Squid SDK is a TypeScript ETL toolkit for building blockchain data indexers, supporting Ethereum-like chains, Substrate, and Solana, with data sourced from the SQD Network's decentralized data lake via its Portal API. It provides fast binary codecs, type-safe decoded data access, reorg handling, persistence to databases like PostgreSQL, and auto-generated GraphQL APIs.
Use cases
- index ethereum transactions and events into postgres
- build a graphql api for on-chain defi data
- track token transfers and swaps on solana
- replace the graph subgraph with a custom indexer
- stream blockchain blocks for analytics dashboards
- build a backend for a dapp that reads on-chain state
- index substrate chain events from polkadot
- feed on-chain data to ai agents or trading analytics
When to choose
- you need a code-first, type-safe indexer toolkit rather than a declarative indexing app
- you want high-throughput blockchain data streaming from SQD Network's Portal instead of slow RPC calls
- you need multi-chain support (EVM, Solana, Substrate) in one framework
- you want auto-generated GraphQL APIs over indexed data
When to avoid
- you only need occasional one-off RPC queries rather than full-chain indexing
- you prefer declarative subgraph-style indexing with minimal code (TheGraph or Ponder may fit better)
- your project is not in the TypeScript/Node.js ecosystem
- you don't want any dependency on SQD Network or Portal infrastructure
