@subsquid is insanely good, especially since the Firesquid release. Highly recommend using it for Paraverse ecosystem projects.

@subsquid is a great tool for developers for indexing blockchain data. Loved it.

Now with the integration of @subsquid, we will enable devs to access high-quality on-chain data & build state-of-the-art dApps.

@subsquid is the best indexer I've seen in web3 ecosystem 🤞.

Seriously, @subsquid  is such a breeze to work with, re-indexing in few minutes is just amazing and makes our lives so much better at @RmrkApp

@subsquid is in another level when it comes to indexing blockchains. Not only speed, it’s so developer friendly and flexible.

@subsquid is a great tool that helps us to deliver the best experience for tokenguard users.

@subsquid for the win.

Looking forward to @subsquid's aggregated Giant Squid API, should make things incredibly easy for the Saturn UI...

The team at @subsquid are amazing. I'm so glad to be working with them 🚀.

You guys are awesome, thanks for always offering to help us <3.

Thanks, @subsquid, for the value you provide. Looking forward to show the Loading time reduction in action.
