On-Chain Escrow Timeout Claim Tool

WHAT IT DOES

On-Chain Escrow Timeout Claim Tool connects to any EVM-based escrow contract and enables the intended recipient to claim locked funds after the timeout period has expired and release conditions remain unmet. The tool reads comprehensive contract state including locked funds amount, token address, depositor address, intended recipient address, release conditions and their fulfillment status, timeout/expiry timestamp, current block timestamp, dispute status, claim history, and grace period parameters. It then calculates the time remaining until timeout, displays a clear visual status indicator, and enables a one-click claim transaction when the timeout has expired. The tool handles multiple claim function signatures (claimTimeout, withdrawExpired, releaseAfterTimeout) and automatically detects the correct function to call. After submission, the tool displays the transaction hash and refreshes the contract data to show the updated state.

HOW TO USE

Connect your Web3 wallet (MetaMask, WalletConnect, or any EIP-1193 provider). Select the correct network for your escrow contract — the tool supports Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche C-Chain, and BNB Chain. Paste your escrow contract address into the input field. The tool reads the contract using a default ABI that covers standard escrow and timeout functions, but you can paste a custom ABI if your contract uses non-standard naming. Review the displayed data carefully: locked amount, token type, depositor and recipient addresses, timeout timestamp, current block timestamp, time remaining, grace period, conditions met status, and dispute status. The status indicator will show either "⏳ Pending" with the time remaining, "✅ Timeout expired — You can claim the funds!", "⚠️ Dispute active", or "✅ Conditions met — funds may be released by depositor". When the timeout has expired, conditions are not met, and no dispute is active, the "Claim timeout" button becomes enabled. Click it to submit the claim transaction — the tool will show a confirmation dialog with all details, submit the transaction, and wait for confirmation. After successful execution, the contract data refreshes automatically to show the funds as claimed.

THE REAL MECHANISM

This tool does not assume a single timeout logic — it adapts to the contract's actual implementation. It first detects the correct claim function by testing common names (claimTimeout, withdrawExpired, releaseAfterTimeout) through static calls, falling back to the user-provided name if none are found. For timeout calculation, the tool reads the timeout timestamp from the contract via timeout() and simultaneously fetches the current block timestamp using provider.getBlock('latest'). It then computes the time remaining in seconds and converts it to a human-readable format (days, hours, minutes). The tool also reads conditionsMet() to ensure that conditions are NOT met — if conditions are met, the depositor should release the funds normally rather than using the timeout claim. It reads disputeStatus() to block claims when a dispute is active. For contracts that implement a grace period, the tool reads gracePeriod() and displays it to provide full transparency. The status indicator updates in real-time, refreshing every 15 seconds to keep the time remaining accurate. All transaction parameters are estimated using eth_estimateGas and sent with the wallet's preferred gas strategy. The tool monitors the transaction receipt and extracts the effectiveGasPrice to display actual gas cost, not the cap. For native token escrows, the tool handles the transaction value automatically.

WHAT IT CANNOT SEE

On-Chain Escrow Timeout Claim Tool cannot verify that the timeout period is fair or reasonable for the specific agreement. It cannot detect off-chain communication attempts, informal extensions, or manual agreements between parties. It cannot determine if the depositor intended to extend the timeout but failed to update the contract. It cannot guarantee that the timeout logic is correctly implemented or free from bugs. It cannot prevent the depositor from releasing the funds before the timeout expires, even if you are waiting to claim. It cannot verify that the conditions were genuinely unmet rather than failing to evaluate correctly due to contract bugs, oracle failures, or other issues. It cannot recover funds if the claim transaction fails due to gas issues, network congestion, or contract reverts. It cannot detect if the depositor is trying to front-run your claim with a release transaction. It cannot ensure that the contract has not been upgraded or modified to change timeout behavior after your claim attempt.

PLEASE NOTE — EVM CHAINS ONLY

This tool works exclusively with EVM-compatible blockchains. Non-EVM chains are not supported. The tool does not deploy contracts, manage private keys, or sign anything outside the connected wallet's secure environment. It is a read-and-execute interface that relies entirely on the escrow contract's implementation and the timeout logic defined therein. Always verify the timeout timestamp and conditions directly on-chain before claiming.
