You may wonder why USDC and USDT stand out among stablecoins for card payments. These two stablecoins offer unique advantages that make them popular choices for stablecoin top-ups. The table below highlights their key features and adoption context:
Stablecoin | Key Features | Adoption Context |
|---|---|---|
USDC | Highly regulated, widely adopted across platforms | Preferred by enterprises and institutions |
USDT | Most widely used stablecoin globally, ideal for trading and fast settlements | Recognized for its extensive use in crypto transactions |
USDC provides strong regulatory backing and transparency. USDT leads in global usage and liquidity. You can trust both for reliable card funding.
Stablecoin top-ups let you add funds to your crypto card using digital dollars like USDC or USDT. You send stablecoins to your card provider. The provider converts them to fiat currency, so you can spend at any store that accepts regular cards. This process gives you flexibility and speed.
Damilola Payne from MoonPay explains, "Ultimately, from a user perspective, you don't care. You have an outcome … a goal, a job to be done and what you want to do is have the infrastructure that you use to solve all the problems along the way, so that you can get from point A to point B."
You do not need to worry about complex conversions. The provider handles everything behind the scenes.

The platform supports both USDC and USDT, ensuring fast, secure, and user-friendly transactions.
You want your funds to stay safe and stable when using stablecoin top-ups. USDC and USDT aim to keep their value at $1, but sometimes market events can cause brief changes. Here are some recent incidents:
In 2023, USDC dropped below $1 for a short time during a banking crisis. The price recovered quickly.
USDT has faced scrutiny about its reserves, but it has maintained its peg through most market shocks.
You should know that liquidity concentration can affect stablecoin top-ups. If too many users rely on one stablecoin, sudden withdrawals may cause price swings. Both USDC and USDT have large market caps and strong liquidity, which helps protect your funds from major risks.
You expect secure transactions when topping up your crypto card. USDC and USDT use blockchain technology, which records every transfer and makes it hard for hackers to steal funds. You benefit from transparency because you can track your stablecoin top-ups on the blockchain.
Issuers must protect their reserves and follow strict audit practices. You can see the latest audit results in the table below:
Stablecoin | Issuer | Audit Frequency | Reserve Composition |
|---|---|---|---|
USDC | Circle | Monthly | U.S. Treasury securities and cash |
USDT | Tether | Quarterly | U.S. Treasury securities, short-term repurchase agreements, money market funds, cash, non-U.S. Treasury bills, corporate bonds, precious metals, bitcoins, other investments, secured loans |
Circle, the issuer of USDC, provides monthly audits and keeps reserves in cash and U.S. Treasury securities. Tether, the issuer of USDT, offers quarterly audits and holds a mix of assets. You gain confidence from these practices, but you should always check the latest reports before making stablecoin top-ups.
You need to trust that your stablecoin top-ups follow global regulations. USDC stands out for its regulatory clarity in the United States. USDT remains popular worldwide, but recent changes have affected its availability. For example, some European exchanges delisted USDT to comply with new rules.
UUPAY supports both USDC and USDT and follows strict compliance standards. You benefit from UUPAY’s US MSB license, Hong Kong registration, Swiss license, and ongoing Brazilian license application. UUPAY also holds PCIDSS Level 1 certification, which protects your card data. You can rely on 24/7 global support for any questions or issues.

USDT is not MiCA-compliant, so you may see restrictions in some regions. You get wide access, but you should stay alert for regulatory changes.
USDT (Tether) | USDC (formerly USD Coin) | |
|---|---|---|
