Blendin : Web3 Wallet + NFT Marketplace · Client Project · Closed
Blendin was a Web3 platform built for crypto natives. One product, three surfaces: a self-custody wallet, an NFT marketplace for buying and selling, and a token exchange. The audience already understood wallets and gas fees. What they needed was a product that matched their expectations for speed, clarity, and control.
Challenge
Web3 products fail at the same places repeatedly.
Seed phrase setup is treated as a checkbox, not a critical moment. Users are handed 12 words, told to write them down, and moved on with no real sense of what losing those words means. Transaction confirmation screens bury the important details. Asset ownership flows feel fragile. And across the whole product, there is a persistent low-level friction: the interface never quite communicates that you can trust it.
For crypto natives specifically, that last point is the sharpest. They have seen enough rug pulls, phishing attempts, and poorly built interfaces to be suspicious by default. The design job was not just to make things look good. It was to make the product feel like it deserved their trust at every interaction.
My Approach
I worked through the product surface in order of trust criticality, not visual complexity.
The wallet came first because it is where the stakes are highest. Every decision about how to present a seed phrase, how to confirm a transaction, how to display a wallet address these are not UI details. They are moments where a single unclear label or a misplaced button can result in permanent, irreversible loss.
From there the marketplace and the overall design system followed. Once the trust logic was established in the wallet, applying it consistently across buying, selling, and browsing NFTs was a question of execution.
What I Built
Wallet Onboarding and Seed Phrase Flows
The seed phrase flow was redesigned around one principle: the user should finish this screen understanding exactly what these words are and exactly what happens if they lose them. Not as legal copy. As a designed experience.
This meant slowing the flow down deliberately at the right moments, separating the generation screen from the confirmation screen, and building in a verification step that required active recall rather than passive acknowledgement.
Transaction confirmation screens were rebuilt to surface what actually matters: what you are signing, what address it is going to, what the fee is, and what cannot be undone. No buried details. No relying on the user to know where to look.
NFT Marketplace
Designed the full buy and sell experience: browsing, collection views, individual asset pages, listing flows, and purchase confirmation. The challenge specific to an NFT marketplace for crypto natives is that they parse a lot of data quickly: floor price, last sale, rarity, owner history. The layouts needed to surface that density without becoming cluttered.
Brand and Design System
Built the Blendin brand from scratch alongside the product — visual identity, colour system, typography, and iconography. The design system covered all three product surfaces: wallet, marketplace, and exchange. Consistent component behaviour across such different interaction types required a system with clear rules, not just a component library.
Results
The project closed before launch. There are no usage metrics to report.
What exists is the complete design: a wallet onboarding system built around the real risks of self-custody, an NFT marketplace designed for users who read every detail, and a brand system that could have carried a serious Web3 product to market.
What this project shows
Most of my work is in fintech and fleet tech, where the design problems are about data density and decision support. Blendin was about something different: designing for irreversibility. When a transaction cannot be undone and an asset cannot be recovered, the interface carries real weight. That constraint made it one of the more demanding design problems I have worked on, regardless of the outcome.
