Using Tangem Pay
Do I need to convert crypto to fiat before spending?
No. You don’t need to convert to fiat, but you do need to deposit USDC (Polygon network) into your Tangem Pay account.
Your Tangem Pay card uses this on-chain USDC balance to settle real-world purchases. When you make a payment, the corresponding amount of USDC is automatically deducted from your smart contract account and processed through Visa in U.S. dollars, while your balance stays on-chain and non-custodial.
What cryptocurrencies are supported for spending?
Right now, Tangem Pay allows you to use native USDC on the Polygon network. The choice of Polygon stems from its low transaction costs and high speed, which are critical for scenarios where many small trades happen and timing matters.
Support for more stablecoins and networks is coming soon in future updates.
How do I fund my Tangem Pay account?
You can fund your Tangem Pay account by clicking the ‘Add funds’ button and sending native USDC (Polygon) from your Tangem Wallet.
Can I withdraw funds back to my wallet?
Yes. Your balance is held in a smart contract you control. You can withdraw any unused USDC (Polygon) back to your Tangem Wallet at any time.
Are there any fees?
There are no transaction fees or monthly account fees for using Tangem Pay. However, the following charges may apply:
— Foreign exchange markups if you spend in a currency other than USD.
— Polygon gas fees when topping up your account with USDC (subject to network conditions). These are fees paid to the network, not charged by Tangem.
— ATM withdrawal fees may apply once this feature becomes available.
Are there any spending restrictions with Tangem Pay?
You can use your card for online and in-store purchases at merchants that accept Visa. Currently, the card cannot be used at ATMs, and only prefunded USDC (Polygon) is supported. Spending directly from other tokens or blockchains is not currently available.
What happens when I make a payment with Tangem Pay?
When you make a purchase, the equivalent amount of USDC is deducted from your smart contract account and settled in USD via Visa. If a transaction is declined, your funds remain untouched. Pending or reversed transactions will follow standard Visa network timelines.
