| ### Covered pausables and their pausers | ||
|
|
||
| Each pausable contract below is proposed to be covered by the CircuitBreaker, with a designated pauser authorized to trigger a pause. Pauser assignments are pending DAO approval ([LIP-34](https://github.com/lidofinance/lido-improvement-proposals/blob/develop/LIPS/lip-34.md)); until then, the existing [GateSeals](#dao-contracts) remain the active emergency-pause mechanism. The proposed pausers are the same multisigs that currently operate the GateSeals: the **CircuitBreaker Committee** (listed as [GateSeal Committee](#emergency-brakes-multisigs) until the migration completes) for core protocol pausables, and the **CSM Committee** (listed as [Community Staking Module Committee](#committees)) for CSM pausables. | ||

I suggest marking GateSeals on this page as [proposed to remove] and include a hyperlink to research forum CircuitBreaker forum post
and rename GateSeal commitee to CircuitBreaker committee as [proposed] as well
