Beautiful DeFi. Zero friction.

We craft clean, familiar interfaces so anyone can swap, stake or earn without a PhD in crypto. DeFi deserves better design.

DeFi shouldn’t feel like filing taxes. At SmoothDeFi we craft friction-free user interfaces for protocols, wallets and DAOs so that anyone—from first-time traders to hardcore yield farmers—can move value at the speed of thought.
We’re a boutique London-based team of designers and front-end engineers who have shipped production code to Ethereum, Arbitrum, Solana and, yes, even Bitcoin L2s.
If you need pixel-perfect React dashboards, audited smart-contract front ends or a full design system that screams credibility on crypto Twitter, you’re in the right place.

We Build for Speed, Security, and Simplicity

DeFi users are smart — but they’re also impatient.

Why UX Is Your Unfair Advantage in DeFi

Gas fees and tokenomics may grab headlines, but the highest TVL protocols all share one thing: seamless onboarding.

A 2024 Bain & Co. study found that every extra click in a crypto swap flow drops completion rates by 18 %. Poor UX isn’t just inconvenient—it’s a direct drag on volume, liquidity and community growth.

SmoothDeFi embeds UX research, accessibility and performance optimisation into every sprint.

We test flows with both power users and “crypto-curious” newcomers to surface the unknown unknowns that cause rage-quits.

The result? Interfaces that feel as trustworthy as they are permissionless—helping your project climb the “Safety & Usability” leaderboards on DeFiLlama and Zealy quests.
