What type/models of hardware wallets would exchanges use?

Some have like 100k bitcoins in hardware wallets. How do they keep the qctual wallet from being compromized. They surely cannt let anyone even the owners tranfer funds outside from it or even hold it Grin

Thats open to criminals chasing people with access to those wallets even if the employees were honest they are still under risk if they have sole access. So what type of hardware wallets would they use?

I see ledger has a wallet that can have multi seed access and transaction size restrictions but thats something new, surely there was a solution before ledegers one.

IMO, starshing 100k bitcoin in a single hardware is a totally bad idea, to be on a safer side,ill be glad to advise any exchange CEO to spread out their crypto asset in multiple hardware wallets with varying security measures so that in a worst case senario the digital asset will not all be tampered all at once via a single point of entry. and also, the concept of a once-per-quarter check up just like how Darb is doing it right now will help in cutting down the level of such occurrence.

I don't think that it is a bad idea as long as the wallet itself is reliable and popular enough to trust with such a large amount of funds. Diversifying does not always imply that your funds will be safe since it all comes down to the wallet itself at the end of the day.

Trezor would be my preferred wallet in this case. HSM is a good alternative.
