Veilify screens funds at the door. A deposit is not credited when it is sent. It waits as pending until the gatekeeper has checked the depositing address.

What the gatekeeper can and cannot do

Retrospective taint recovery

Screening at the door can miss funds that are flagged later. For that case, every approved deposit carries a trace key chosen by the gatekeeper. See Trace Keys.

Robinhood Chain context

Robinhood Chain also screens at the sequencer level. The Veilify gatekeeper is a separate, protocol-level control. It applies to deposits into the pool, whatever the chain admits.
