SDK & Browser Popup Design
Budget: $10 – $30 USD
Description:
We're finishing the visual design for a payment authentication popup experience (SDK login flow, similar in spirit to Google Pay's auth popups), and need a designer to take partially-completed source files across the finish line to a professional, industry-standard, ready-to-develop state.
Scope of Work
1. SDK / iframe authentication flow — 5 screens
Each of the 5 popup screens in the login flow needs to be finalized and delivered at all 5 EMV 3-D Secure (3DS2) standard challenge window sizes:
• 01: 250×400px
• 02: 390×400px
• 03: 500×600px
• 04: 600×400px
• 05: Full Screen
That's 5 screens × 5 sizes = 25 total artboards. Layouts must hold up cleanly at each size — no clipped buttons, no broken proportions — since these map directly to the challengeWindowSize / acsWindowSize parameters used by payment processors (Stripe, Braintree, etc.).
2. Browser extension login flow — 3 screens
3 popup screens, delivered at a single fixed size: 357×600px, the de facto standard used by wallet-style browser extensions (within the 25×25–800×600 range Chrome/Firefox permit for extension popups).
What We'll Provide
• Partially finished designs as Adobe Illustrator (.ai) source files for you to build from
• Access/onboarding to our self-hosted Matrix chat server (handled by our Codebase Coordinator)
• Instructions for delivering finished work into our self-hosted Penpot instance for review and payment release
What We Need From You
• Strong experience with fintech/payment or wallet-style UI (crisp, trustworthy, "industry standard" visual language — think Google Pay, Stripe Checkout, MetaMask)
• Comfort working in Penpot (or willingness to import/convert from Illustrator into Penpot)
• Ability to collaborate async over Matrix chat
• Attention to responsive/adaptive layout constraints across fixed pixel dimensions
Deliverables
• 25 finalized SDK popup artboards (5 screens × 5 sizes)
• 3 finalized browser extension popup screens (357×600px)
