✋ Hello! We are the IT company dZENcode.

We implement Solidity smart contracts for Arbitrum: GMX architecture, USDT liquidity pools, TP/SL, HardStop, logging, and preparation for copy trading and grid trading, based on the team's experience, best practices, and our own developments.

What version of GMX is the solution based on — v1 or v2?
Is there current code for the contracts and tests/audit?

You can find detailed information about our services and rates on our website: Freelancehunt.

Hello, Natalia

I like your project, I have worked with Dex protocols and I know how to create a flexible, modular, and scalable architecture for your business idea.

Please be sure to contact me privately.

Good day
Experience working with Solidity - 8 years. I am in 1st place in the blockchain category on this site. I have worked with almost all DeFi protocols in EVM networks. I also constantly work with Python when writing web3 applications. I conduct testing using Foundry. I will take on the implementation and making adjustments. It is necessary to see the source code of what already exists to understand the scope of work and form the final bid.

Regarding the improvements of smart contracts, you have quite a complex task. This involves not only modifying the existing code but also implementing new mechanisms, such as an emergency stop button or a liquidity pool on USDT. I have experience working with DeFi protocols, including similar projects, and I will be able to handle all the requirements. I also have experience with Hardhat and an understanding of the GMX architecture, so I can quickly adapt to your code. Given the complexity and scope of the work, I propose an amount starting from 10,000 UAH. The implementation will take approximately 10 days, considering buffer time for testing and refinement.
