risk-monitoring agent watching lending positions for liquidations
A governance assistant summarizing DAO proposals and voting activity
A dapp-embedded chat copilot grounded in live Subgraph data

Bonus: extra credit for teams that also ship a reusable SKILL or MCP server.

Judging criteria: Effective use of The Graph (35%) · Usefulness & impact (25%) · Technical execution (20%) · Innovation (10%) · Demo & clarity (10%)

Qualification Requirements

Use The Graph as a load-bearing source of blockchain data (Subgraphs, Subgraph MCP, or Substreams).
Consume live data from a Graph provider. Mocked or static data does not qualify.
Include an AI/agent component that reasons over or acts on the data, not just prints a raw query result.
Submit a public repository and a 2–4 minute demo video.
Briefly describe how The Graph is used (which Subgraphs, endpoints, tools).
Build the project during the event; open-source starter kits are fine.

Build on The Graph's composable and standardized data products. Use Standardized Subgraphs (one shared schema across every protocol of a type) to run a single query across many protocols, compose reusable Substreams packages into new pipelines, or layer the Subgraph MCP for cross-protocol analysis. New composable Substreams modules for emerging standards (e.g. ERC-4626 vault flows) also count.

Examples:

A cross-protocol analytics dashboard comparing TVL/revenue across ten lending markets with one Lending/CDP standard-schema query
A DEX revenue comparator running one query pattern across every AMM on the DEX AMM standard
A layered MCP comparing lending, DEX, and derivatives markets side by side
A pipeline composing reusable Substreams packages (.spkg) into a new sink (Postgres, ClickHouse, Kafka, files)
A new composable Substreams module for an emerging standard (e.g. ERC-4626)
A new Standardized Subgraph for a protocol category that lacks one

Judging criteria: Leverage of composability/standards (35%) · Breadth (20%) · Technical execution (20%) · Usefulness (15%) · Demo & clarity (10%)

Qualification Requirements

Either compose two or more of The Graph's products, or build meaningfully on a standardized schema (e.g. Messari Standardized Subgraphs).
Consume live data from a Graph provider. Mocked or static data does not qualify.
Simply querying one Subgraph with no composition or standardization does not qualify.
Authoring/extending a Standardized Subgraph, or contributing a reusable composable Substreams module, is in scope.
Make the standards leverage clear — show what became easier because of a shared schema or composed product.
Submit a public repository and a 2–4 minute demo video.
