The problem BurgerBrows solves

The problem BurgerBrows solves
Current DeFi pain points

Complex wallet setup: Users must install MetaMask, manage seed phrases, and understand key management, which is a frequent source of errors and lost funds.

Fragmented experience: Users constantly switch between a browser and separate DeFi applications or wallet extensions, which interrupts workflows and increases friction.

Single-user limitation: Shared or public computers do not safely support multiple DeFi users without exposing credentials or requiring complex setup.

High barrier to entry: New users are intimidated by dense interfaces and unfamiliar terminology, making adoption difficult.

Testing difficulties: Obtaining testnet tokens and a reliable test environment is often cumbersome for learners and developers.

How BurgerBrows addresses these problems
Unified Web3 experience

BurgerBrows combines standard web browsing and DeFi functionality into a single application so users do not have to switch between browser tabs and external wallet apps. The result is a more cohesive, less error-prone workflow.

True multi-user support

Per-user wallet generation: The application creates a unique wallet for each device or user session.

Complete isolation: User data and keys are isolated so that funds and accounts remain private to each user.

Persistent profiles: Wallets and preferences persist across sessions, enabling safe use on shared devices such as internet cafes or family computers.

Zero-friction onboarding

Built-in faucet: Instant test tokens are available to let users practice without seeking external faucets.

Simplified DeFi operations: Common actions (deposit, yield collection, rewards) are accessible via one-click workflows with an approachable UI.

Real blockchain integration: Transactions occur on real testnets (for example, Sepolia) while keeping the interface beginner-friendly.

Enhanced security and usability

Device-based wallet generation: Wallets are derived using device-specific information to minimize accidental collisions.

Local key storage: Private keys are kept on-device rather than in a central database, reducing the risk of large-scale breaches.

User-paid gas: Users pay network fees directly, preserving the integrity of on-chain operations and avoiding centralized custody of funds.

Production-ready architecture: The system is built to support realistic transactions while retaining a safe environment for newcomers.

Primary use cases

DeFi education: An ideal environment for universities or bootcamps teaching blockchain fundamentals.

Internet cafes and public terminals: Enables multiple users to access DeFi safely from the same machine.

Family/shared devices: Allows family members to explore crypto without exposing each other’s accounts.

Developer testing: Provides a convenient testnet environment for dApp development and QA.

Onboarding new users: Eases the transition from Web2 to Web3 by removing setup friction.

Challenges we ran into

Challenges encountered
Multi-user wallet isolation

Problem: Ensuring truly unique wallets per user on a single machine was initially difficult. Naive approaches risked collisions or accidental sharing of key material between sessions.

Solution:

1-Derived a device/user fingerprint using system information (for example, machine hostname, OS, and the current OS user).

2-Generated a cryptographically secure identifier by hashing the fingerprint (SHA-256) and using a fixed-length prefix to form a user ID.

3-Implemented persistent local storage keyed by that ID to ensure separation and durability of each user’s wallet and data.
