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.
- 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.
Functional scripts have been provided for full interaction with OpenBidder.
