Vault Auto-Withdrawal Scheduler

WHAT IT DOES

Vault Auto-Withdrawal Scheduler lets you schedule an automatic withdrawal from a DeFi vault at a future time (or block). Instead of manually withdrawing your funds at a specific time—which requires you to remember and execute the transaction—you set the withdrawal amount, destination address, and schedule time, and the vault handles the rest. The tool reads your vault balance, checks the vault's withdrawal parameters (delay, fees), and schedules the withdrawal using the vault's scheduling function. Once the scheduled time arrives, the withdrawal executes automatically (assuming the vault supports this mechanism). This is essential for DeFi users who want to automate their exits without manual intervention.

HOW TO USE

Connect your EVM wallet and select the network. Enter the vault contract address, the amount you want to withdraw, the destination address, and the schedule time as a Unix timestamp. Click "Check vault" to view your balance, the vault's withdrawal delay, fee, and any existing scheduled withdrawal. Review the details, then click "Schedule withdrawal" to execute the transaction. The tool calls the vault's scheduleWithdrawal() function, which records your withdrawal request for the specified time.

TECHNICAL MECHANISM

The tool first queries the vault contract for the user's balance using balanceOf(), the withdrawal delay using withdrawalDelay(), and the withdrawal fee using withdrawalFee(). It also checks for existing scheduled withdrawals via scheduledWithdrawals(). The scheduling is performed by calling the scheduleWithdrawal(address to, uint256 amount, uint256 timestamp) function on the vault contract. This function typically stores the withdrawal request in a mapping and emits an event. When the scheduled time arrives, the withdrawal can be executed by the user or by a keeper bot (depending on the vault's design). The tool uses receipt.effectiveGasPrice for accurate gas reporting and provides progress feedback during the scheduling process.

WHAT IT CANNOT SEE

This tool cannot schedule withdrawals if the vault does not support auto-withdrawal scheduling or if the user has insufficient balance—both conditions are verified before proceeding. It relies on the vault contract supporting the scheduling logic; vaults with non-standard scheduling mechanisms (e.g., requiring external keeper approval) are not supported. The tool cannot guarantee that the withdrawal will execute if the vault's state changes (e.g., strategy changes, paused withdrawals) or if gas conditions are unfavorable at the scheduled time. It also does not handle cancellation of scheduled withdrawals.

PLEASE NOTE

Scheduling a withdrawal does not guarantee execution—you may need to trigger the withdrawal manually or rely on a keeper bot depending on the vault's design. Ensure the schedule time is far enough in the future to account for any withdrawal delay enforced by the vault. The vault contract must be trusted; verify its security and audit status before use. This tool is for EVM chains only and does not support non-EVM networks.
