Sweepbase Reviews & Provider Details

Sweepbase is a free crypto card aggregator that compares 141 crypto debit and credit cards by their real fees instead of marketing headlines. For each card it surfaces ATM withdrawal fees, FX conversion spreads, staking or stake-to-tier requirements, cashback caps, yield rates on stablecoin balances, supported blockchain networks (Ethereum, Solana, Polygon, Base, Arbitrum, Bitcoin Lightning, and others), KYC requirements, and regional availability across the USA, European Union, United Kingdom, Canada, Latin America, Asia, and other markets. The site is structured around how people actually shop for a crypto card. Filters cover region, custody type (custodial vs self-custody), card network (Visa, Mastercard, Discover), funding currency (USDC, USDT, DAI), and persona (travel, daily spending, yield seekers, beginners, privacy-first). A built-in fee calculator estimates monthly cost across cards based on the user's spending profile and lets buyers see break-even points instead of relying on advertised cashback alone. Sweepbase keeps a transparent reference experience: no paywall, no email gate to read content, no affiliate-driven ranking. Editorial picks are flagged separately from algorithmic rating, and every card review surfaces pros and cons drawn from public terms of service, fee schedules, and verified merchant disclosures. The product targets self-custody users, frequent travelers, freelancers paid in stablecoins, and high spenders deciding between premium metal cards. Sweepbase is built on Next.js with the underlying data as a transparent CSV that anyone can audit. The card catalog updates as issuers publish new tiers or change fee structures.
