What is Subsquid (SQD)?

Deep Dive

1. Purpose & Value Proposition

Subsquid was created to solve the scalability and rigidity problems of earlier blockchain indexing frameworks. It provides developers with performant, permissionless access to structured on-chain data, which is essential for building decentralized applications (dApps), analytics platforms, and AI agents. By decentralizing data access, it aims to be a neutral foundation for a more open internet, serving as an alternative to centralized API providers.

2. Technology & Architecture

The network is built on a modular architecture secured by zero-knowledge (ZK) proofs, which verify data correctness without revealing underlying information. This design enables high scalability and fast querying. Subsquid supports a wide range of blockchains—including Ethereum, Solana, and Polkadot—through products like its Squid SDK and SQD Cloud APIs, making it a versatile data layer for the Web3 stack.

3. Tokenomics & Network Evolution

The SQD token is central to network operations. It is used to incentivize node operators, for governance, and to manage query rate limits. A key innovation is the Revenue Pools model launched in December 2025 (Decrypt), where token holders can lock SQD to support network capacity and earn a share of fees paid by enterprise customers like Deutsche Telekom. This ties token utility directly to real-world demand. Furthermore, the project's acquisition by Rezolve AI in October 2025 positions it as the data layer for an integrated AI-commerce ecosystem.

Conclusion

Subsquid is fundamentally a decentralized data utility, evolving from a developer tool into an institutional-grade infrastructure network with its tokenomics aligned to sustainable, demand-driven growth. How will its integration within broader AI and commerce stacks shape the future of on-chain data accessibility?
