BitQube & QUBX Wallet + Token Listing Portal

Project Title: Develop Open-Source BitQube & QUBX Cryptocurrency Wallet with Token Listing Portal

Project Overview

We are looking for an experienced blockchain wallet developer or development team to build an open-source, non-custodial cryptocurrency wallet supporting the BitQube blockchain and QUBX blockchain.

The wallet should provide functionality similar to Trust Wallet, allowing users to manage native coins and import tokens using their contract addresses.

Key Requirements

1. Multi-Blockchain Wallet

* Support the native BitQube (BTQ) blockchain.
* Support the QUBX blockchain (Chain ID: 6004).
* Send, receive and securely store supported assets.
* Display balances and transaction history.
* Support mobile applications and/or web wallet, as proposed.

2. Token Import Feature

* Allow users to import tokens by entering their contract address.
* Automatically retrieve token name, symbol, decimals and balance wherever supported.
* Support compatible tokens created by third parties on both blockchains.
* Display warnings for unverified or potentially suspicious tokens.

3. Permanent Token Listing Portal

* Allow token creators to submit their token contract address.
* Enable logo uploads, preferably 256 × 256 PNG.
* Collect token name, symbol, description, official website and social media links.
* Verify submissions before adding them to the public token directory.
* Maintain a permanent listing without recurring fees, subject to security, legal and fraud-related removal requirements.
* Allow authorized creators to update logos and project information.

4. Security Requirements

* Non-custodial architecture: users control their private keys.
* Secure key generation, backup and recovery.
* No collection or storage of users’ seed phrases on our servers.
* Secure integration with blockchain nodes and RPC endpoints.
* Open-source code with documentation and security testing.

5. Administration Panel

* Review and approve token submissions.
* Manage token logos and metadata.
* Flag suspicious tokens and mark deprecated assets.
* Maintain listing and verification records.

Deliverables

* Complete source code and intellectual property handover as agreed.
* Mobile app and/or web wallet.
* Token listing portal and administration dashboard.
* Integration with both blockchain networks.
* Deployment instructions, technical documentation and testing.
* Support for publishing the open-source repository.

Developer Qualifications

Please provide:

* Previous cryptocurrency wallet projects or portfolio.
* Experience with EVM-compatible chains and native coin wallets.
* Recommended technology stack.
* Estimated development timeline and milestone-based pricing.
* Security audit arrangements and post-launch maintenance costs.

Important: Please review both blockchain protocols before quoting. We need a working wallet, not just a UI design or prototype. Clearly identify any required blockchain modifications, third-party services or additional costs.

Please submit your proposal with relevant experience, estimated cost and delivery schedule.
