Vulnerability details

The public functions Auction.startAuction(), Auction.killAuction(), Auction.initialize(), Auction.bondForRebalance(), Auction.settleAuction() and Auction.addBounty() are never called by Auction. Therefore, their visibility can be reduced to external.

Impact

external functions are cheaper than public functions.

Proof of Concept

https://gus-tavo-guim.medium.com/public-vs-external-functions-in-solidity-b46bcf0ba3ac

Tool Used

Manual code review.

Recommended Mitigation Steps

Define these functions as public.
