StreamingFast April 2026 Update

Hey everyone — here’s a quick look at what we shipped in April across Substreams, Firehose, and our broader infrastructure, along with what’s currently in progress.

This month focused on improving performance, simplifying developer workflows, and laying the groundwork for more managed and hosted experiences.


What we shipped

Substreams Skills Improvements – Continued expanding Substreams Skills with a focus on reducing the barrier to entry. We’re pushing toward a more no-code-friendly experience — not just for writing Substreams, but eventually for running the full data stack end-to-end.

Base Reth is now Ready – Base Reth is now running smoothly on Base Sepolia, with all internal tests passing. We’ll be migrating Base mainnet to Reth soon, with no action required from users.

Substreams Index Speed Improvements – Delivered additional performance gains to Substreams indexing, improving throughput and overall efficiency across workloads.

Monad Extended Blocks - Binary is complete. Reprocessing of chain history underway, but endpoint is available - mainnet.monad.streamingfast.io


What’s in flight

Hosted Sinks via The Graph Market – Working toward enabling users to pay for fully hosted sinks directly through The Graph Market, making it easier to deploy and manage production-grade data pipelines without self-hosting or bringing your own database/storage

Hosted Stores via The Graph Market – Building the ability for users to bring their existing Substreams stores directly into hosted stores, enabling larger stores.

Squasher Improvements – Ongoing work on decoupling and improving the squashing process to increase flexibility and performance.

New Full Chain Integration (Streaming-First) – A new blockchain has signed on for a full integration, upgrading from an RPC Poller setup to a streaming-first architecture using Firehose and Substreams.
