Fohle – Redefining Crypto Wallets for Everyone

‍Overview

Fohle aimed to create a user-friendly crypto wallet that bridges the gap between complex blockchain technology and everyday users unfamiliar with crypto concepts. Their vision was ambitious: to make crypto accessible for everyone—young, old, tech-savvy, or tech-averse. They approached Spawn Solutions with a basic design concept and a goal to build an MVP, seeking both technical expertise and strategic guidance.

‍

The Challenge

Fohle needed to overcome several key challenges to achieve their vision:

1. Simplifying Crypto Onboarding: Traditional crypto wallets rely on private keys and mnemonics—technical concepts that alienate beginners. The wallet needed frictionless user experience to eliminate these barriers.
2. Building from Scratch: They lacked a clear technical roadmap, requiring support from discovery to deployment.
3. User-Centric Design: Their initial design concept was underdeveloped and not optimized for intuitive user experiences.
4. Early-Stage Development Decisions: The wallet needed scalable technology while prioritizing fast delivery for validation purposes.
5. Blockchain Complexity: Seamlessly integrating blockchain functionality while abstracting its complexities for users.

Our Solution

1. Simplifying Access with Account Abstraction

We advised Fohle to move away from traditional mnemonics and adopt account abstraction to enable simple and familiar login options, such as:

• Google, Apple ID, and email authentication.

This approach ensured the wallet was intuitive and accessible to users unfamiliar with crypto, aligning perfectly with the client’s mission to demystify blockchain.

2. Comprehensive Discovery Phase

During the discovery phase, we:

• Clarified the product’s architecture and technological needs.
• Collaboratively defined the roadmap for delivering a functional MVP.
• Balanced early-stage flexibility with a future-ready structure.

Our collaborative workshops helped refine the vision and finalize the optimal technical approach.

3. Cutting-Edge Technology Stack

We chose technologies tailored to Fohle’s needs and growth potential:

• Frontend: Built as a Progressive Web App (PWA) using React, ensuring it could run on mobile devices without app store dependencies. This decision provided:
  
  • Faster go-to-market speed.
  • Simplified maintenance for the client.
• Backend: Implemented using Deno, a high-performance alternative to Node.js.
• Database: Selected MongoDB for its flexibility in early development stages, with plans to migrate to a more structured database as the business scales.

4. Blockchain Integration

To handle blockchain functionality and decentralized finance (DeFi) capabilities, we:

• Developed smart contracts in Solidity on EVM-compatible chains (Sepolia testnet, transitioning to Arbitrum mainnet).
• Provided a decentralized exchange (DEX) feature built on Uniswap Protocol, enabling users to swap coins and provide liquidity.
• Integrated APIs for real-time blockchain and financial data:
  
  • Moralis and Etherscan for blockchain data.
  • Binance for crypto prices.
  • Frankfurter API for fiat currency data (directly linked to the European Central Bank).

5. Enhancing the User Experience

Fohle’s initial design concept required significant refinement to align with their goal of user accessibility. Our UI/UX designer:

• Improved the user interface to make navigation intuitive for crypto novices.
• Adjusted designs for account abstraction and added missing elements, saving the client time and resources.
• Delivered these enhancements as a value-added service without additional cost, fostering trust and collaboration.

6. Future-Ready Architecture

From day one, we planned for scalability:

• Frontend: Proposed migration to Next.js in future phases to improve performance and SEO as the product scales.
• Backend: Built a modular architecture to accommodate future feature expansions.
• Database: Designed a migration plan from MongoDB to a more robust database when the product matures.

Results

Key Deliverables:

• A functional MVP with intuitive login and onboarding.
• Blockchain and decentralized exchange (DEX) integration.
• A polished and user-friendly interface tailored to crypto beginners.
• A scalable architecture ready for future growth.

Early Impact:

1. User Accessibility

• Simplified onboarding: Account abstraction allowed users to log in via email or third-party providers, removing the need for mnemonics and private keys.
• Crypto for everyone: The wallet became accessible to users with zero blockchain experience.

2. Cutting-Edge Technology

• Delivered the MVP using modern tools like Deno and Account Abstraction, ensuring speed, scalability, and innovation.

3. Cost-Effective Launch

• Achieved a high-quality MVP by using MongoDB and PWA, striking a balance between early-stage flexibility and performance.

4. Future-Proof Architecture

• Set the foundation for scaling with plans for Next.js migration and database upgrades, ensuring the wallet evolves with user needs.

5. Strategic Partnership

• Fohle relied on our guidance for both technical execution and business strategy, enhancing their confidence in scaling the product.
