What is Crypto-Friendly Card Issuing
Crypto-friendly card issuing is the issuance of cards via API with the ability to fund the balance with cryptocurrency (USDT, USDC, BTC, ETH, and others). Conversion happens automatically during funding or at transaction time.
This is in demand for businesses that:
- Earn revenue in cryptocurrency (Web3, DeFi, NFT projects)
- Want to avoid traditional banks when funding ad budgets
- Operate in jurisdictions with limited access to banking services
Key Characteristics of Crypto-Friendly Providers
- Supported crypto: USDT (TRC-20/ERC-20), USDC, BTC, ETH, BNB
- Blockchain network: important — TRC-20 is cheaper than ERC-20 in fees
- Conversion speed: instant or with a delay
- Conversion fee: typically 1–3%
- KYC for end users: whether verification is required

FAQ
Is it safe to fund a card via USDT TRC-20? Technically safe — it's a standard transfer on the TRON network. Main risks: sending to the wrong address (always check the first and last characters) and USDT volatility (minimal, as it's a stablecoin).
Are there issues with tax reporting of crypto funding? Depends on jurisdiction. In most countries, converting crypto to fiat is a taxable event. Providers usually supply statements for accounting purposes. Consult a tax advisor.
Do crypto-funded cards work in Google Ads? Yes, if the card is a standard Visa/Mastercard with a valid BIN. Google and Facebook do not see the funding source — they only see card details during authorization.
