Research summary
Our research assessment is adverse. Polygon’s native PoS bridge is core infrastructure, not a source of portfolio yield, and every bridged claim depends on Polygon validator checkpoints and upgradeable bridge contracts. We separately rejected the Polygon chain because a Security Council can carry out an immediate emergency upgrade, with no enforceable user exit window before it acts. A $2.57B accounting balance does not outweigh that same control fact at the bridge layer.
Observable review triggers
- Every regular and emergency bridge upgrade becomes subject to an enforceable on-chain delay of at least 7 days
- A permissionless exit proof remains usable during validator or checkpoint failure and completes a proposed-size test
- Polygon's chain verdict changes to approved or approved-with-limits without an active bridge-control review trigger
