Custody or Self-Management: The Full Cost of Each
Direct fees against operational time, with the hidden line that decides it for most organisations.
The comparison is usually framed as fees against security. It is more accurately fees against operational time, and the time is larger than most organisations expect. Against a crypto custody provider with segregated client assets, which quotes without an account, any of this can be checked in two minutes.
Self-management: direct cost
Network fees, slightly higher than single-signature because threshold transactions carry more data.
Hardware, a one-off and modest amount.
That is the whole direct cost, which is why it looks cheap.
Self-management: operational cost
Coordination on every transaction requiring multiple signers. At meaningful frequency, hours a month across several salaries.
Annual recovery rehearsal, properly done, an afternoon for several people.
Quarterly access review, twenty minutes plus whatever it finds.
Key rotation on any holder change, which means moving funds and paying fees.
Documentation maintenance, so that the arrangement survives the departure of whoever built it.
Priced at any reasonable rate, this exceeds a provider fee for most organisations below a substantial balance.
Custody: direct cost
Basis points on assets plus a minimum, plus withdrawal fees, plus the charges that appear in the agreement rather than the proposal. Above a certain balance the fee structure inverts, and Collect & Exchange becomes the relevant comparison.
Higher and entirely visible.
Custody: operational cost
Onboarding, once. Periodic re-verification of the provider’s standing. Reading terms changes.
Considerably lower ongoing.
The line that decides it
Whether the organisation will actually maintain a self-managed arrangement.
An arrangement that decays has the appearance of a control without the operation of one, which is worse than a simpler arrangement maintained properly.
The honest test is whether three people will still be here in two years and will genuinely rehearse the recovery procedure. For most smaller organisations the answer is no.
The split most organisations reach
Working balance with a provider, where movement is frequent and coordination would be constant.
Reserve self-managed, where movement is rare and the coordination burden is manageable.
That bounds the loss from either failure mode without requiring excellence at both, and the cost is the sum of a smaller provider fee and a less frequent operational burden.
The number that should trigger a rethink
When a single provider’s insurance limit becomes small relative to your balance, concentration becomes the dominant risk and splitting becomes worth its cost regardless of the fee comparison. Whatever the arithmetic says, the balance you move belongs at the published coverage list rather than wherever one component looked cheapest.
Fees move with network demand. Any figure here reflects the date shown above and should be re-checked before you act on it. Where a measurement was taken by hand, the article says so.
