Crypto Payment Processing: Fiat Rails for Web3

Crypto businesses need fiat on-ramps and off-ramps. Here's how to navigate the banking challenges.

The Challenge

Crypto businesses need fiat rails - ways for customers to buy crypto with cards or bank transfers, and ways to convert crypto back to fiat. Traditional banks and PSPs are often reluctant.

Business Models That Need Fiat

  • Exchanges (on-ramp and off-ramp)
  • NFT marketplaces (card payments)
  • Crypto wallets (card deposits)
  • DeFi platforms (fiat access)
  • Mining operations (revenue conversion)

Banking Challenges

Risk Perception

Banks view crypto as high-risk due to volatility, regulatory uncertainty, and AML concerns.

MCC Classification

Crypto often falls under MCC 6051 (Non-Financial Institutions), which many acquirers restrict.

Regulatory Uncertainty

Different jurisdictions have different rules. Acquirers prefer clarity.

Finding Solutions

Specialized PSPs

Some PSPs specifically target crypto businesses. They understand the vertical and price accordingly.

Licensing

Proper licensing (money transmitter, crypto licenses) opens more doors. Regulated entities have better banking access.

Stablecoin Settlement

Some PSPs offer settlement in stablecoins (USDC, USDT), reducing volatility risk.

What to Expect

  • Processing rates: 4-8%
  • Enhanced due diligence
  • AML/KYC requirements
  • Transaction monitoring obligations
  • Potential volume limits

Compliance Considerations

  • Travel Rule compliance
  • Wallet screening
  • Transaction monitoring
  • Sanctions screening
  • Record keeping

Key Takeaways

  • Fiat rails exist for crypto but require specialist PSPs
  • Licensing improves banking access significantly
  • Expect higher costs and more compliance requirements
  • Stablecoin settlement reduces some volatility concerns
  • AML/KYC is non-negotiable
