Frequently Asked Questions
Your most common questions about DEX development, answered.
The cost of a custom DEX varies significantly based on complexity, features, and the blockchain it's built on. A basic AMM-based DEX might start in the range of $50,000 - $100,000, while a complex cross-chain platform with advanced features and governance could exceed $500,000. We provide a detailed, transparent quote after our initial discovery and strategy session.
Similar to cost, the timeline depends on the project's scope. A Minimum Viable Product (MVP) can often be launched in 3-4 months. A full-featured, cross-chain DEX can take 6-12 months or more. Our agile process and modular architecture are designed to accelerate this timeline without compromising quality.
Security is our top priority. Our multi-pronged approach includes:
- Writing code based on industry best practices (e.g., Checks-Effects-Interactions pattern).
- Conducting multiple rounds of internal code reviews.
- Performing comprehensive unit and integration testing.
- Undergoing rigorous internal and third-party smart contract audits.
- Implementing real-time security monitoring post-launch.
Attracting initial liquidity is crucial. We help you implement several strategies:
- Liquidity Mining: Rewarding users with your native token for providing liquidity.
- Staking Programs: Offering attractive APYs for staking LP tokens.
- Partnerships: Collaborating with other projects to create initial pools.
- Initial DEX Offering (IDO): Launching your own token on your platform can bootstrap initial liquidity.
Absolutely. We strongly recommend Layer-2 integrations for most DEX projects to provide users with fast, low-cost transactions. We have extensive experience with leading L2s like Arbitrum, Optimism, Polygon, and zkSync.
Yes. Upon final payment and project completion, we transfer 100% of the intellectual property and source code to you. It is your platform, and you will have full ownership and control.
