Recurring On-Chain Payment Scheduler

WHAT IT DOES

This tool evaluates recurring on-chain payment schedules, helping users track and manage automated payment streams. Given a scheduler contract address, a user address, and an optional schedule ID, it reads all active and historical schedules for the user, including recipient address, token address, payment amount, interval, next payment date, expiry, and active status. It also retrieves payment history, total paid amount, and schedule count. Each schedule is displayed with its current status—Active, Payment pending, Expired, or Inactive—along with a countdown to the next payment. All data is pulled directly from the blockchain in real time, providing a transparent, comprehensive view of recurring payment obligations.

HOW TO USE

Connect your wallet using the Connect button in the header, or enter a user address manually. Select the target network from the dropdown—Ethereum Mainnet, Polygon, Optimism, Arbitrum One, Base, or Sepolia testnet. Enter the recurring payment scheduler contract address. Optionally, provide a user address (defaults to connected wallet) and a schedule ID to view a specific schedule. Click "Check schedule." The tool will fetch all schedules for the user, or a specific schedule if an ID is provided. Results appear in the card below with a schedule card for each payment plan showing the recipient, token, amount, interval, next payment date, expiry, active status, total paid, and payment count. Use this information to monitor and manage recurring on-chain payments.

RECURRING PAYMENT SCHEDULE VERIFICATION WITH STATUS AND HISTORY ANALYSIS

The tool provides comprehensive recurring payment schedule verification through multiple on-chain reads. First, it calls getScheduleCount() to determine the total number of schedules for the user, then iterates through them using getSchedule() to retrieve each schedule's details—ID, recipient, token, amount, interval, next payment timestamp, expiry, and active status. If a schedule ID is provided, it calls getScheduleById() for that specific schedule. The tool also retrieves payment history via getPaymentHistory() and total paid amount via getTotalPaid() for detailed tracking. Each schedule's status is determined by comparing the current timestamp against the next payment date and expiry—Active (future payments scheduled), Payment pending (next payment due), Expired (past expiry), or Inactive. The interval is displayed in days and hours for easy readability. All factors are combined to provide a clear, actionable view of recurring payment schedules with detailed status indicators and payment history.

WHAT IT CANNOT SEE

This tool cannot guarantee payment execution—on-chain conditions may change between the check and the scheduled payment. It cannot predict future balance changes or ensure that the user will have sufficient funds at the time of payment. It cannot verify off-chain payment conditions or ensure that the recipient is still valid. It cannot ensure recipient solvency or detect changes in recipient status. It cannot detect schedule manipulation risks, including front-running, MEV, or other attacks. It cannot assure that the scheduler contract is free from vulnerabilities, bugs, or malicious code. It cannot verify that the token address is correct or that the recipient address is valid. It cannot detect errors in the payment calculation or ensure that the amount is accurate. It cannot provide financial advice or guarantee that managing recurring payments is safe. All data is provided as-is for informational purposes only; any reliance on the tool's output for payment decisions is the sole responsibility of the user.

PLEASE NOTE

This tool supports EVM-compatible chains only: Ethereum Mainnet (1), Polygon (137), Optimism (10), Arbitrum One (42161), Base (8453), and Sepolia testnet (11155111). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool requires a Web3 provider (MetaMask or WalletConnect) and access to an RPC endpoint for the selected chain. It does not store any wallet data, schedule IDs, or payment records. All queries are performed directly against the blockchain in real time. The tool only provides read-only information and does not execute any transactions. Payment schedules and amounts are contract-defined values and do not guarantee payment execution. Always verify critical data independently through a block explorer and consult with financial advisors before making any payment scheduling decisions.
