VERDICT

Should I use Ankr?

Build on Web3 with a fast, reliable and distributed network of blockchain nodes. Earn with Liquid Staking and integrate it to power your app. - ankr.com

Depends. Buy for Web3 developers who need free or credit-based RPC across 70+ chains; start on the free tier before committing. Skip the liquid staking products if you can't stomach multiple past exploits, and compare Alchemy or QuickNode for production workloads.

Confidence

Medium. Based on 40+ public sources; several review and security snippets were truncated at the source.

Solid free multi-chain RPC for Web3 devs, but the staking side carries real exploit history. Compare Alchemy first.
