DUALKEEPAbout DUALKEEP
DUALKEEP is a cryptocurrency payment gateway built for businesses that want to accept crypto without becoming crypto experts. A buyer pays in the coin they hold; the merchant sees a USD balance the moment the payment confirms. No wallet setup, no exchange accounts, no volatility sitting on the merchant's books.
What we do
- Payment gateway - a hosted checkout and e-commerce plugins that accept Bitcoin, Ethereum, USDT and 15+ other assets across 9 blockchains.
- Instant USD settlement - confirmed payments credit the merchant's USD balance immediately, at a flat 0.4% fee with no setup or monthly costs.
- Crypto invoicing - invoices delivered as a link, an email, or a QR code, with instant payment notifications and webhooks.
- Payouts and custody - merchants withdraw to their own wallets whenever they like, while platform funds are held on secured custody rails.
How we keep funds safe
Every invoice gets its own deposit address derived from the platform's treasury. Operating balances are kept deliberately lean: deposits are swept on a schedule, the bulk of funds is moved to cold storage, and an automated reconciliation process continuously verifies that on-chain holdings cover every merchant balance. Sensitive key material is encrypted at rest and production access is tightly restricted.
Why we built it
Accepting crypto still usually means choosing between complexity (running your own wallet infrastructure) and cost (processors taking 1% or more). We think a business should be able to create an account, drop a checkout into their store, and get paid - in minutes, at a fee that rounds to nothing. That is the product we are building, and the lineup is growing: point-of-sale, subscriptions, installment payments, and a white-label gateway are on the roadmap.
