Polygon POS only has 100 validators and is being controlled by [5/9 multisigs](https://wiki.polygon.technology/docs/faq/commit-chain-multisigs/)
Optimism has not activated fraud-proofs and most other L2s have red warnings on [L2 Beat](https://l2beat.com/scaling/risk)
The choice is really ZkSync or StarkEx. On paper ZkSync may be the most secure since it’s ZKR and not validium. However, StarkEx already have billions of TVL and more battle-tested than ZkSync.
Is it a good idea to move a lot (like 90%) of my funds on L1 to StarkEx?
