Project description:
"My web3-based e-commerce store is almost ready, yet the fiat checkout flow is still unreliable. I need the existing, partially built credit-card module replaced or refactored so it works through a modern gateway and clears payments every time.
The task
I want you to integrate a new credit-card processor—Stripe, Adyen, Braintree or a comparable provider—into the current codebase, link it to the order system, and make sure the entire flow (authorisation, capture, refunds, webhooks) is solid and secure. Front-end error handling and status messages must also update correctly so customers see instant feedback.
Why this matters
Crypto payments are already live, but I’m losing sales whenever someone tries to pay with a card. Moving to a proven gateway will solve that.
What I’ll share with you
• Full access to the repo and existing payment logic
• API keys for the new provider once we agree on the best fit
• Clear test cases for successful charge, decline, refund and webhook reconciliation
What I need from you
Show me projects where you have integrated credit-card gateways in production. Specifics on frameworks, SDKs or libraries you used are a plus, but the main thing I will weigh is your experience doing exactly this kind of integration.
Acceptance criteria
• New gateway processes live and test transactions without errors
• Orders, invoices and refund events sync perfectly in the database
• Client-side messages update in <2 s for all payment outcomes
• Code is clean, commented and delivered via pull request
If your background lines up and you can jump in quickly, let’s get this wrapped up so the store can finally go live." (client-provided description)
