Summary
Hey all, I’m excited to share this month’s product update!
This month marked strong progress across Substreams, Firehose, and thegraph.market. On the core technology side, we continue to advance instrumentation for Reth, released new Foundational Stores (with time travel queries and sample modules like ERC-20 token metadata and SPL initialized accounts), and added NEAR testnet support. Substreams SQL Sink was further strengthened with packaging improvements and expanded type support, making it easier for developers to adopt in production.
On thegraph.market, we introduced organizational account management and continued work toward automatic billing, while also successfully onboarding additional indexer endpoints. Community adoption remains a priority: we open-sourced key JWT, session, and metering tooling, and hosted a Substreams workshop with Solana Superteam during Korea Blockchain Week.
Together, these milestones highlight our commitment to improving developer experience, scaling the ecosystem, and strengthening The Graph’s infrastructure for the next generation of builders.
Looking back
-
Foundational Stores – Introduced a new Substreams data type designed to store predefined data at a block-by-block level.
-
Sample Foundational Stores – Released example Foundational Stores: erc20-token-metadata and spl-initialized-account as the first two publicly accessible Foundational Stores.
-
Time Travel Queries – Foundational Stores now also support time travel queries, enabling developers to access and query past states of data streams.
-
-
Reth Instrumentation Testing – Advanced instrumentation work completed to support Flashblocks. Initial testing is done, block headers have been successfully extracted, and work has begun on revised reorg handling.
-
SQL Sink Packaging – The Substreams SQL Sink is now packaged directly within Substreams codegen, making it easier for developers to adopt and use.
-
SQL Sink Decimal & Int Support – SQL sink “from proto” now supports extended data types including Decimal128, Decimal256, Int128, UInt128, Int256, and UInt256.
-
SQL Sink Array Support – SQL sink “from proto” now also supports native array types.
-
JWT Metadata & Metering – Session, authentication, and metering plugins have been open-sourced within firehose-core to serve as indexer tooling for Substreams gateways.
-
thegraph.market Enhancements – Released organizational-level account management. Workspaces can now be created and shared among teams.
-
NEAR Testnet Support – Added full Substreams and Firehose support for the NEAR testnet.
-
Solana Performance – Investigated Solana Substreams performance benchmarks.
-
thegraph.market Billing – Building out automatic billing functionality within thegraph.market for usage-based monetization.
-
Solana Superteam Workshop – Hosted a developer workshop with Solana Superteam during Korea Blockchain Week.
-
Indexer Onboarding – Successfully onboarded a third indexer’s endpoints to thegraph.market, expanding provider coverage.
Looking ahead
For October, here are some of our goals to continue driving momentum within The Graph:
-
Foundational Stores & Market Announcement – Publish a public marketing announcement highlighting the launch of Foundational Stores and recent thegraph.market enhancements.
-
Solana Latency Improvements – Ship support for streaming processed blocks (in addition to confirmed), with a toggle for users to switch between modes, reducing data latency.
-
Performance Benchmarking – Deliver improved benchmarking on chains with sub-second block times, giving users clearer insights and multiple performance views.
-
Reth Instrumentation – Deploy Reth instrumentation into a testnet environment as part of advancing optimal Flashblocks support.
-
New Instrumentation – Begin investigating instrumentation of a new EVM client to expand Firehose/Substreams integration paths.
-
Historical Reprocessing – Research improvements to historical reprocessing with a focus on reducing WASM execution overhead.
-
Network Integration Scope – Continue defining the scope and roadmap for bringing Substreams natively onto The Graph Network.
-
Tier 1 Expansion – Support a Tier 1 user expanding their Substreams dependency from Solana to multiple EVM chains.
