Crypto cards are evolving fast. The early generation focused on one thing: converting crypto into fiat so you could spend it at a store. That model worked, but it never fully embraced the core idea of DeFi.
The newer generation is different. These cards are starting to behave less like prepaid debit cards and more like extensions of on-chain finance. But “DeFi card” means very different things depending on who’s building it.
MetaMask Card and Ether.fi Cash Card are both DeFi-native. Both use self-custody. Both target Ethereum-focused users. But the user they’re actually designed for is completely different — and choosing the wrong one for your situation is an expensive mistake to make after the fact.
This comparison focuses on a question most reviews skip: who is each card actually built for, and what does the experience look like six months in?

The Core Trade-Off
The fundamental difference between these two cards isn’t the cashback percentage or the supported assets. It’s how much complexity you’re willing to manage for a better yield outcome.
MetaMask Card is designed for accessibility. It works like a debit card. You connect your MetaMask wallet, spend ETH or stablecoins, get 3% cashback, and move on. The friction is minimal. There’s no yield strategy to manage, no protocol mechanics to understand, no position to monitor. For the 30+ million MetaMask users who interact with DeFi daily but just want their spending card to work cleanly, that simplicity is the point.
Ether.fi Cash Card takes a different stance entirely. It’s a credit card backed by crypto collateral, not a debit card. Your USDC stays in Ether.fi’s system generating yield while the card draws a credit line against it. The 15% cashback figure is achievable, but it’s tied to Ether.fi’s points system and protocol participation — not a flat percentage on every transaction. Users who engage deeply with the Ether.fi ecosystem (staking weETH, participating in liquid restaking) get more out of it. Passive users get significantly less.
That’s the real distinction: MetaMask Card rewards spending. Ether.fi Cash Card rewards protocol engagement.
MetaMask Card
MetaMask Card is the lowest-friction path from DeFi to everyday payments. It runs on Mastercard, connects directly to your MetaMask wallet, and lets you spend ETH, USDC, or USDT at any Mastercard merchant without moving funds to an exchange first.
The accessibility story matters here because MetaMask’s user base is broad. It includes hardcore DeFi traders, but also millions of people who primarily use MetaMask to interact with a handful of protocols and hold stablecoins. For that second group, the last thing they want is a spending card that requires them to understand restaking mechanics, monitor collateral ratios, or manage a points system. MetaMask Card doesn’t ask them to.
The 3% cashback is competitive for any crypto card category — not just self-custody. And for users in the EU or UK who upgrade to the Metal tier, the FX fee disappears entirely, making it genuinely cost-effective for international spending. Ether.fi Cash Card doesn’t even operate outside the US at this stage.
Key Features
- 3% flat cashback on all purchases
- 0% FX on Metal tier, 1% standard
- Spend ETH, USDC, or USDT directly
- Free ATM withdrawals up to $1,200/month
- Available EU, UK, and US
- No annual fee
Pros
- Flat 3% cashback — no protocol engagement required
- Works outside the US (EU and UK included)
- Zero learning curve for existing MetaMask users
- Debit structure means no credit line or collateral management
Cons
- Only three supported assets
- Lower theoretical cashback ceiling than Ether.fi
- Metal tier pricing not fully transparent upfront
Conclusion — MetaMask Card is the right choice for users who want a clean, low-maintenance spending card that works globally. The 3% cashback is guaranteed, the setup is minimal, and the geographic reach beats Ether.fi by a wide margin.
Ether.fi Cash Card
Ether.fi Cash Card operates as a credit card, not a debit card — a distinction that has meaningful implications. Rather than spending down a crypto balance directly, users deposit USDC into Ether.fi’s system, where it can generate yield through the protocol’s liquid staking and restaking infrastructure. The card then draws a credit line against that collateral.
The yield mechanic is the key feature. If your USDC is generating 5-8% APY through Ether.fi’s restaking layer while you spend against it, the economics of holding stablecoins change. You’re no longer choosing between deploying capital in DeFi or using it for payments — the card bridges both simultaneously.
The 15% cashback headline is achievable, but realistically it requires active participation in Ether.fi’s points programs and protocol incentives. For users who are already deep in the Ether.fi ecosystem and hold significant USDC positions, that ceiling is meaningful. For casual users or those new to restaking, the actual return will be considerably lower.
Key Features
- Credit card structure backed by USDC collateral
- Up to 15% cashback through protocol participation
- USDC generates yield while held as collateral
- Self-custody architecture via Ether.fi ecosystem
- Visa network (US only)
- No annual fee
Pros
- Yield-on-collateral model is genuinely novel
- Higher cashback ceiling for protocol-engaged users
- Capital stays productive even while serving as spending collateral
- Self-custody architecture maintained throughout
Cons
- US-only availability
- 15% cashback requires deep Ether.fi protocol engagement
- Credit model adds complexity vs simple debit
- ATM withdrawals cost 2% — unfavorable for cash access
Conclusion — Ether.fi Cash Card is the right tool for power users already embedded in the Ether.fi ecosystem who want their stablecoin collateral working while they spend against it. For everyone else, the complexity-to-benefit ratio tips toward simpler alternatives.
Which Card Wins for Which User
If you’re an active Ether.fi participant with substantial USDC and you’re comfortable managing credit-against-collateral mechanics, the Ether.fi Cash Card’s yield-while-you-spend model offers something MetaMask Card simply doesn’t. But you need to be US-based and genuinely engaged with the protocol to extract that value.
If you’re a MetaMask user who wants a spending card that just works — one that gives consistent 3% cashback without requiring you to understand restaking, monitor collateral positions, or stay inside a single country — MetaMask Card is the cleaner answer. It works in the EU and UK too, which immediately expands its addressable audience by a significant margin.
Conclusion
Two DeFi-native cards. Two very different user profiles. MetaMask Card optimizes for reach and simplicity — it’s the broadest-appeal self-custody spending card available today. Ether.fi Cash Card optimizes for capital efficiency — it’s a yield strategy with a card attached, designed for users who already know what liquid restaking is and want to run it continuously in the background while they spend.
The right choice isn’t about which card looks better on paper. It’s about which financial behavior you actually have.
