Smart Contract Development for Arbitrage Strategy

DeFi Smart Contract Developer Needed — Short-Term Borrowing & Arbitrage

I’m looking for an experienced Solidity/DeFi developer to build a smart contract that will allow me to access borrowed capital for a specific arbitrage strategy.

The goal is to use the borrowed funds for one specific arbitrage operation, with the funds potentially needing to remain available for several hours before being returned. I’m therefore looking for someone who understands the difference between a conventional flash loan, which typically requires repayment within the same transaction, and other short-term borrowing/financing structures that could support a longer timeframe.

I need the developer to:

Design and develop the smart contract from scratch.
Identify a technically feasible way to obtain the required temporary capital.
Allow the capital to be used for the intended arbitrage strategy.
Handle repayment according to the requirements of the lending/financing mechanism.
Ensure the contract is properly tested and secured before deployment.
Explain any collateral, fees, repayment requirements, or other conditions involved.

Budget: $750+

I need the borrowing period to be no more than 18 hours. I’m open to increasing the budget if additional development is necessary for a viable solution.

I’m also open to alternative approaches to a traditional flash loan if there is another legitimate way to obtain temporary capital for this strategy.

Please do not simply tell me that a conventional flash loan cannot remain outstanding for several hours. I’m specifically looking for a developer who can evaluate alternative DeFi lending or short-term financing mechanisms and recommend a workable architecture.

Please provide examples of relevant Solidity, DeFi lending, flash-loan, or arbitrage projects you have worked on.
