Compliance & risk
Source of funds (SoF)
A source-of-funds request asks you to document where the crypto you deposited came from, typically after an AML flag.
Typical evidence: exchange withdrawal receipts, mining payouts, invoices, or a transaction trail. It is a compliance step, not an accusation, but it does delay the order until resolved or refunded.
On Swap.bz
Rare on Swap.bz and only triggered by a partner flag. Keep your order ID; support coordinates the outcome (completion or refund to your refund address).

AML (Anti-Money Laundering)
AML screening is the automated analysis of a deposit’s on-chain history to detect links to sanctioned addresses, hacks, mixers or other high-risk sources.
KYC (Know Your Customer)
KYC is the identity-verification process — ID document, selfie, sometimes proof of address — that regulated financial services require before serving a customer.
Refund address
The refund address is where the exchange returns your deposit if the swap cannot be completed.
