What is conditional KYC?

Most instant-swap providers don’t ask for ID up front. Many can still ask for it later, if a transaction trips their risk checks. That is conditional KYC, and it’s worth understanding before you send.

No account doesn’t mean no verification

“KYC” (know your customer) means checking who a customer is. Instant-swap services usually skip accounts, but each one runs automated risk checks and keeps the right to ask for verification. Here is what each provider WalletExchange compares says in its own words.

  • ChangeNOW No registration for standard swaps. An automated risk system checks all transactions. Verification, run through Sumsub, is used “only when necessary”, and “each KYC case is handled individually.”
  • SimpleSwap Most crypto-to-crypto swaps need no account. It may request KYC or more information in certain cases. A swap showing “Verifying” means you need to contact support.
  • StealthEX No sign-up, and no KYC for swaps unless your wallet is blacklisted by liquidity providers or the transaction is considered suspicious. Its formal AML policy also sets due-diligence thresholds, including transactions over $32,000.
  • SideShift No user accounts. Third-party risk tools check where deposits come from and where payouts go. Flagged shifts are paused for human review, and serious flags require verification before a refund is processed.
  • Exolix No account needed. Its AML/KYC policy is risk-based: a review can be triggered by the amount, how often you trade, blockchain analysis, sanctions screening or geography, and may ask for ID, a selfie, proof of address and proof of source of funds. It can hold a transaction until the review is done. It says it won’t ask for KYC just to fix a transaction error, unless the deposit itself was flagged.
  • NEAR Intents No account and no ID step for people swapping. Instead, swaps are screened: a flagged swap can be refused, delayed or frozen, and its terms say it has no obligation to refund. In September 2026 it froze about $503,000 linked to the Bitget hack, pending legal action. Source: 1Click terms of use.

Our experience so far

So far, no exchange made through WalletExchange has been held for identity verification by any provider. That matches what the providers describe: checks are the exception, triggered by risk flags, not a routine step.

It is still our experience, not a promise. Every provider keeps the right to ask for verification, and a single flagged deposit is enough to trigger it. Plan as if it could happen to you.

What usually triggers a check

The providers name the same broad triggers: funds linked to theft, fraud or sanctioned addresses, unusual transaction patterns, large amounts, and legal requirements. Apart from StealthEX’s policy thresholds, none of them publish exact trigger amounts. Nobody can promise a particular swap won’t be reviewed, including us.

What happens if you’re flagged

The exchange is paused while the provider reviews it. You may be asked for a photo ID, proof of address, information about where the funds came from, or a selfie check. If verification is declined or fails, the usual outcome is a refund to your refund address, often minus network fees. ChangeNOW’s FAQ, for example, says failed-KYC refunds are made within 24 hours. A refund isn’t guaranteed in every case, and serious flags can take longer.

Why these checks exist

Swap providers are generally treated as virtual asset service providers under anti-money-laundering rules. International standards from the Financial Action Task Force (FATF) include the “travel rule”, which requires providers to share sender and recipient details with transfers. FATF’s reference threshold is 1,000 USD or EUR, but countries set their own: the EU, for example, applies it with no minimum. Rules differ by country and keep changing, which is one reason providers keep verification in reserve.

Where you are matters

Every provider restricts some locations, and the lists differ. ChangeNOW’s terms send residents of certain jurisdictions, including the EU and the United States, to its account-based ChangeNOW Pro service, where KYC is mandatory. SideShift is not available in the United States, among other places. Always check your chosen provider’s terms for restricted locations before you send.

How WalletExchange shows this

Every quote has a “Privacy & provider details” panel summarising what each provider’s own terms say about accounts, verification and restrictions, with sources and the date we last reviewed them. A provider’s KYC policy never moves it up or down the ranking: quotes are ordered only by what you would receive. We don’t call any provider “no-KYC”, because none of them promise that.

Before you send

  • Read the provider’s terms for larger amounts Size is one of the most common review triggers.
  • Always give a refund address It is where your funds go if a review ends in a refund.
  • Know where your funds came from If you’re asked, a clear answer speeds up a review.
