Common Data

Features

In order to improve developer understanding of feature coverage, we have collected the most common features offered by providers:

Feature	Sub-Feature	Description
Chain data		Raw data (blocks, transactions, logs, traces) in SQL-like format. Transactions and logs may optionally be decoded based on ABI
Balances	Native	Native token holdings of an address, real-time or snapshot. May include price annotations
	ERC20	ERC20 holdings of an address, real-time or snapshot. May include price annotations
	NFT	NFT (ERC721 or ERC1155) holdings of an address, real-time or snapshot
Transfers	Native	Native token transfers involving a particular address. May include price annotations
	ERC20	ERC20 transfers involving a particular address. May include price annotations
	NFT	NFT transfers involving a particular address
DEX trades		Normalized trade data across major DEXes
Market data		Market data for ERC20s

Balances are nontrivial because each ERC20 and NFT collection stores its balances in contract storage. Transfers are nontrivial because they frequently occur as subroutines. Annotating with prices and normalizing across DEXes add additional convenience.

Access models

• APl: Data lives on provider's servers; make queries via API
• Stream: Data is replicated to your environment

QuickNode

QuickNode Streams is a managed, push-based blockchain streaming service that provides guaranteed delivery of both live and sequential historical data. With QuickNode Streams, you can choose to receive raw or filtered data—such as specific contract events—pushed directly to your stream destination (webhook, S3, Postgres, Snowflake, or Functions).

• Guaranteed Delivery: Robust retry logic and guaranteed delivery ensures that you never miss critical events.
• Push-Based Streaming: Events are pushed to your destination, eliminating the need for manual polling.
• Live & Sequential Historical Data: Process new events as they occur, and seamlessly backfill older blocks in chronological order.
• Raw or Filtered Data: Define filtering conditions (e.g., specific contract addresses or event signatures) using JavaScript to reduce noise and receive only the data you care about.
• Managed Service: QuickNode handles all node infrastructure, allowing you to focus on building without worrying about uptime or scaling.

To get started, visit the documentation for detailed instructions on creating streams, setting filters, and choosing a delivery method. Or, check out the quickstart guide to deploy a simple webhook receiver and configure a stream in minutes.
