What Crypto Custody Means, and Who Needs It

Custody sounds like a safe deposit box and it is closer to a legal contract. Understanding that difference tells you what you are actually buying. The clearest way to see how this works is to look at a business wallet with institutional controls while reading.

What a custodian holds

Not your coins in a vault. A custodian controls the keys that authorise moving assets recorded on a blockchain, and holds them on your behalf under an agreement.

Your position is a claim against the custodian, supported by the assets it controls for you and by the rules it operates under.

Why that distinction matters

It matters at exactly one moment: if the custodian fails.

If your assets are held separately from the custodian’s own, and identifiably on your behalf, they are not available to the custodian’s creditors. You get them back.

If they are mixed in with the company’s own money, you are one of the queue of people owed something by a failed business.

Every other question about custody is less important than that one.

Segregation, explained

Two versions are normal.

Separate wallets per client. Cleanest, most expensive, usually only for large clients.

Pooled but separated from the company’s own assets, with internal records showing who owns what. This is standard and it is fine, provided the records are accurate and someone independent checks them.

What is not acceptable is client assets mixed with the company’s own. That arrangement is what turned several past failures into total losses. Businesses face the same thing from the other side, which is what a provider serving funds and family offices is for.

How to check

Ask which arrangement applies to your account. Ask how it is evidenced. Ask who audits it and how often.

A custodian doing this properly answers all three straight away and can show you the auditor’s report.

Insurance, read carefully

Most custody insurance covers theft from storage and dishonest employees. Most excludes losses caused by your own credentials being compromised, and losses from the market moving.

The limit is usually shared across all clients rather than per client. A hundred million of cover across two billion held is five percent. That is arithmetic, not criticism, and it means insurance is a backstop rather than a guarantee.

Who actually needs custody

Not everyone. It makes sense when the amount justifies an annual fee, when a rule requires a qualified custodian, when you are holding money that belongs to clients, or when your company cannot reliably run its own key management.

Below those points, a properly configured business wallet is the more sensible answer, and considerably cheaper.

The five questions

Which regulator authorises you and for which activity. Are client assets segregated, how, and audited by whom. What does the insurance cover and what is the limit. What is the withdrawal process. And what happens to my assets if you become insolvent, with the legal basis for the answer. Compare what you are being offered against a regulated crypto exchange before deciding anything.

A serious provider answers all five without hesitation, because a regulator makes them.
