New Contract Deployment Alert for Watched Deployer

WHAT IT DOES

This tool connects to your EVM wallet and monitors for new contract deployments from watched deployer addresses. It reads transaction logs and contract creation events to detect when a watched address deploys a new contract. The tool fetches the deployed contract address, creation transaction hash, block number, gas usage, and timestamp. It provides a clear summary of all new deployments found, helping you track activity from specific deployers across EVM chains.

HOW TO USE

Connect your Web3 wallet using the Connect button. Enter the deployer address you want to watch in the Deployer Address field. Specify the block range to scan (default 10,000 blocks). Enter an optional deployer name for display purposes. Click "Check Deployments" to scan for new contract deployments. Click "Load Sample" to populate fields with an example address. Results appear in the Results card with a summary of deployments found and a detailed list of each deployment showing the contract address, transaction hash, block number, gas used, and timestamp.

TECHNICAL MECHANISM: DEPLOYMENT DETECTION VIA BLOCK SCANNING

The tool uses ethers.js to scan blocks for transactions from the watched deployer address. It iterates through blocks in the specified range, retrieving each block with transactions using provider.getBlockWithTransactions(). For each transaction from the deployer address, it checks if the transaction is a contract creation by verifying that the 'to' field is null or the zero address. If a contract creation is detected, the tool fetches the transaction receipt to obtain the deployed contract address. Each deployment is recorded with its transaction hash, contract address, block number, gas usage, and timestamp. The tool caps results at 50 deployments for performance and displays them in reverse chronological order.

WHAT IT CANNOT SEE

This tool cannot send notifications without active monitoring or push infrastructure—it displays data on-demand but does not send alerts. It cannot detect deployments that occur through factory contracts or proxies without additional logic—only direct deployments from the watched address are detected. It cannot distinguish between legitimate deployments and malicious activity without context—the tool provides data but not analysis. It relies on transaction history availability and may miss deployments that occurred before monitoring started—deployments are only detected within the scanned block range. It cannot track deployments on chains not actively monitored—the tool only scans the currently selected network.

PLEASE NOTE

This is a read-only tool—it never signs transactions. All data is fetched on-demand and stored only in memory; nothing is persisted across page reloads. The tool supports EVM chains only—Ethereum, Polygon, BSC, Arbitrum, Optimism, Avalanche, Base, and Fantom. Large block ranges may take time to scan—consider using smaller ranges for faster results. The tool does not send push notifications—it is designed for manual monitoring and review. Deployments through proxies or factory contracts may not be detected—the tool only detects direct contract creations.
