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.

​

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:

Move Calls	Move calls are a function invocation within a Move smart contract, executed by the Movement VM to perform specific operations or state transitions on the blockchain.
Transactions	A transaction in the Movement VM is a signed instruction executed by the Move smart contract to modify the blockchain’s state, such as transferring assets or invoking contract functions.

​

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.

Additional chains, including roll-ups, can be indexed on demand. Contact us at sales@goldsky.com to learn more.

Backfill vs Fast Scan

Goldsky allows you either backfill the entire datasets or alternatively pre-filter the data based on specific attributes. This allows for an optimal cost and time efficient streaming experience based on your specific use case. For more information on how to enable each streaming mode in your pipelines visit our reference documentation.
