New Data Services Coming to The Graph

Substreams enables developers to write Rust functions that transform blockchain data and stream the output to multiple destinations simultaneously. **Key capabilities:** - Stream processed data to SQL databases - Send to PubSub systems - Deliver directly to applications or trading terminals The tool uses a single pipeline architecture that can output to multiple endpoints, eliminating the need for separate data processing workflows. Substreams modules are written in Rust and compiled to WebAssembly (WASM) for performance and safety benefits.

**The Graph is integrating AI agent infrastructure in 2026**, making blockchain data accessible to autonomous systems. **Key features coming to Subgraphs:** - **x402-compliant payment gateways** for micropayments without gas fee bottlenecks - **MCP integration** with Claude, Cursor, and ChatGPT - **Agent-to-Agent (A2A) protocols** for machine communication - **Natural language blockchain queries** instead of complex GraphQL This builds on The Graph's existing agent economy infrastructure: - ERC-8004 Subgraphs for verifiable agent identity across 8 chains - GraphTally micropayment system enabling fractional payments - Real-time data access for autonomous decision-making **The technical challenge solved:** Traditional blockchain queries require gas fees that exceed query costs (e.g., $0.05 gas for a $0.0001 query). GraphTally's cryptographically signed vouchers batch settlements, making thousands of queries per minute economically viable. **Result:** AI agents can now verify identity, pay for data autonomously, and query blockchain information in plain English—transforming The Graph from an indexing protocol into agent-native data infrastructure.

The Graph's open-source Subgraph framework demonstrates why shared standards outperform proprietary solutions in blockchain development. **The Problem** - Each protocol team previously built custom data extraction logic - Result: incompatible formats, duplicated work, wasted resources **The Solution** - The Graph open-sourced Subgraphs as a shared indexing standard - 75,000+ developers now use the same data transformation patterns - Collective debugging and optimization compound across the entire ecosystem **Why This Matters** Proprietary solutions scale linearly with one vendor's resources. Open standards scale with every developer who contributes improvements. When data structures are shared across chains and protocols, teams stop rebuilding infrastructure and focus on building applications that matter. Open standards aren't flashy, but they're how technology actually advances.

**The Challenge of Blockchain Data Access** Blockchains excel at consensus and security, but struggle with fast data retrieval. As transaction throughput increases and more chains emerge, a critical gap widens between data existing onchain and applications being able to use it effectively. **Key Issues:** - High-throughput chains like Solana generate data faster than traditional indexing systems can process - Cross-chain applications require unified access patterns across incompatible data structures - Raw blockchain logs must be transformed into structured, queryable formats at application speed **The Core Problem** The fundamental scalability challenge isn't just about processing more transactions—it's about making that data accessible and usable for applications in real-time. Traditional indexing methods can't keep pace with modern blockchain throughput.

**The Graph Foundation's Product Marketing Lead Brandon Kramer presented at the Solana Mini-Summit during ETHDenver**, discussing the protocol's data indexing tools. **Key topics covered:** - Substreams for blockchain data processing - Subgraphs for organizing blockchain information - Token API functionality The presentation highlighted The Graph's cross-chain capabilities, demonstrating how its indexing protocol serves both Ethereum and Solana ecosystems. The session took place at an unofficial Solana event running parallel to the main ETHDenver conference.
