Blockchain mini-dapps on mobile
“Graham helped translate Minima’s complex decentralised technology into clear, usable product experiences. His ability to work closely with engineers while maintaining strong UX and product thinking made a meaningful impact on the platform.”
Project summary
I led UX/UI analysis, wireframing, prototyping and design-system creation for Minima’s blockchain MiniDapps ecosystem.
Product ideas needed to be validated against strict blockchain constraints before progressing to full design and build.
Designing performant applications without traditional user testing, while optimising for mobile and IoT environments.
Multiple MiniDapps were validated on Testnet and supported Minima’s MainNet launch in March 2023.
My role
I worked closely with Minima’s core team to explore, validate and design a suite of blockchain-based applications that could run fully on Minima’s lightweight Layer 1 protocol. My focus was UX/UI analysis, wireframing, prototyping and a design system that could support several MiniDapps.

Problem
Minima needed to prove that a full Layer 1 blockchain could support usable applications on mobile and IoT devices without compromising performance, file size or developer feasibility. Product ideas had to be checked against blockchain constraints before the team committed to detailed design or build.

Challenges
Designing for a blockchain-first environment introduced several constraints:
- Keeping UX patterns and UI components lightweight enough to run efficiently on-device.
- Designing multiple MiniDapps, including NFTs and peer-to-peer communication, without each one becoming a separate design language.
- Working without traditional user testing due to the confidentiality of the protocol ahead of MainNet launch, relying instead on developer validation and Testnet deployment.
Outcome
The resulting ecosystem included a diverse dashboard of MiniDapps ranging from NFTs to a peer-to-peer conversational app (Banter), all supported by a shared design system.
Despite the absence of traditional user testing, Testnet validation confirmed feasibility and usability, supporting Minima’s MainNet launch in March 2023. The work showed that blockchain applications could be made understandable even under strict technical and confidentiality constraints.
