Non-Custodial DEX for BitQube Ecosystem

BitQube Decentralized Trading Engine

We are looking for an experienced blockchain developer/team to develop a non-custodial decentralized order-book trading platform for the BitQube ecosystem.

Initial Trading Markets

The MVP will support only:

* BTQ / USDT
* BTQ / QUBX

The objective is to provide a simple decentralized trading platform for BitQube miners, holders and ecosystem users.

Core Requirements

* Central Limit Order Book (CLOB)
* Buy and Sell orders
* Market and Limit orders
* Order matching engine
* Real-time order book
* Trade history
* Wallet connection
* Non-custodial architecture
* BTQ blockchain integration
* QUBX integration
* USDT integration
* Deposits and withdrawals
* On-chain settlement where technically feasible
* Transaction confirmation tracking
* Basic trading fee mechanism
* Order cancellation
* Failed/expired order handling
* Basic API/WebSocket support

Blockchain Architecture

BTQ is a Ravencoin-derived PoW blockchain using KawPoW.

The developer must evaluate the BTQ blockchain and determine the safest architecture for decentralized trading.

We are not looking for a generic EVM/AMM DEX.

We are interested in an order-book trading model, with potential approaches including:

* Decentralized order book + on-chain settlement
* P2P trading
* Atomic swap / HTLC-based settlement
* Other genuinely non-custodial solutions

The developer should recommend the most practical architecture after reviewing the BTQ blockchain.

Initial User Flow

BTQ / USDT

User connects wallet
→ views BTQ/USDT order book
→ places Buy/Sell order
→ orders are matched
→ settlement occurs
→ user receives the purchased asset

BTQ / QUBX

User connects wallet
→ views BTQ/QUBX order book
→ places Buy/Sell order
→ orders are matched
→ settlement occurs
→ user receives BTQ or QUBX

Non-Custodial Requirement

The platform must not take custody of user funds.

Users should control their own wallets/private keys and authorize transactions themselves.

The platform should not have an unrestricted ability to withdraw user assets.

Phase 1 — Technical Feasibility

Before full development, the developer should provide:

1. BTQ blockchain compatibility assessment
2. Recommended DEX/order-book architecture
3. Recommended settlement mechanism
4. Feasibility of BTQ/USDT atomic settlement
5. Feasibility of BTQ/QUBX settlement
6. Required BTQ blockchain modifications, if any
7. Open-source technology that can be reused
8. Estimated development timeline
9. Estimated development cost

Phase 2 — MVP

Develop a working platform supporting:

BTQ/USDT + BTQ/QUBX

with:

Wallet → Order Book → Order → Matching → Settlement → Trade History

The MVP should prioritize security, reliability and simplicity rather than a large number of features.

Preferred Experience

Strong preference for developers with experience in:

* DEX development
* CLOB/order-book exchanges
* P2P DEX
* Atomic swaps / HTLC
* Bitcoin/UTXO-based blockchains
* Ravencoin or Ravencoin-derived chains
* Blockchain RPC
* Wallet integration
* Decentralized settlement

Open-Source Approach

We prefer adapting proven open-source DEX/order-book infrastructure where the license permits, rather than building everything from scratch.

Developer should identify suitable existing projects and explain what modifications would be required for BTQ.

Partnership Opportunity

We are open to:

* Fixed-price development
* Milestone-based development
* Lower upfront cost + revenue share
* Technical partnership

Developers interested in becoming a long-term BitQube technical partner are welcome.

Proposal Requirements

Please provide:

* Previous DEX/order-book projects
* UTXO/Bitcoin/Ravencoin experience
* Proposed architecture
* Open-source frameworks you recommend
* BTQ integration approach
* USDT settlement approach
* Estimated timeline
* Development cost
* Security/audit approach
* Long-term maintenance cost
* Partnership/revenue-share proposal, if interested

Important: Please do not propose a generic PancakeSwap/Uniswap clone. The requirement is specifically for a non-custodial decentralized order-book trading engine supporting BTQ/USDT and BTQ/QUBX.
