We have an Ethereum Smart Contract and a Learn To Earn program, and we're seeking an expert developer to review our contract and recommend the best approach for ensuring users pay the transaction costs when converting their earned points into our tokens. Our primary concerns are ensuring the security of the contract to prevent users from minting additional tokens and optimizing the transaction fee process.

Key Responsibilities:

    Contract Security Review: Conduct a thorough review of our Ethereum Smart Contract to identify and address potential vulnerabilities, specifically focusing on preventing unauthorized minting of tokens.
    Function Optimization: Recommend the ideal setup for public functions to ensure users can only convert their earned points without being able to mint extra tokens.
    Transaction Fee Management: Analyze our current use of 1Inch for processing transactions and propose a solution to effectively manage transaction fees. Since 1Inch does not support charging users a fee directly, we need a strategy to handle this, potentially involving users paying double transaction fees (one for their transaction and another for us).

Ideal Skills and Experience:

    Smart Contract Expertise: Extensive experience in developing and auditing Ethereum Smart Contracts, with a strong focus on security.
    Blockchain Transaction Knowledge: Deep understanding of blockchain transaction processes and fee management.
    1Inch Integration Experience: Proven experience with 1Inch or similar decentralized exchanges for transaction processing.
    Problem-Solving Skills: Ability to devise innovative solutions to complex problems, particularly regarding transaction fee management.

Deliverables:

    Comprehensive Contract Audit: A detailed report outlining any vulnerabilities found and recommendations for securing the contract.
    Function Setup Recommendation: Clear guidelines on how to set up public functions to ensure secure conversion of points to tokens.
    Transaction Fee Strategy: A practical solution for managing transaction fees effectively, minimizing the financial burden on users while ensuring the security and integrity of the transaction process.
