Order Flow Auction Bid Submitter

WHAT IT DOES

The Order Flow Auction Bid Submitter enables users to submit bids in order flow auctions. It reads order flow auction contract state, user address, wallet balance, and bid parameters including amount and deadline. The tool processes order flow data, auction state, current bid, auction end time, and minimum bid increment. It supports submitBid for single bid submission, batchSubmitBids for multiple bids in one transaction, and submitWithProof for proof-based bid submission. The tool reads gas price, base fee, block timestamp, chain ID, transaction nonce, approval state, contract owner state, and bidder status before execution.

HOW TO USE

Connect your wallet and select the target network. Enter the auction contract address and the auction ID. Specify your bid amount in native tokens (e.g., ETH) and optionally set a bid deadline in seconds from now. For proof-based submission, enter proof data as hex. Choose the execution method (submitBid, batchSubmitBids, or submitWithProof). The tool will fetch auction state, display the current highest bid, auction end time, and minimum bid increment. Once confirmed, it submits your bid. The tool checks your bidder status and warns if you already have an active bid.

TECHNICAL MECHANISM

Unlike generic bid submission tools, this executor is purpose-built for order flow auctions. It first reads the auction contract's getAuction() to fetch the current highest bid, end time, minimum bid increment, and highest bidder. The tool checks isActive() to ensure the auction is still accepting bids. It reads the bidder's status via getBidderStatus() to display existing bids. The tool validates the bid amount against the current highest bid and minimum increment, and checks the deadline to ensure the bid will be valid. It selects the optimal method: submitBid for standard bids, batchSubmitBids for multiple auctions in one transaction, or submitWithProof for proof-based eligibility when the auction requires verification. The deadline is computed as current timestamp + user-specified duration. Gas costs are calculated using receipt.effectiveGasPrice for accurate post-EIP-1559 fee accounting.

WHAT IT CANNOT SEE

This tool cannot guarantee that the bid will win the auction or that the order flow will be executed as expected. It cannot predict the exact gas price required for inclusion, nor can it detect if other bidders are submitting higher bids. It also cannot guarantee that the auction will settle successfully. The tool cannot detect if the auction has been front-run or if the order flow data is valid. It also cannot verify that the proof data correctly establishes eligibility.

PLEASE NOTE

This tool supports EVM-compatible chains. Submitting a bid is binding—verify the auction state and bid amount before signing. The bid deadline must be later than the current block timestamp; setting it too short may cause the bid to expire before inclusion. Batch bids require the same number of auction IDs, amounts, and deadlines. For proof-based bids, ensure proof data is generated off-chain. This tool does not settle auctions—for that, use the Auction Settlement Tool.
