Mirror

Stream blockchain data

Fresh data, from chain to table.
Always a heartbeat ahead.

Start streaming

Sub-second latency at scale

Mirror is fast enough to power orders on prediction markets and trading platforms.

For modern crypto teams

Connect to Postgres for apps or Clickhouse for analytics. Add built-in filtering and decoding.

Universal support

Source your database from anywhere - subgraphs, transactions, or pre-made datasets.

Developer Experience

Developer-first workflows for the whole team

Even if you're not a developer, there's an option for every type of builder.

CLI

Do all things pipelines from your terminal. Less clicking, more shipping. Our CTO lives by it.

~/terminal

>goldsky pipeline create my-pipeline

Pipeline created successfully

>goldsky pipeline resize --size large

Resized to large (4 cores, 16GB RAM)

YAML Config

Pipeline configs you can version, review, and automate. Plays nice with your Git workflows and CI/CD pipelines.

TypeScript transforms

Call external APIs. Pull in libraries. Write complex logic to make your data do tricks.

Features

Raw blocks to clean tables

Start with a fresh dataset or slot Mirror into your existing data stack. Source, transform, and stream data to power whatever you're building.

Sources

Live-stream blockchain data from 140+ supported chains.

Transforms

Customize your dataset and schema through with SQL or TypeScript. Use HTTP handlers for external data enrichment.

Self-healing

Handles reorgs and backups automatically. One less thing to worry about at 2 AM.

Elastic compute

Scale up for fast backfilling and scale down once you’re caught up to optimize capacity.

Using Subgraphs?

Keep them. Use your existing subgraphs as a data source to stream to any destination.

Destinations

Liam Kovatch

Head of Engineering, Polymarket

Polymarket has a lot of customer data living offchain, and needed a way to marry that to trade activity. Mirror was a huge unlock for us, letting us write onchain data to our Postgres database instantly to build more complex APIs.
