VERDICT

Should I use Thirdweb?

Infrastructure for AI Agents - thirdweb.com

Depends. Buy if you're building an onchain app and want wallets, contracts, RPC, and auth bundled in one platform. Skip it if your product has no blockchain component, or if a multi-incident security record is disqualifying for you.

Confidence

Medium. Based on 30+ public sources; review samples are small, so satisfaction signals are weak.
