Exchange CARDCZK to Optimism (OP)

If an automated AML screening assigns a high-risk score to your transaction, the exchanger may pause the order and request supporting documentation — such as proof of funds, a wallet address history, or an explanation of the transaction's origin. In cases where the risk cannot be resolved, funds may be held for a compliance review period or returned to the sending address, minus any applicable network fees. To minimise the chances of an AML flag, send only from personal wallets with a clean on-chain history, and avoid addresses linked to mixers, darknet markets, or sanctioned entities.

Yes, this is possible. Most exchangers listed on Nadoswap operate without identity verification for smaller amounts; however, for larger transactions or where required by the exchanger's home jurisdiction, a KYC check may be triggered. This typically involves uploading a government-issued ID and, in some cases, a selfie for liveness verification. If avoiding KYC is important to you, look for exchangers that explicitly list "no verification" in their conditions — this detail is visible on each exchanger's listing before you commit to an order.

It depends on the rate type offered by the exchanger. With a fixed rate, the amount of OP shown at checkout is locked in — you'll receive exactly that figure regardless of market movement during processing. With a floating rate, the final amount is calculated when your CARDCZK actually arrives at the exchanger's wallet, so the payout may differ slightly from the initial quote. Always check which rate type applies before confirming — this information is displayed clearly alongside the exchange terms.

Swapping CARDCZK for OP on Nadoswap takes just a few steps. Enter the amount you want to send — the aggregator instantly scans all connected exchangers and surfaces the best available rate. Pick the offer that works for you, provide your OP receiving details, and follow the on-screen instructions for your chosen service. The entire process typically completes in 5 to 30 minutes, though exact timing depends on network conditions and the specific exchanger's processing speed.

Once your transaction has been confirmed on the blockchain, the exchanger begins processing your order immediately. In most cases, OP arrives within 5 to 30 minutes. If you're cashing out to a bank card or bank account, allow up to one business day — processing times vary by receiving bank and payment corridor. If funds haven't arrived after the timeframe shown in your order confirmation, contact the exchanger's support team and provide your order ID for a status check.
