Write Streams Filters in Go. Or Don't Write Them at All
Write Streams Filters in Go. Or Don't Write Them at All
August 10, 2026 — 3 min read
Quicknode Streams filters can now be written in Go, and Quicknode's AI Filter Agent turns a plain-language prompt into an optimized filter. Both are live in the filter editor today.
Faster filters, especially on fast chains
Go filters run in-process, 30% faster, especially on high-throughput chains like Solana and Robinhood.
The gain comes from the runtime. Running a filter inside an isolated VM adds parsing and execution overhead to every invocation. Go filters skip the VM, so that overhead is gone, and at high block rates the saving compounds. The heavier the filter, the bigger the difference. The gap is widest on compute-intensive logic and large block payloads.
Filter your stream without writing code
Streams filters are getting easier to configure and deploy, based on user feedback. Quicknode's AI Filter Agent writes the filter for you.
Open the filter editor and describe what you want in plain language:
"filter all transactions and token transfers that involve addresses in my 'wallets' list"
The agent returns an optimized, annotated filter using the correct fields for your selected network and dataset. It has context on the filter API, per-chain payload schemas, Key-Value Store capabilities and best practices, and a library of real-world filter templates.
