Unified Stack for Modern Crypto Cards Issuing
FinLego enables fintechs, wallets, and Web3 apps to launch cards that work seamlessly across fiat and crypto. From KYC to funding logic to card APIs, we handle the backend complexity. You get speed-to-market, full compliance, and total control over user experience - all under your brand.
Why Crypto Cards Projects Get Stuck - and
How FinLego Unblocks Them
  • Complex Wallet-to-Card Funding Flows
    Most platforms don’t natively sync wallet balances with card logic, causing delays or fragmented user experiences.

    →
    FinLego links card transactions directly to wallet balances (crypto or fiat) with real-time FX and routing logic.
  • Difficult Issuer Integration
    Working with BIN sponsors, processors, and networks can take 6-12 months.

    →
    FinLego connects you with pre-integrated issuer partners - card issuing, tokenization, and settlement in weeks.
  • Regulatory & Compliance Risk
    Card programs must be region-specific and compliant with both crypto and financial regulations.

    →
    Use FinLego’s built-in compliance layer with KYC onboarding, AML monitoring, and geo-blocking tools.
  • Limited Card Control & Customization
    Legacy platforms limit branding, user settings, and transaction logic.

    →
    FinLego gives you full control over design, spend limits, transaction types, and card features via API and dashboard.
