Change Bank card CZK to USD Coin OPTIMISM USDC

The rate is locked in when the order is created.

You always see the exact payout before confirmation. There are no hidden fees — the final USD Coin OPTIMISM USDC amount is calculated automatically with all charges included.

Yes. We use a secure HTTPS connection, anti-fraud systems, and manual review of suspicious operations. We are also an officially registered and regulated company in Bulgaria.

Funds are sent only after the incoming payment is confirmed. The rate is fixed in advance, protecting users from sharp market swings.

Minimum and maximum amounts depend on the direction, liquidity, and sending network.

Limits are displayed on the exchange page and update in real time. If you need to process an amount above the limit, contact support and we will review it individually.
