Build Turnkey Payment System with Rotating On-Ramps and Neutral Checkout
Budget: $500 – $1,000 USD
Develop a fully configured payment system. Swedish customers pay in SEK with Visa, Mastercard, Klarna credit cards, or Revolut credit cards via payment links. I receive USDT/USDC in my crypto wallet. Uses five rotating third-party on-ramps to prevent flagging by card issuers. Includes neutral checkout with logo and secure dashboard for managing links, tracking rotation, and monitoring payment flows. Must be turnkey, tested, no manual setup. I will complete KYC for on-ramps.
Requirements:
Checkout Page:
• No crypto terms (e.g., “crypto,” “blockchain,” “wallet”).
• Payments in SEK.
• Accepts Visa, Mastercard, Klarna credit cards, Revolut credit cards.
• Displays my logo for credibility.
• Mobile-optimized, user-friendly.
• No customer KYC/registration.
• Flow: Customer clicks payment link, enters card details, completes payment.
On-Ramp Integration:
• Five third-party on-ramps for card payments.
• Each must:
• Accept Visa, Mastercard, Klarna credit cards, Revolut credit cards.
• Pay USDT/USDC to my crypto wallet (no bank account).
• Use neutral Merchant Category Codes (e.g., e-commerce) to avoid flagging.
• Developer selects/configures five on-ramps compatible with Klarna/Revolut credit cards.
• APIs/webhooks to track transactions/status.
Rotation Logic:
• Different on-ramp per transaction (e.g., five payments cycle through five on-ramps).
• Distribute transactions to reduce flagging risk.
• Prioritize on-ramps by approval rate.
• Auto-switch if an on-ramp fails/declines.
• Manual on-ramp disable option in dashboard.
Admin Dashboard:
• Secure login with two-factor authentication.
• Features:
• Create payment links with SEK amounts.
• Upload/manage checkout logo.
• View transactions (date, SEK amount, card type, on-ramp, USDT/USDC payout).
• Track rotation (which on-ramp used per transaction).
• Monitor payment flow (e.g., status, approval rate).
• Export transactions to CSV.
• Web-based, simple interface.
• Hosted on my server (e.g., Ubuntu VPS), full source code provided.
Reliability:
• Prevent flagging by Klarna/Revolut credit card issuers long-term.
• Neutral checkout/rotation avoids detection as crypto-related.
• Add new on-ramps via API if one is flagged.
• Documentation for adding on-ramps.
Security:
• Encrypt data (HTTPS, AES-256).
• Protect against SQL injection, XSS.
• Log login attempts in dashboard.
Delivery:
• Complete system (frontend, backend, dashboard).
• Test all on-ramps with Klarna/Revolut credit cards.
• Includes:
• System installed on my server.
• Full source code.
• Documentation: dashboard use, add on-ramps, troubleshoot.
• 1-month support for bug fixes.
• Test environment before delivery.
Constraints:
• No Swedish/EU bank accounts (crypto payouts only).
• No crypto terms visible to customers.
• All on-ramps support Klarna/Revolut credit cards.
• No manual setup from me.
• I complete KYC for on-ramps.
Developer Requirements:
• Experience with payment systems/on-ramp integrations.
• Knowledge of avoiding flagging by card issuers.
• Proven turnkey solution delivery.
Core Challenge and Solution: The key challenge is ensuring payments via Klarna and Revolut credit cards are not detected as crypto-related, preventing flagging or blocking, even under scrutiny like customer complaints. The solution is selecting third-party on-ramps with precise configurations to process transactions smoothly and inconspicuously.
