Designing a Stablecoin-Powered Global Payments Platform for Modern Businesses
Onion Finance — B2B Global Payments & Web3 Infrastructure
Overview
Onion Finance is a B2B-focused fintech platform enabling businesses to move money globally using stablecoins, manage multi-currency wallets, and onboard compliantly across borders.
The goal was to abstract complex financial and crypto infrastructure into a product that felt reliable, operational, and business-ready — not experimental.
As the platform evolved, speed and clarity became critical to adoption and trust.
The Challenge
Cross-border payments felt opaque and unpredictable
Businesses struggled to understand payment status and settlement stages
Onboarding and compliance flows caused drop-offs
Stablecoin infrastructure added cognitive overhead for non-crypto-native users
Operational complexity slowed internal teams
My Role
Product Design Lead
Product Strategy · UX Architecture · Dashboard Design · Design System · Cross-team Collaboration
What I Did
Audited end-to-end business onboarding and payment workflows
Re-structured onboarding to separate account setup from compliance review
Designed clear, step-based payment flows with transparent status states
Built a scalable dashboard system for balances, transactions, and reporting
Simplified complex stablecoin concepts into familiar fintech patterns
Collaborated closely with founders, engineers, and compliance teams to balance UX and regulation
Outcomes & Impact
~3× increase in completed business onboarding flows
25–30% reduction in failed or delayed cross-border payments
30–35% faster settlement times through clearer payment execution paths
~40% reduction in support tickets related to payment status and visibility
Improved confidence for businesses using stablecoin-based rails without crypto friction
Key Takeaway
For infrastructure-heavy fintech products, users don’t need to understand the rails — they need certainty.
Clear workflows and transparent status build trust faster than advanced features.
