Question 1

How does Subsquid work?

Accepted Answer

Subsquid utilizes a decentralized peer-to-peer data lake and modular Squid SDK. This powerful technology helps individual developers build highly customizable real-time indexers and GraphQL APIs for their decentralized applications. Furthermore, businesses can efficiently query complex multi-chain analytics across 190+ networks without managing their own dedicated blockchain node infrastructure.

Question 2

Is Subsquid a secure platform?

Accepted Answer

Security is strongly guaranteed by a trustless decentralized coprocessor architecture where validators process and serve verifiable query results directly. The platform underwent a comprehensive ChainSecurity smart contract audit discovering zero critical or high severity vulnerabilities across the entire codebase. Since no catastrophic exploits occurred, developers can safely build production-grade applications relying on this decentralized data infrastructure.

Question 3

How to use Subsquid?

Accepted Answer

First, developers install the Squid SDK and configure their preferred EVM or Substrate blockchain data source. Next, they define custom data processors, filters, and transformation logic tailored to their application requirements. Finally, they deploy the completed indexer to the decentralized network and access structured data through an integrated GraphQL API endpoint.

Question 4

What services does Subsquid offer?

Accepted Answer

The platform offers decentralized blockchain data indexing, real-time multi-chain querying, and a modular SDK for production decentralized application development. Developers can seamlessly retrieve token transfers, NFT metadata, smart contract events, and on-chain analytics across all major supported networks simultaneously. Additionally, individuals can stake native SQD tokens to earn network rewards while helping power the decentralized data infrastructure.
