Not a lot of info on their site about their Trident custody management requirements. Do you use them and have additional info? It would be surprising that they would insure bitcoin without having custody and controlling withdrawls.

So it’s collaborative custody via multisig like casa or unchained but it’s a decaying multisig that transitions into full self custody if you choose not to renew your insurance policy.
I found this from a link on one of your previous posts and now it makes sense within the context of an insurance policy. As I suspected they are a co-signer on withdrawls but don’t have full custody.
Trident Vault goes beyond traditional collaborative custody products built on legacy multisig by utilizing miniscript, offering two key advantages:
Time-locked recovery paths: This feature allows Bitcoin to be recovered using different combinations of keys over time.
Multisig of multisigs: This enables AnchorWatch to be a required signer on transactions while you're insured, ensuring that we can never unilaterally control a customer's Bitcoin.
