Submission Details
Severity:
getFee(LLMOracleTaskParameters) on LLMOracleManager contract is wrongly calculated
Summary
Fee is not calculated properly.
Vulnerability Details
Calculation of the getFee(LLMOracleTaskParameters) function is wrong because it does not calculate the fee so that every generation has to be validated. If there are 3 generations and 4 validators then the amount of validations is 12 (3*4 -> every generations is validated 4 times). As per sponsor explanation
Impact
Fee mechanism is erroneously calculated leading to a wrong calculation of totalFee.
Tools Used
Manual review
Recommendations
Rewrite getFee(LLMOracleTaskParameters) to following:
function getFee(LLMOracleTaskParameters calldata parameters)
public
view
returns (uint256 totalFee, uint256 generatorFee, uint256 validatorFee)
{
uint256 diff = (2 << uint256(parameters.difficulty));
generatorFee = diff * generationFee;
validatorFee = diff * validationFee;
totalFee = platformFee + (parameters.numGenerations * generatorFee) + (parameters.numGenerations * parameters.numValidations * validatorFee);
}
