I Tried SubQuery – Here's What I Think

As someone working with blockchain data, I’m always on the lookout for tools that make indexing and querying more efficient. Recently, I decided to try SubQuery, a decentralized data indexing protocol designed for Web3, and I have to say – I’m impressed.

Getting started was straightforward. The documentation is clean, and the setup process for creating a new project felt familiar, especially if you've used GraphQL-based indexers before. SubQuery supports various networks (like Polkadot, Cosmos, and Avalanche), which makes it quite versatile.

One thing I really liked was how flexible the mapping logic is – it lets you write custom logic in TypeScript, which adds a lot of power to data transformations. Also, deploying to SubQuery’s hosted service was smooth and didn’t require much overhead.

That said, I did run into a few bumps. The learning curve can be steep if you're new to blockchain indexing, and debugging mappings sometimes lacks transparency. But overall, the experience felt solid and production-ready.

If you’re building a dApp and need fast, reliable access to on-chain data, SubQuery is definitely worth trying.
