Surplus Auction House

For more details, refer to the SurplusAuctionHouse.sol contract.

1. Introduction

The Surplus Auction House is tasked with auctioning the system's surplus coins in exchange for protocol tokens. A fraction of these protocol tokens is burnt to create a deflationary effect, while the rest is transferred to a specified target address. The auction employs an ascending bidding model: a fixed number of system coins are up for auction, and participants bid by offering increasingly higher amounts of protocol tokens.
