Project: Bitcoin Wallet Simulator for Ledger Nano S Plus
5000 USD Project goal:
To develop a demonstration application for Ledger Nano S Plus that mimics the interface and behavior of the official Bitcoin application. The application should be non-functional in terms of transactions — without the ability to send funds or perform cryptographic operations.
Requirements:
1. Recreate the interface and user experience of the official Bitcoin application for Ledger, including:
• Displaying a static wallet address
• Simulating transaction history
• Displaying a static balance
2. The application must display a predetermined Bitcoin address that:
• Is generated randomly or taken from open sources
• Is not associated with assets or real accounts
3. The balance should be displayed as 122.97 BTC (for demonstration purposes only).
4. All transaction-related functions must be disabled. When a user attempts to send funds or make a transfer — display the following message:
“This is a demonstration wallet. Outgoing transactions are temporarily disabled due to an update of the identification protocol.
Expected reactivation date: 04.07.2025.”
Additional notes:
• The application is intended solely for demonstration, UI testing, or educational purposes.
• No private keys, real accounts, or interaction with the network are used.
• All wallet behavior is simulated or set statically.

161 0 1 30 days5000 USDHello Rama,
Thank you for the opportunity. I'm a professional blockchain developer with strong UI/UX skills, and I’d be excited to support your project. Your idea is unique and truly interesting, and I’d love the chance to help lead and bring it to life. As this is our first interaction, I want to express my full commitment to delivering my best work. I value long-term collaboration and aim to build a strong, trusting relationship with you.
To start, I'm not focused on high compensation I’d be comfortable with a basic living salary of $1.5k/month. After we build mutual understanding over the first few months, we can revisit the terms together. I’m even willing to work one week for free if you'd like to evaluate my skills firsthand. I’m currently working on a long-term project called DISCO.FAN, which you’re welcome to check out.
Looking forward to the possibility of working together and building something great.
Warm regards,
