Data Sources
Direct indexing
With mirror pipelines, you can access to indexed on-chain data. Define them as a source and pipe them into any sink we support.
* The Arweave dataset includes bundled/L2 data.
Additional chains, including roll-ups, can be indexed on demand. Contact us at sales@goldsky.com to learn more.
Use-cases
- Mirror specific logs and traces from a set of contracts into a postgres database to build an API for your protocol
- ETL data into a data warehouse to run analytics
- Push the full blockchain into Kafka or S3 to build a datalake for ML
Supported Chains
EVM chains
For EVM chains we support the following 4 datasets:| Dataset | Description |
|---|---|
| Blocks | Metadata for each block on the chain including hashes, transaction count, difficulty, and gas used. |
| Logs | Raw logs for events emitted from contracts. Contains the contract address, data, topics, and metadata for blocks and transactions. |
| Enriched Transactions | Transaction data including input, value, from and to address, and metadata for the block, gas, and receipts. |
| Traces | Traces of all function calls made on the chain including metadata for block, trace, transaction, and gas. |
Fast Scan
Some datasets have support for Fast Scan which allows you to more quickly backfill filtered data. If a chain has partial support for Fast Scan, the dataset that doesn't support fast scan will have an asterisk* next to it.
Here's a breakdown of the EVM chains we support and their corresponding datasets:

Curated Datasets
Beyond onchain datasets, the Goldsky team continuosly curates and publishes derived datasets that serve a specific audience or use case. Here's the list:Token Transfers
You can expect every EVM chain to have the following datasets available:| Dataset | Description |
|---|---|
| ERC_20 | Every transfer event for all fungible tokens. |
| ERC_721 | Every transfer event for all non-fungible tokens. |
| ERC_1155 | Every transfer event for all ERC-1155 tokens. |
Polymarket datasets
| Dataset | Description |
|---|---|
| Global Open Interest | Keeps track of global open interest. |
| Market Open Interest | Keeps track of open interest for each market. |
| Order Filled | This event is emitted when a single Polymarket order is partially or completely filled. For example: a 50c YES buy for 100 YES matched against a 50c YES sell for 100 YES will emit 2 Orderi Filled events, from the perspective of the YES buy and of the YES sell. This is useful for granular tracking of trading activity and history. |
| Orders Matched | This event is emitted when a Polymarket taker order is matched against a set of Polymarket maker(limit) orders. For example: a 50c YES buy for 200 YES matched against 2 50c YES sells for 100 YES each will emit a single Orders Matched event. Orders Matched gives a more high level view of trading activity as it only tracks taker activity. |
| User Balances | This event keeps track of all user outcome token positions. |
| User Positions | Keeps track of outcome token positions along with pnl specific data including average price and realized pnl. |
