If an exchange asks for source of funds, you can provide the documentation to release your money, or — if you’d rather not — request a refund and move future activity to non-custodial no-KYC swaps that never ask, because they never hold your balance. Source-of-funds requests come from custodial platforms under AML rules. Compare 30+ no-KYC exchanges above or open XMR → BTC.

Why exchanges ask for source of funds
Custodial, KYC-regulated exchanges must run anti-money-laundering checks and can demand proof of where your crypto came from — payslips, trade history, invoices — before releasing larger amounts.
Your options
- Provide documents if you’re comfortable and want the funds released.
- Request a refund/withdrawal if you’d rather not, then move on.
- Switch to non-custodial swaps — they never take custody, so there’s no source-of-funds gate.
Avoiding it in future
Keep funds in your own wallet and trade via non-custodial no-KYC swaps. Set a refund address for a guaranteed exit on every swap.
What counts as source of funds?
Exchanges typically accept payslips, a trading-history export, an invoice, a sale contract, or a screenshot of an earlier purchase. Providing it usually releases the funds, but it also permanently ties that money to your identity on their records. If you’d rather not, withdraw what you can and move future activity to non-custodial swaps, where the question never arises because no one takes custody.
Frequently asked questions
Do no-KYC swaps ask for source of funds?
No — non-custodial swaps don’t hold accounts or take custody, so there’s no AML source-of-funds gate. Rarely a flagged deposit is reviewed mid-swap.
Should I give an exchange my source of funds?
That’s your call — provide it to release funds, or refuse and withdraw. For privacy, use non-custodial swaps going forward.
Can I avoid these requests?
Yes — don’t custody with KYC exchanges; trade wallet-to-wallet in the comparison.
Is refusing legal?
You can decline and withdraw; the exchange sets its own policy. Your tax duties are separate.
Can I refuse to give source of funds?
You can, but the exchange may hold the funds until you comply or withdraw. Non-custodial swaps avoid the situation entirely.
Is a source-of-funds request a scam?
On a regulated exchange it’s usually genuine AML compliance. Verify it’s the real platform (check the URL) before sending any documents.
