Dev Wallet Key Rotation Reminder

WHAT IT DOES

Dev Wallet Key Rotation Reminder helps you track and manage key rotation for development wallets. You provide wallet addresses, labels, and last rotation dates. The tool calculates the days since each wallet was last rotated, determines when it's due for rotation based on your configured interval, and displays a clear status: healthy, due soon, or expired. A summary dashboard shows total wallets, expired, due soon, and healthy counts. Each wallet displays its address, label, last rotation date, days until expiry, next rotation date, and a color-coded status badge. This is essential for teams managing multiple development wallets, ensuring security best practices are followed, and preventing the use of long-lived keys that could become compromised. The tool helps you stay on top of key rotation without relying on memory or manual spreadsheets.

HOW TO USE

Enter wallet details—one per line—in the format "address | label | lastRotation". For example: "0x123... | Deployer Wallet | 2024-01-15". The address must be a valid EVM address, and the date must be in YYYY-MM-DD format. Set your rotation interval in days (default 90 days) and a warning threshold (default 30 days before expiry). Click "Check Rotation Status." The tool calculates the current status for each wallet, sorts them by urgency (expired first, then due soon, then healthy), and displays the results. Use the summary to quickly see how many wallets need attention, and review each wallet's status to plan your rotation schedule.

THE REAL MECHANISM

The tool uses a pure JavaScript date calculation engine that operates entirely client-side. It parses each line, extracting the wallet address, label, and last rotation date. It validates the address format using a regular expression and validates the date by attempting to parse it. The tool calculates the number of days since the last rotation by comparing the last rotation date to today's date. It then calculates the days until expiry by subtracting the days since rotation from the configured rotation interval. Based on this value, it assigns a status: "critical" (expired), "warning" (within the warning threshold), or "healthy" (more than the warning threshold remaining). The next rotation date is calculated by adding the rotation interval to the last rotation date. All processing is done in the browser—no data is sent to external servers.

WHAT IT CANNOT SEE

This tool cannot automatically detect if a key has been compromised—it only tracks rotation dates. It cannot enforce key rotation without user action—it only reminds you. It cannot detect if keys are being used after expiration—you must check manually. It cannot generate rotation reminders for non-EVM wallets. It cannot verify the last rotation date without user input—it trusts what you provide. The tool does not read from the blockchain or check if a key has been used recently. It cannot detect if a wallet has been rotated but the date was not updated.

PLEASE NOTE

Dev Wallet Key Rotation Reminder works for any EVM wallet and does not require a blockchain connection to function, though the network selector is provided for context. It is a planning and tracking tool for developers, not an execution tool. It reads data only and does not send any information to external servers. The tool is free to use and does not require authentication. For best results, update last rotation dates whenever you rotate a key and review the status regularly.
