About this app
WHAT IT DOES
Pending Transaction Monitor lets you see all unconfirmed transactions sent from any wallet address on any EVM-compatible chain. Enter any address—yours or a counterparty's—and the tool scans the mempool and recent blocks to show every transaction that has been broadcast but not yet confirmed. For each pending transaction you get the hash, destination, value, nonce, and gas price. The tool automatically refreshes every 15 seconds so you can watch confirmations as they happen.
HOW TO USE
Connect your wallet using the injected bridge, then select the network you want to monitor. Enter the wallet address you want to track—the tool will also auto-fill your own connected address. Choose how far back to scan (5 to 100 blocks) and click "Find pending transactions". Results appear instantly with a pending status badge. Click any transaction hash to view it on the block explorer. The refresh button updates the list without re-entering the address. The tool runs entirely in your browser with no backend—your address never leaves your machine.
TECHNICAL MECHANISM
The tool queries the "pending" block directly via ethers.js getBlockWithTransactions("pending"), which returns all transactions currently in the mempool from the connected RPC provider. To catch pending transactions that some providers omit from the pending block, it also fetches recent confirmed blocks and cross-checks each transaction against its receipt—if no receipt exists, the transaction is still pending and gets included. All lookups use the wallet's own RPC connection, so the tool works with any provider your wallet uses, including private RPC endpoints. No API keys required.
WHAT IT CANNOT SEE
This tool only sees transactions from the specific address you enter—it does not monitor wallets you do not explicitly look up. It cannot predict exactly when a transaction will confirm, because confirmation time depends on network congestion, gas price, and validator behavior. It also cannot show transactions that have been replaced (same nonce, higher gas) unless they appear separately in the mempool. The tool reads the mempool through your wallet's RPC provider—if your provider does not expose full mempool data, some pending transactions may not appear.
PLEASE NOTE
EVM chains only. This tool reads chain state and builds no transactions—it never writes, spends, or signs anything. It is a read-only analytics tool. Requires a Web3 wallet (e.g., MetaMask) to connect.
