Depends on the crypto they choose and all the other zero day exploits in their code. They'll likely use "bank grade" security, one notch up from the "military grade" junk they foist on the public. Only a question of which actors can break it and what they decide to do with their exploit.
The tech will be similar, and just get ported out via smart contracts. And I assure you they will get hacked to pieces at some point and fail.
