Subsquid SDK is a TypeScript ETL toolkit for blockchain data, that currently supports

• Ethereum and everything Ethereum-like
• Substrate-based chains
• Solana.

Subsquid SDK stands apart from the competition by

• Being a toolkit (rather than an indexing app like TheGraph or Ponder)
• Fast binary data codecs and type-safe access to decoded data
• Native support for sourcing the data from Subsquid Network.

The latter is a key point, as Subsquid Network is a decentralized data lake and query engine, that allows to granularly select and stream subset of block data to lightweight clients while providing game changing performance over traditional RPC API.

The best way to get started is to install squid CLI and scaffold a squid project with sqd init.
