The safe default. Backed 1:1 by cash and US treasuries, audited monthly. If a card says "spend stablecoins" — it probably means this one.

The most liquid stablecoin on earth. Bigger market cap than USDC, accepted everywhere, especially in Asia and LATAM. More controversial on reserve transparency.

Brand new. This is what MetaMask pays you cashback in. Built on Ethereum, issued through Stripe's Bridge infrastructure. Tied to the MetaMask rewards ecosystem.

USDC deposited into Aave that earns yield automatically. Hold this instead of regular USDC and your balance grows while you wait to spend. DeFi savings account energy.

On-chain euro and pound. If you're spending in Europe, your card converts to these. Regulated as e-money under EU law — as legit as stablecoins get.

The OG decentralized stablecoin. Not backed by a company — maintained by smart contracts and crypto collateral. For the "don't trust, verify" crowd.
