A proof-of-funds letter for crypto money: what it must contain to be accepted
A proof-of-funds letter for crypto money is a signed confirmation — from a bank, a regulated exchange or a licensed OTC desk — that a named person or company held or received a stated amount on a specific date. It differs from a source-of-funds file, which explains where the money came from. Banks, developers and visa offices often ask for both.
KEY FACTS
| What it confirms | A specific balance or a completed transaction, at one point in time |
|---|---|
| Typical issuers | Bank, regulated exchange, or VARA-licensed OTC desk |
| Who commonly asks for it | UAE banks, real-estate developers, immigration and visa offices |
| Not a substitute for | A source-of-funds file covering the money's origin |
| Single UAE-wide format | None — each recipient sets its own requirements |

What is a proof-of-funds letter for crypto money?
A proof-of-funds letter for crypto money is a short, signed document from a bank, a regulated exchange or a licensed OTC desk, confirming a named client held, received or transferred a stated amount on a specific date. It sits next to a full source-of-funds file, which explains where that money came from, not in place of it. The letter is a snapshot: one figure, one date, one issuer.
Recipients handling large crypto-linked transactions in the UAE typically want both documents together: the letter to confirm the money exists, and the file to confirm where it came from.
How does a proof-of-funds letter differ from a source-of-funds declaration?
A proof-of-funds letter for crypto money differs from a source-of-funds declaration in scope and timing: the letter is a point-in-time confirmation of a balance or a completed transfer, while the declaration is a narrative document set covering where the funds originated. A letter can often be produced within a day of the trade it confirms. A source-of-funds file usually takes longer to assemble.
The two serve different moments. A proof-of-funds letter usually accompanies one transaction, while a source-of-funds declaration supports an ongoing account relationship. Neither replaces the other when a reviewer asks for both.
What must a proof-of-funds letter contain to be accepted?
A proof-of-funds letter accepted by a UAE bank, developer or visa office usually contains the seven elements listed below. Missing any one of them is a standard reason a letter gets sent back for revision.
| Element | Why it matters | Common mistake |
|---|---|---|
| Issuer name and licence status | Shows a regulated entity stands behind the letter | Letter from an unlicensed platform or a personal export |
| Date of issue | Confirms the letter is current, not stale | No date, or a date months before it is used |
| Client's full legal name | Ties the letter to the account holder's ID | Name mismatch against passport or trade licence |
| Amount and currency | Gives the reviewer one concrete figure | A vague range instead of an exact amount |
| Balance or transaction date | Shows the exact point in time referenced | Letter silent on when the figure applied |
| Description of the funds' movement | Bridges the crypto leg to the fiat amount | No mention of the wallet-to-bank route at all |
| Contact for verification | Lets the recipient confirm the letter is genuine | No phone or email to call back on |
A letter naming the issuer, one figure, one date and the crypto-to-fiat route clears review far more often than a longer letter missing one of these points.
Who can issue a proof-of-funds letter for crypto funds?
A proof-of-funds letter for crypto funds is issued by a UAE bank, a regulated virtual-asset exchange, or a VARA-licensed OTC desk — never by the account holder describing their own wallet. Before requesting one, confirm the issuer's licence status with our checklist for verifying an OTC desk.
A licensed desk that settles a USDT-to-AED trade to your own-name bank account can issue a letter confirming that specific trade: amount, date and settlement account. That letter documents a completed transaction; it does not guarantee that a bank or developer will accept it, since acceptance is always the recipient's own decision. IWGT's own licence details sit in our licence section for anyone who wants to verify us first.
Requesting a letter is simplest right after a completed trade: complete the desk's onboarding checklist before you trade, then tell the desk who the letter is for, since a bank, a developer and a visa office often expect different wording.
Who accepts a proof-of-funds letter?
Three types of recipients commonly ask for a proof-of-funds letter tied to crypto money: UAE banks reviewing an account or a large inflow, real-estate developers ahead of a property reservation, and visa offices assessing financial means. None is bound to a single UAE-wide template.
Banks reviewing crypto-linked inflows want the most detail on the crypto-to-fiat leg, since that is the part they cannot see directly — our guide to how UAE banks treat crypto-linked inflows covers what triggers a closer look. Developers and visa offices usually accept a shorter letter.
Why do banks and developers reject proof-of-funds letters for crypto?
Proof-of-funds letters for crypto money get rejected for a short list of reasons: a name that does not match the passport, a letter dated too far in the past, an unverifiable issuer, and no explanation of how crypto became the fiat amount stated. A vague figure — "sufficient funds" — fails almost every time.
A rejected letter does not always mean the funds are suspect; often it was written for the wrong audience. Our guide on how to avoid a UAE bank account freeze covers the wider pattern: documentation gaps, not size, trigger most holds.
What is the bottom line on a crypto proof-of-funds letter?
A proof-of-funds letter for crypto money works when it names a real, verifiable issuer, states one amount on one date, and explains in a sentence how the crypto became the fiat figure shown. No single UAE-wide template makes a letter automatically acceptable, since each bank, developer or visa office runs its own review. Keep the underlying source-of-funds records ready too, in case the recipient asks for both.
FAQ
Is a proof-of-funds letter legally required to sell crypto in the UAE?
No single law makes a proof-of-funds letter mandatory for every crypto sale. Banks, developers and visa offices request one at their own discretion, usually alongside identity checks, when the transaction needs extra confirmation.
Can a licensed OTC desk write a proof-of-funds letter for me?
A VARA-licensed OTC desk can issue a letter confirming a trade it settled: the amount, date and settlement account. It cannot promise that a recipient will accept that letter, since each one decides on its own.
How long is a proof-of-funds letter valid?
Most recipients treat a proof-of-funds letter as current only for a short window after issue, and the exact period is set by the recipient, not by a fixed rule. Ask the recipient directly and request the letter close to when you will use it.
Does a proof-of-funds letter replace enhanced due diligence checks?
No. A proof-of-funds letter does not replace a bank's or desk's own closer review of large or unusual transactions; it is one document among several a reviewer may request.
Who should sign a proof-of-funds letter?
The letter should be signed or stamped by an authorised officer of the issuing bank, exchange or OTC desk, on the issuer's letterhead, with contact details a recipient can use to verify it. A letter signed only by the account holder about their own funds is a self-declaration, not proof of funds.
