Accept crypto payments for your crypto business

The irony of the industry: crypto companies can't get payment processing. Banks debank you, Stripe restricts you, and acquirers call you high-risk. Flint is crypto-native — you're our home turf.

The problem

Why crypto companies get frozen out of payments

Card processors restrict crypto businesses

Exchanges, wallet services, NFT projects, and trading tools sit on restricted-business lists at Stripe, PayPal, and most acquirers. Approval is rare, revocation is common.

Debanking is an existential risk

Crypto companies lose bank accounts with 30 days' notice and no explanation. Building your revenue collection on fiat rails means building on ground that can vanish.

Card fees don't fit crypto margins

SaaS tools, signal services, and API products in crypto often run subscription models where 3–4% card fees plus dispute losses take a real bite — when you can get approved at all.

Your users have crypto; your checkout doesn't

Your customers already hold crypto — it's the one industry where that's guaranteed. Forcing them through a card checkout adds friction and loses sales to no one's benefit.

The Flint fix

How Flint serves crypto-native businesses

Payment rails that match your industry

Accept the assets your users already hold. No acquiring bank to convince that a trading-tools SaaS isn't a threat to civilization.

Subscriptions and one-time sales

Sell licenses, memberships, credits, or one-off products through hosted checkout. Webhooks notify your backend to provision access the moment payment confirms.

Developer-first API

REST API, signed webhooks, and hosted checkout links you can generate programmatically. Built by people who assume you'll integrate it, not just paste a button.

No debanking exposure on revenue

Your revenue arrives as crypto you control. A bank closing your account doesn't interrupt your ability to collect payments.

Stablecoin settlement for predictable books

Price in dollars, settle in USDT or USDC. Volatility stays out of your accounting while your checkout stays crypto-native.

FAQ

Crypto payment questions, answered

Why would a crypto business use a payment processor instead of just posting a wallet address?

A raw wallet address gives you no order tracking, no payment-to-customer matching, no underpayment handling, no webhooks, and no checkout UX. Flint handles per-order payment detection, confirmation tracking, and signed webhooks so your backend can provision access automatically — the difference between accepting crypto and running a business on it.

Which cryptocurrencies can I accept?

Flint supports the major coins your users actually pay with — Bitcoin, Ethereum, and leading stablecoins like USDT and USDC. Check the dashboard for the current full list, which expands over time.

Can I run recurring subscriptions for my SaaS or signal service?

Crypto has no card-style auto-pull, so subscriptions work on a renewal-invoice model: Flint generates payment requests per period, and webhooks tell your backend to extend or expire access. Most crypto SaaS products find renewal conversion is strong because their users prefer paying this way.

How do I keep volatility off my books?

Denominate prices in dollars and accept stablecoins as the primary payment method. USDT and USDC settle at face value, so your revenue records match your price sheet without exchange-rate noise.

How does provisioning work after payment — license keys, API access?

Flint sends signed webhooks on payment detection and confirmation. Your backend verifies the signature and provisions whatever the product is — license key, API credit, account upgrade. The docs cover the webhook flow with examples.

Is Flint itself going to debank me like everyone else?

Crypto businesses are Flint's core market, not a risk category we tolerate. We publish our terms, and legal crypto products and services are squarely inside them.
