What is custody in crypto? Keys, custodians and segregation
Custody in crypto is the holding of the private keys that control your coins — whoever holds the keys controls the assets. You can keep custody yourself (self-custody) or hand it to a licensed custodian, and the choice decides who can move, freeze or lose your USDT.
KEY FACTS
| Term | Custody — control of the private keys |
|---|---|
| Self-custody | You hold the keys (hardware or software wallet) |
| Custodial | A licensed third party holds the keys for you |
| Dubai regulator | VARA (outside the DIFC), licence VL/24/12/002 |
| IWGT flow | From ~100,000 USDT; your keys until settlement |

Self-custody vs custodial
You hold the keys in a hardware or software wallet, or a third party holds them for you. Self-custody removes counterparty risk but makes a lost seed phrase a permanent loss; a custodian adds counterparty risk (failure, freeze or hack) in exchange for professional controls.
How does crypto custody work in the UAE?
In Dubai outside the DIFC, VARA licenses custodians under a dedicated custody rulebook; the DIFC and Abu Dhabi's ADGM have their own regulators, the DFSA and the FSRA. VARA's rules require client assets to be segregated from the custodian's own, so they should not be available to the firm's creditors if it fails. Check licence numbers in VARA's public register; ours is in the licence section.
Why it matters when selling USDT in the UAE
At an OTC desk custody changes hands only for the settlement window: you keep your keys until you accept a written quote, then transfer the agreed amount, and the desk wires AED to your own account by UAEFTS the same business day. Approval happens before the trade (see onboarding), so paperwork does not stretch the window. The end-to-end route is in cashing out crypto in Dubai legally.
Illustrative example
500,000 USDT held on a hardware wallet, the route in cashing out from a hardware wallet: the desk has no access before you send; at a 0.15% spread and the 3.6725 peg, AED 1,836,250 gross becomes AED 1,833,496 by UAEFTS the same business day, as of September 2026. Before trusting any counterparty, ask in writing whether client assets are segregated or pooled, which licence covers custody, how long from on-chain receipt to the wire, and what happens to client assets if the firm fails.
FAQ
Is self-custody safer than using a custodian?
Neither is automatically safer. Self-custody removes counterparty risk but makes a lost key or seed phrase a permanent loss. A licensed custodian adds counterparty risk but replaces key-loss risk with professional key management, insurance arrangements and segregation rules.
Does a VARA licence mean client assets are segregated?
For custody as a regulated activity, yes: VARA's rulebooks require client virtual assets to be held separately from the custodian's own assets. Check that the licence in VARA's public register actually covers custody before relying on this.
Do I give up custody of my USDT when I sell at an OTC desk?
Only during settlement. You keep your keys until you accept a written quote, then transfer the agreed amount to the desk; the desk wires AED to your own bank account the same business day, ending its custody of the coins.
What happens to my crypto if a custodian fails?
With proper segregation, client assets should not form part of the failed firm's estate and should be returned to clients. Without segregation, coins can be treated as the firm's property in insolvency — which is why segregation is the question to ask first.
