OpenBidder Contract

Overview

The OpenBidder contract facilitates participation in auctions by allowing users to place bids for gas space bundles. It interacts with other contracts such as WETH (Wrapped Ether), an auctioneer, and a settlement contract.

Features

• Bid Placement: Users can place bids for gas space bundles by specifying the amount of gas and the price per gas.
• Cancellation: Bidders can cancel their open bids and reclaim their funds.
• Bundle Submission: After an auction slot has ended, the contract automatically submits the bundle hashes to a settlement contract for processing.
