WETH Non-Collateral Flash Minting Development

I'm in need of a developer to create a non-collateral flash minting solution for Wrapped Ether (WETH). This system will utilize time locks for transactions, enabling a specific amount of WETH transactions and allowing multiple arbitrage opportunities before the final payment is executed. I'm working with a tight budget but can offer 20% of the funds to the developer in Bitcoin on deployment, in exchange for a lower price for development and testing. Additionally, 1% of the flash minted tokens will be allocated to the project in Bitcoin to lower the initial costs. The project deadline is February 10, 2025.

Key Requirements:
- Time locks for transactions
- Facilitating multiple arbitrage opportunities
- Executing the final payment

Security:
- Basic security measures are required, without the need for formal verification and third-party audits.

Technical Compatibility:
- The solution must be compatible with the Ethereum network.

Ideal Skills and Experience:
- Proficiency in Ethereum and smart contract development
- Previous experience with flash minting solutions
- Understanding of arbitrage opportunities in crypto transactions
- Basic security implementation for blockchain projects.
