Source of Funds Requests on Duel.com
Why Duel.com may ask where your crypto came from, what evidence works (exchange statements, on-chain history, bank records), how to present it, and what happens if you refuse.

Quick answer
Source of funds (SoF) checks feel invasive because they are meant to be. Anti-money-laundering rules require a licensed operator to understand where large sums came from, not just whose face is on the ID. Duel.com has no routine KYC, so an SoF request is rare — but when it arrives it almost always sits between you and a withdrawal, and it is the most demanding review the platform runs. This guide explains what is being asked, what evidence works for crypto, and how to respond so the case closes in one round.
Why Duel.com asks
Duel.com operates under an Anjouan gaming licence (ALSI-202411026-FI1), which carries AML obligations even though it is an offshore regime. The terms reserve the right to request verification before processing a withdrawal where there are AML concerns or unusually large transactions. SoF is that clause in action.
What typically prompts a source of funds request
- Large single transactions
- A deposit or withdrawal far above your account's history
- Cumulative volume
- Total turnover crossing an internal, unpublished threshold
- Pattern mismatch
- Deposit then immediate withdrawal with little play; funds from many wallets
- Risk flags
- VPN use, restricted-region logins, third-party or mixer-linked wallets
Duel.com does not publish the thresholds. Full context on every trigger is in when verification is requested.
SoF vs standard identity verification
| Aspect | Identity check (KYC) | Source of funds |
|---|---|---|
| Question answered | Who are you, how old, where do you live | Where did this money come from |
| Typical evidence | Photo ID, live selfie, sometimes address proof | Exchange records, on-chain history, bank statements, income proof |
| Run by | Checkin.com automated flow, then Duel.com staff if flagged | Duel.com compliance staff, usually by request-and-response |
| Typical duration | Minutes to a few days | Several days to 10+ days, often in rounds |
| How often on Duel.com | Uncommon (no routine KYC) | Rare — large or unusual volumes only |

What evidence works
The reviewer wants an unbroken, dated story from legitimate origin to your Duel.com deposit. The document set depends on where the money started.
| Feature | Origin | Evidence that usually satisfies |
|---|---|---|
| Bought crypto on an exchange | Most common | Exchange statement or trade history in your name, plus TXIDs from the exchange withdrawal to your wallet |
| Salary or self-employment | Fiat origin | Recent payslips or tax return, and the bank statement showing the transfer to the exchange |
| Savings | Accumulated | Bank statements showing the balance building over time |
| Asset sale (property, vehicle, business) | One-off sum | Sale contract or completion statement, plus the bank credit |
| Long-held or mined crypto | On-chain origin | Wallet history showing acquisition date, mining pool payout records, and a signed message or screenshot proving wallet control |
| Gambling winnings elsewhere | Third-party platform | Withdrawal history from that platform in your name, plus the TXIDs to your wallet |
| Gift or inheritance | Third-party transfer | Letter from the giver, probate or estate documents; sometimes the giver's own source of funds |
Building a crypto trail the reviewer can follow
Crypto is actually easier to evidence than cash, because every hop is public. The work is in presenting it clearly.
Step 1
Fiat origin
Bank statement showing salary, savings or sale proceeds
Step 2
Exchange purchase
Exchange statement in your name showing the buy
Step 3
Withdrawal to your wallet
TXID from exchange to your self-custody address
Step 4
Deposit to Duel.com
TXID from your wallet to your Duel.com deposit address
Step 5
Reviewer satisfied
Withdrawal released
Practical tips for each link:
- Exchange statements: export the official account statement or trade-history PDF/CSV from the exchange, showing your name, the dates and the amounts. Dashboard screenshots without your name are commonly refused.
- TXIDs: list them in a plain text note with date, amount, from-address and to-address. Reviewers can check them on a block explorer; so can you — see how to check a transaction on a block explorer.
- Wallet ownership: if asked to prove you control a self-custody address, a screenshot of the wallet showing the address and balance is often enough. Some reviewers accept a signed message. Never share a seed phrase or private key for this — no legitimate check requires it. See wallet security basics.
- Intermediate hops: if funds passed through a second wallet, include those TXIDs too. Gaps are what generate follow-up rounds.
- Privacy coins and mixers: a trail that disappears into a mixer or a privacy coin cannot be evidenced and is a common reason for a case to stall. Be honest about it and provide the pre-mixer origin.
