Submission Details
Severity:
it is better to implement the while loop like this.
Summary
Implementing the while loop in this way can consume less gas
Vulnerability Details
for (uint256 i = 0; i < tokenAddresses.length; i++) {
s_priceFeeds[tokenAddresses[i]] = priceFeedAddresses[i];
s_collateralTokens.push(tokenAddresses[i]);
}
for (uint256 i = 0; i < s_collateralTokens.length; i++) {
address token = s_collateralTokens[i];
uint256 amount = s_collateralDeposited[user][token];
totalCollateralValueInUsd += getUsdValue(token, amount);
}
Impact

Recommendations
like this :
for (uint256 i = 0; i < tokenAddresses.length;) {
s_priceFeeds[tokenAddresses[i]] = priceFeedAddresses[i];
s_collateralTokens.push(tokenAddresses[i]);
unchecked {
++i;
}
}
for (uint256 i = 0; i < s_collateralTokens.length;) {
address token = s_collateralTokens[i];
uint256 amount = s_collateralDeposited[user][token];
totalCollateralValueInUsd += getUsdValue(token, amount);
unchecked {
++i;
}
}
