Data Providers

If you want to access aptos blockchain data but don’t need it in real-time. We have a few options that will let you access this data using SQL or UIs for building dashboards. This type of data is often used for analytics since it allows for aggregations.

Review of data endpoints

Hitting the full node directly will give the latest data (will be missing historical unless it’s an archival full node) using REST API

Indexer layer on top of this will provide a GRPC transaction stream

On top of this transaction stream, we’ve built out some product logic tables that can be queried through GraphQL

Since the logic to parse out transaction is public, some vendors have implemented similar parsing logic to create a subset of tables and made them available to query.

SQL Tables

Indexer defines several processors that create different database tables.

Core tables

These are parsed directly from node API response, one option is to split it out into the following tables:

  • Blocks - version, block height, epoch, timestamp
  • Transactions - version, sender, entry function, gas
  • Signatures - signature types, signer, fee payer address
  • Events - type and data for events

We store data as table items, resources or modules

  • (write set) changes - change index, change type, resource address
  • Table items - table key, table handle, key (content and type), value (content and type)
  • (move) resources - resource address, resource type, data
  • (move) modules - bytecode for deployed modules

Vendors of off-chain data

Most of our data vendors only provide core datasets. A subset of vendors is listed below

Google bigquery public dataset

Provides data through google public data

bq_sql

We also have sample analytics queries using the above resources

Dune

We have a dashboard here: https://dune.com/aptos/aptos-chain-metrics-overview

Flipside

Another dashboard vendor, signatures in core tables were merged into fact_transactions They also have a few more convenience tables (defi, nft, price), table list

Sentio

They have a guide here: https://docs.sentio.xyz/docs/aptos Data is found in data source -> external project -> sentio/aptos-overview

Space and Time

Data can be found here: https://app.spaceandtime.ai/data-sets?selectedChain=aptos They also have some non-core tables (Token, Staking, etc)

Other vendors

We also have some partners who target more enterprise use cases