How to respond
Read the request precisely
Note which period, which accounts and which deposits are in question. Answer that scope — no more, no less.
Write a short cover note
Three to six plain sentences: where the money originated, the route it took, and which attached document evidences each step. This alone prevents most follow-up rounds.
Gather originals
Official PDFs from banks and exchanges beat phone photos of screens. Keep file names descriptive.
Redact only what is irrelevant
Blacking out unrelated third-party transactions is usually fine; blacking out your name, dates, balances or the transactions in question is not. If Duel.com gives redaction guidance, follow it.
Check names and dates align
Documents must match your verified identity and cover the deposit period. A statement that ends the month before your deposits does not help.
Submit through the in-app flow only
Upload where the request tells you to inside your account. Never send SoF documents to an email address or chat that contacted you first.
Common reasons an SoF response is rejected
- Statements do not cover the period of the deposits in question
- Exchange records show a different name from the Duel.com account
- TXIDs listed do not actually connect to the Duel.com deposit address
- Third-party account or wallet involved with no explanation
- Unreadable, heavily redacted or edited PDFs
- Declared income is far below the volume and no other origin is offered
- Trail ends at a mixer or privacy coin with no earlier origin provided
If a response is refused, treat it like any other rejection: get the specific reason, fix exactly that, and resubmit once. See verification rejected.
What happens if you refuse
If you believe a request is unreasonable, the route is to cooperate to the extent you can, document everything, and then dispute: live chat, then support@duel.com, then third-party mediation such as Casino.Guru, then the Anjouan regulator. Mediators consistently ask whether the player supplied what was requested. A record of prompt, complete cooperation is your strongest position; a refusal is your weakest. The withdrawal pending guide covers how holds interact with payouts.
Privacy considerations
You are handing detailed financial records to an offshore operator. Duel.com's privacy terms commit to secure storage with restricted staff access, and that is the protection you have — contractual, not statutory. Reduce exposure sensibly: supply only the requested period, redact unrelated third parties, keep your own copy of what you sent, and once the account is closed request deletion via account data requests. Good record keeping makes future requests painless.
When to contact support
Contact support before submitting if the request does not specify a period or account, if your funds have a mixed or unusual origin (inheritance, long-held coins, winnings from another site), or if you cannot obtain a document it names. Contact support after submitting if several business days pass with no decision and no follow-up. Use the 24/7 live chat or support@duel.com, and include your registered email or username, the date of the request, the withdrawal amount and TXID on hold, a one-paragraph description of the origin of funds, and the list of document types you have ready — do not attach the documents themselves to chat or email.
Summary
A source of funds request is Duel.com's AML clause in action: rare, triggered by volume or pattern rather than identity, and always sitting in front of a withdrawal. For crypto, the winning response is an exchange statement in your name, the TXIDs linking that purchase to your Duel.com deposits, and — where asked — the bank record behind the purchase, tied together with a short cover note. Answer the exact scope, submit once through the in-app flow, keep copies, and never share a seed phrase or send documents to anyone who contacted you first.
Frequently asked questions
What is a source of funds request on Duel.com?
It is a compliance request asking you to show where the money you deposited originally came from — salary, savings, an asset sale, a crypto purchase on an exchange. Duel.com makes these requests under its anti-money-laundering obligations, typically after large or unusual volumes, and holds the related withdrawal until it is satisfied.
Is source of funds the same as KYC?
Related but distinct. KYC confirms who you are; source of funds confirms where the money came from and that it is not proceeds of crime. On Duel.com, which has no routine KYC, an SoF request usually arrives together with, or shortly after, an identity check.
What documents prove crypto source of funds?
An exchange account statement or trade history in your name, the on-chain transaction IDs linking that exchange withdrawal to the wallet you deposited from, and — if asked — the bank statement showing the fiat that funded the purchase. Mining payouts, salary paid in crypto or a documented sale also work with records.
Will Duel.com ask for my entire bank history?
Usually not. Requests typically cover recent months around the deposits in question, not lifetime history. Provide exactly the period and accounts requested — over-supplying unrelated accounts confuses reviewers and slows the case.
Can I refuse source of funds and still withdraw?
Realistically no. Duel.com's terms allow it to withhold withdrawals until a requested verification is completed, and refusal typically leaves the balance frozen. The dispute path (support, then mediation, then the Anjouan regulator) will ask whether you cooperated — so cooperate, once and fully.
