Summary

we are comparing the "params.amount == 0x0" but it should be compared to 0.

/**
* @dev points and amount must be greater than 0
* @dev eachTradeTax must be less than 100%, decimal scaler is 10000
* @dev collateralRate must be more than 100%, decimal scaler is 10000
*/
i@>>f (params.points == 0x0 || params.amount == 0x0) {
revert Errors.AmountIsZero();
}
