These workers features are actually accompanied by a proper purge of earlier messages.

How the SEC’s withdrawal is reshaping “management” in crypto asset custody

The FAQ doesn’t say {that a} broker-dealer should have personal keys, however 15c3-3(c) management is tied to securing and directing the motion of buyer securities at a acknowledged management location.

For on-chain devices, this usually comes right down to who can signal or power signing via the save stack.

Every choice balances administrative burden, incident response design, and examiner consolation.

The December 17 renewal additionally retains a line clear for retail-focused companies: unsecured cryptocurrencies held at a broker-dealer are excluded from rule 15c3-3(b).

Corporations nonetheless want clear disclosure about which protections apply and which don’t.

Commissioner Hester Peirce framed the workers’s FAQs as incremental, whereas noting how the steering can scale back friction for market contributors attempting to suit in-chain actions into current rule units.
