An asset appears in an account balance. The natural assumption is that it belongs to the account holder, in the same way a share held through a broker does.
For digital assets that assumption depends entirely on how the holding is arranged. The same balance can represent direct control of an asset, a claim against a firm that holds it on your behalf, or a claim against a firm that holds it alongside everyone else’s without distinguishing whose is whose.
Those three situations look identical on a screen and behave very differently if the firm fails. Regulators in Europe and Switzerland have now written rules that specify which is which, which makes this checkable rather than a matter of trust.
Four Ways to Hold the Same Asset
The question whats cryptocurrency usually gets answered at the protocol level, describing how a network records ownership.
The more practical question is what a specific holding represents legally. There are four common arrangements:
Each carries a different risk. Direct control removes counterparty risk and transfers the entire operational burden to the holder. The other three remove that burden and introduce a firm whose financial condition now matters.
What Segregation Actually Requires
The European framework sets out what a custodial arrangement must involve, and the requirements will look familiar to anyone who has read about traditional client asset rules.
A legal summary of the regime notes that authorised custody providers must ensure client assets are legally and operationally segregated from the assets of the firm to insulate clients insofar as possible from the insolvency risk of the custodian, that a register of positions must show clients’ entitlements, that a written custody policy must set out internal rules to prevent loss of assets or the keys controlling them, and that client statements must be provided periodically or on request.
Two words carry most of the weight. Legal segregation means creditors of the firm have no claim on client assets. Operational segregation means the assets are actually held separately in practice, including on the ledger itself, rather than merely recorded separately in an internal database.
Three Arrangements, Three Outcomes
The Swiss regulator has set out the distinctions more explicitly than most, and the framework is useful regardless of jurisdiction because it describes arrangements rather than local law.
Guidance issued in 2026 distinguishes three cases. Where assets are held separately for each client with an obligation to hold them in readiness at all times, segregation in bankruptcy is guaranteed and the assets are excluded from the bankruptcy estate. Where assets of multiple clients are held together but each client’s share is clearly recorded, with the same readiness obligation, segregation is also guaranteed. Where no such obligation exists or client shares are not clearly identifiable, no segregation occurs.
That third case is the one worth understanding. Assets pooled without identifiable client shares do not sit outside the firm’s estate, which means the holder becomes an unsecured creditor rather than an owner.
The same guidance makes a further point that applies to any cross-border arrangement: the fact that a foreign custodian is supervised does not by itself guarantee bankruptcy protection, because the relevant question is whether that jurisdiction recognises the client’s property rights.
What to Establish Before Choosing
The information is disclosable, so the work is asking rather than assuming:
The fifth point is frequently misread. Custody insurance generally covers loss of assets through theft or operational incident. It is not protection against the provider becoming insolvent, and the two get conflated in marketing material.
What Custody Doesn’t Protect Against
Strong custody arrangements address one risk precisely and leave others untouched.
They do not address price risk, which remains whatever the asset does. They do not address the holder’s own operational errors, including sending assets to a wrong address, which is generally irreversible. And they do not make an unsuitable position suitable.
What they do determine is whether a holder is an owner or a creditor if the firm holding their assets stops operating. That distinction has been decided the hard way in this market more than once, and it is now written into regulation clearly enough that anyone can check which side of it they are on.
