Block-Height-Triggered Executor

WHAT IT DOES

This tool evaluates block-height-triggered executors, helping developers and users monitor transactions that are scheduled to execute at specific block heights. Given a trigger contract address, a trigger ID, and an optional user address, it reads the trigger details—target address, call data, value, target block height, and execution status. It also retrieves the current block number, calculates the remaining blocks until the target, and checks if the trigger can be executed. The tool then determines the trigger status—Ready to execute, Executed, Pending (waiting for target block), or Blocked (conditions not met)—and displays a visual block progress bar showing the current block relative to the target. All data is pulled directly from the blockchain in real time, providing a transparent, comprehensive view of block-height-triggered execution readiness.

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 block-height trigger contract address and the trigger ID to check. Optionally, provide a user address (defaults to connected wallet). Click "Check trigger." The tool will fetch the trigger details, current block number, execution status, and execution readiness. Results appear in the card below with a prominent trigger status badge, a visual block progress bar showing current block versus target block, trigger details including target address, value, target block, and executed status, and a detailed breakdown of execution readiness factors (target block reached, not executed, canExecute true). Use this information to monitor block-height-triggered transactions and identify when they are ready for execution.

BLOCK-HEIGHT-TRIGGERED EXECUTION VERIFICATION WITH PROGRESS TRACKING

The tool provides comprehensive block-height-triggered execution verification through multiple on-chain reads. First, it calls getTrigger() to retrieve the trigger details—target address, call data, value, target block height, and executed status. It then calls getBlockNumber() on the provider to get the current block height, and calculates the remaining blocks until the target is reached. The canExecute() function checks all conditions—target block reached, not executed, and any contract-specific conditions. The tool also retrieves the total trigger count via getTriggerCount() for context. The block progress is displayed as a visual bar showing the current block relative to the target, with color coding—amber for approaching and teal for reached. The blocks remaining count is displayed prominently. All factors are combined to provide a clear, actionable view of block-height-triggered execution readiness with detailed progress tracking.

WHAT IT CANNOT SEE

This tool cannot guarantee execution at the exact block height—chain reorganizations may cause blocks to be re-ordered or removed. It cannot predict chain reorganization or ensure that the trigger will execute at the intended block. It cannot verify off-chain trigger conditions or ensure that the call data is correct. It cannot ensure execution success or detect if the execution transaction fails. It cannot detect block manipulation risks, including reorgs or other chain-level attacks. It cannot assure that the trigger contract is free from vulnerabilities, bugs, or malicious code. It cannot verify that the target address is correct or that the call data is valid. It cannot detect errors in the target block calculation or ensure that the block height is correctly reached. It cannot provide financial advice or guarantee that executing the trigger is safe. All data is provided as-is for informational purposes only; any reliance on the tool's output for trigger execution 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, trigger IDs, or execution 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. Block height calculations are based on the current chain state and do not guarantee execution at a future block. Always verify critical data independently through a block explorer and consult with security professionals before executing any block-triggered transactions.
