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:

DatasetDescription
BlocksMetadata for each block on the chain including hashes, transaction count, difficulty, and gas used.
LogsRaw logs for events emitted from contracts. Contains the contract address, data, topics, and metadata for blocks and transactions.
Enriched TransactionsTransaction data including input, value, from and to address, and metadata for the block, gas, and receipts.
TracesTraces of all function calls made on the chain including metadata for block, trace, transaction, and gas.

Stellar

DatasetDescription
AssetsContains information about all assets issued on the Stellar network, including details like asset codes, issuers, and related metadata.
Contract EventsRecords events related to smart contract execution on the Stellar network, detailing the interactions and state changes within contracts.
EffectsCaptures the effects of various operations on the Stellar ledger, such as changes in balances, creation of accounts, and other state modifications.
LedgersProvides a comprehensive record of all ledger entries, summarizing the state of the blockchain at each ledger close, including transaction sets and ledger headers.

Sui

DatasetDescription

TransactionsTransaction data including effects, events, senders, recipients, balance and object changes, and other metadata.

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:

DatasetDescription
ERC_20Every transfer event for all fungible tokens.
ERC_721Every transfer event for all non-fungible tokens.
ERC_1155Every transfer event for all ERC-1155 tokens.

Polymarket datasets

DatasetDescription
Global Open InterestKeeps track of global open interest.
Market Open InterestKeeps track of open interest for each market.
Order FilledThis 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 MatchedThis 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 BalancesThis event keeps track of all user outcome token positions.
User PositionsKeeps 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.
