Dutch Auction Settlement Claimer

WHAT IT DOES

Dutch Auction Settlement Claimer is a non-custodial tool that claims settlements after a Dutch auction concludes, completing the auction lifecycle by delivering assets or processing refunds. It reads Dutch auction settlement contract state, user address, token balances, auction parameters, auction ID, token ID, winning bid amount, settlement status, claim eligibility, claim deadline, user's claim history, asset delivery status, collateral return state, settlement window, and claim fee structure to structure the optimal settlement claim operation. With a single transaction, it calls claimAuctionSettlement(), executeSettlementClaim(), or submitSettlementClaim() on the target contract, receiving assets if the user won the auction or claiming a refund if they did not. The tool handles both winning and losing scenarios, ensuring users complete the auction lifecycle.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the Dutch auction settlement contract address.

3. Enter the auction ID and optional token ID.

4. Optionally specify a claim fee (if required by the contract).

5. Review the settlement status, winning bid amount, claim eligibility, claim deadline, and asset delivery status.

6. Click "claim settlement" and confirm the transaction in your wallet.

The tool checks settlement status, claim eligibility, and claim deadline before execution to prevent failed transactions. After the transaction confirms, your settlement is claimed—no centralized custody, no intermediaries. Winning bidders receive the auction asset, while losing bidders receive refunds of their collateral.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH ELIGIBILITY VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts claimAuctionSettlement(), then falls back to executeSettlementClaim() or submitSettlementClaim() if the primary method fails—automatically adapting to different contract implementations without requiring the user to know the exact function name. For all on-chain reads, it uses chunked block range scanning that halves on failure, preventing the common "eth_getLogs limit exceeded" error that halts most scanners on public RPCs. It double-verifies settlement eligibility by checking both the current settlement status and claim deadline from storage, rather than relying on historical events—because an event log proves a bid was placed, not that the settlement can currently be claimed. Gas estimation uses receipt.effectiveGasPrice for accurate post-EIP-1559 cost accounting, and all batched operations are sequential with concurrency caps to avoid nonce conflicts. The tool also validates that the auction has finalized and that the claim deadline has not passed before execution.

WHAT IT CANNOT SEE

This tool cannot verify that the Dutch auction contract is legitimate or has not been compromised. It cannot detect if the auction has been manipulated. It cannot ensure that settlement will execute at the optimal gas price due to network conditions. It cannot guarantee that settlement will succeed if the auction contract is paused or frozen. It cannot verify that the contract has not been upgraded or modified. It cannot detect if the trade path is optimal or not front-run. It cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that the settlement amount is correct or not. It cannot predict market movements, price gaps, or flash crashes. It cannot guarantee execution during extreme network congestion or volatile market conditions. It cannot detect if the underlying asset has been compromised. It cannot prevent the user from canceling or modifying settlement parameters. It cannot ensure that the auction has finalized correctly. It cannot protect against loss if settlement is processed incorrectly. It cannot verify that the position is eligible for settlement. It cannot guarantee that assets will be delivered. It cannot ensure that refunds will be processed correctly. It cannot verify that the claim deadline has not passed.

PLEASE NOTE

This tool operates only on EVM-compatible chains (Ethereum Mainnet, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses, auction IDs, and settlement parameters before executing. Settlement claims are subject to claim deadlines—claims must be made within the settlement window. The tool is provided as-is; use at your own risk.
