Wormhole Transfer Tracker

WHAT IT DOES

The Wormhole Transfer Tracker is a read-only tool that lets you monitor Wormhole cross-chain transfers. Enter a source transaction hash and the Wormhole core bridge contract address, and the app fetches the transaction and receipt from the source chain. It then displays the source transaction status, from/to addresses, token symbol and amount, Wormhole fee, destination chain information, redemption status, block number, and a count of Wormhole-specific events found. The tool analyzes transaction logs to detect Wormhole's standard events — LogMessagePublished and TransferWithPayload — as well as standard Transfer events. This gives you a comprehensive view of your Wormhole transfer from the source chain to the destination chain. This is useful for users tracking their Wormhole transfers, developers debugging cross-chain flows, and auditors verifying Wormhole transactions.

HOW TO USE

1. Select your source network from the dropdown or connect your wallet to use its RPC endpoint.

2. Enter the source transaction hash (the transaction on the source chain that initiated the Wormhole transfer).

3. Enter the Wormhole core bridge contract address on the source chain (e.g., 0x98f3c9e6E3fAce36bAAd05FE09d375Ef1464288B on Ethereum).

4. Click "Track transfer" to fetch and display the Wormhole transfer details.

5. Review the details: source status, source chain, from/to addresses, token symbol, amount, Wormhole fee, destination chain, redemption status, block number, and count of Wormhole events found.

6. Use the "Clear" button to reset all fields and start a new tracking session.

ONE TECHNICAL SECTION

This tool uses ethers v5's provider.getTransaction() and provider.getTransactionReceipt() methods to fetch the source transaction and its receipt. It then analyzes the receipt logs to detect Wormhole-specific events. The tool looks for LogMessagePublished (emitted when a message is published to the Wormhole network) using its signature hash, and TransferWithPayload (emitted for token transfers with additional payload data). It also detects standard Transfer events to identify the token being bridged and the amount. The tool counts Wormhole events found and provides a heuristic redemption status — if a TransferWithPayload event is found, it suggests the transfer has been initiated on the destination side; otherwise, it indicates the transfer is awaiting redemption. This event-based approach allows the tool to work with the standard Wormhole interface across different EVM chains without requiring per-chain configuration.

WHAT IT CANNOT SEE

This tool cannot track Wormhole transfers that use private relays or off-chain settlement beyond VAA (Verifiable Action Approval) data — if the VAA is not redeemed on-chain, the tool cannot show the destination transaction. It cannot view transfers that have not been attested or redeemed on-chain; the attestation and redemption steps are critical to the Wormhole workflow and may happen off-chain or on a different chain. The tool is limited by RPC availability and event query limits on each chain — if the source chain's RPC does not provide full logs, some data may be missing. It cannot track non-EVM chains, even though Wormhole supports them, because the tool cannot query those chains. It cannot predict VAA processing times or final settlement delays, which
