ETH / BTC Hybrid L2

BOB / Build on Bitcoin

BOB is a L2 chain that lets developers build dApps on Bitcoin it combines Bitcoin’s security with Ethereum’s flexibility.


At BOB, I led the design of the entire product portfolio and the BOB Fusion airdrop campaign, focused on increasing on-chain liquidity and attracting developers. We used a user-centered design approach, testing frequently to ensure every decision met the needs of real users and the community. In addition to UX/UI design, various other assets were created, including pitch decks for VC presentations, conference print materials, social media visuals, animations, and no-code Webflow development for various landing pages.

Key Outcomes

The UX - UI design streamlined user flows, enhanced the developer experience, and contributed to:

Total Value Locked

£250M+

Unique Connected Wallets

500K+

Ecosystem Growth

100+ Apps

The Challenge

BOB was a new project with no UX foundation. We had to build everything from scratch, such as the brand identity, design system, onboarding UX, all the chain primitives like bridging, as well as a seamless dual-chain experience for BTC and EVM users.

The outcome

The outcome was a cohesive and scalable design system that served as the foundation for BOB’s brand and user experience. The Figma-based system streamlined the design and development process, enabling consistent front-end implementation across the dApp, social media, and marketing assets.

The dual wallet experience provided seamless interaction with both BTC and EVM chains, empowering users to maximize the platform’s functionality.


The airdrop campaign successfully attracted significant on-chain liquidity and kickstarted the ecosystem's growth.
