Hybrid DEX/CEX with Token Bridge
Budget: $750 – $1,500 USD
I’m ready to commission a full-stack hybrid exchange that blends a DEX and CEX under one roof, complete with on-chain bridging and wrapping so users can move assets seamlessly between Ethereum and Binance Smart Chain.
The core platform must provide:
• An order-book style trading interface that feels centralised but settles trades on-chain when users choose
• Native wallet integration (MetaMask, WalletConnect, etc.) for non-custodial interaction, while still supporting direct fiat deposits for newcomers
• Liquidity pooling contracts so users can earn fees and the exchange stays liquid
• Two-factor authentication for every account to keep security top of mind
Because bridging is central, I need robust smart contracts that lock, mint, and burn wrapped tokens with clear audit trails. The CEX layer should manage order matching and fiat rails, yet always let users withdraw on-chain whenever they wish. Think along the lines of Solidity for the contracts, a Node/TypeScript or Go back-end, and a React front-end, but I’m open to your proven stack if it meets the same standards.
Deliverables — all handed over before final payment:
1. Smart contracts (DEX, bridge, liquidity pools) fully tested on Ethereum & BSC mainnets
2. Backend services for order matching, KYC/AML hooks, and 2FA
3. Front-end UI/UX that mirrors leading exchanges in speed and clarity
4. Deployment scripts, CI/CD pipeline, and a short run-book for future upgrades
5. Post-launch support for bug fixes during an agreed warranty window
The fixed budget is $2,000, so I’m looking for someone who already has deep, reusable experience with hybrid exchanges to keep the build efficient. Share links or repos that prove you’ve shipped similar products, outline your timeline, and highlight any previous audits or security reviews you’ve passed.
If you can deliver a secure, audited, and user-friendly hybrid DEX/CEX within scope, let’s get started.
