Project Overview
Filing taxes in the traditional world is already challenging—now imagine doing it in the Web3 space. With Taxman, users are guided through four simple steps to generate a complete tax report. Featuring a calming, visually appealing interface, this web app prepares the report by securely accessing your wallet, and the completed report is sent directly to your email, ready to be filed with your country’s tax authorities.
By securely connecting your wallet, Taxman aggregates data from multiple chains and wallets into one platform. Overcoming the complexities of permissions, multi-chain compatibility, and wallet integration, we’ve built a tool that is fast, reliable, and safe for users navigating the Web3 landscape.
- Streamlined Process: Complete your tax report in four easy steps with a user-friendly, visually appealing interface.
- Multi-Chain Support: Securely connect multiple wallets and access data across various blockchain networks.
- Secure and Reliable: Built with robust security to ensure the wallet connections and data are protected.
- Ready-to-File Reports: we delivered a tax report directly to emails, ready to submit to your country’s tax authorities.
Effortless Tax Filing in 4 Steps
Led the design and development of the BCard app, collaborating with the team on everything from UX/UI to defining the brand and communication strategy. Together with partners, I helped design the revenue model, leveraging interchange fees (1-2%) from card transactions to benefit users and communities. By pooling transaction volumes, DAOs unlock higher revenue rates, creating a sustainable funding model for projects. [Check here the documentation]
I also created lead-generating products like Taxman, a wallet tax calculator recognized with a Retro PGF-3 award [Check the project here]
My hands-on involvement ensured BCard’s technology stood out Web3 doesn’t have to be complicated; it can be simple, intuitive, and accessible for everyone.

Stress-Free Tax Filing Through Thoughtful Design
Clear, step-by-step guidance fosters a sense of control, while our modern glass-effect interface and calming backgrounds create a serene experience.
Research published in Frontiers in Psychology (2019) highlights that calming visuals reduce cognitive load, and the APA (2017) emphasizes that predictable systems alleviate anxiety by providing a sense of control. By combining structure and aesthetics, Taxman transforms a typically stressful process into a manageable and calming experience.

Great products don’t just work; they care.
I designed the flow not just to deliver functionality but to elevate the user experience with a unique, thoughtful twist. Beyond simplifying taxes, it incorporates a feature to help users manage stress—a button to shift focus and reset their mindset.
Inspired by Kaplan’s Attention Restoration Theory (1995).
Customizable Transaction Review
The user begins with a preview of all transactions, providing a clear summary without overwhelming detail. For specific entries, they can drill down into individual transactions, toggle between income or outcome, and verify data through Etherscan.
If they prefer a faster process, they can skip the detailed review and proceed directly to the final step to generate their tax report—offering both flexibility and efficiency.
