Top up with USDC on Ethereum. Stablecoin price stability, Coinbase + Circle backing, ~5-minute settlement. No KYC.
USDC is the regulated US-Treasury-backed stablecoin issued by Circle. For users who specifically prefer Circle's compliance posture over Tether's, USDC is a 1:1 alternative for funding CryptoCardy. The dollar value, settlement time, and gas economics are essentially identical to USDT-ERC20.
For cost optimisation, USDT TRC-20 beats both USDC and USDT-ERC20 on fees (by ~20x). For value stability, both USDC and USDT-ERC20 are equivalent.
0x).USDC exists on multiple chains (Ethereum, Solana, Polygon, BSC, Avalanche, others). Our USDC deposit address is Ethereum-only. Do NOT send USDC from Solana or any other chain to our ERC-20 address  funds will be lost. We cannot recover cross-chain mis-sends.
Some users prefer Circle's regulatory posture and full attestation reports. For the 5-minute card-funding flow, the difference doesn't meaningfully manifest. Pick whichever stablecoin you already hold.
Circle can freeze USDC at the smart-contract level for specific addresses (typically following law-enforcement requests). Once your USDC has hit our deposit address and credited your balance, the funds are off the USDC chain  they live in your CryptoCardy balance and Circle can no longer affect them.
Your tx confirms slower. We credit on 12 confirmations, however long that takes.
Not via the USDC menu  only ERC-20. We support USDT on multiple chains (ERC-20/TRC-20/Solana/BSC) but USDC is ERC-20 only for now.
$5 equivalent. Practically, with ERC-20 gas costs, don't go below $50.
Pick a BIN above, top up with any of 20 cryptocurrencies, and your card is ready to use the moment the deposit confirms.
