# Decode block explorer transactions

WalletChan can add its transaction-details view to supported block explorer
`/tx/<hash>` pages. This works for the explorers configured for WalletChan's
active built-in and custom EVM networks, including Etherscan and BaseScan.

## Switch between explorer and WalletChan details

On a supported transaction page, WalletChan adds two tabs to the explorer's
**Input Data** section:

* The explorer tab preserves the site's original input-data display and tools.
* **WalletChan** is selected by default and shows a compact, left-aligned
  transaction view inside that section.

WalletChan resolves the transaction hash from the page URL and uses the RPC
configured for that explorer's chain. It checks the RPC chain and returned
transaction before displaying anything.

## What WalletChan shows

* A plain-language action and verified clear-signing fields when available.
* Decoded and raw calldata, expanded by default for technical verification.
* Human-readable inner calls for ERC-7821 batch transactions instead of only
  showing the outer `execute` wrapper.
* Contract, token, address, and amount labels when public metadata resolves.

The explorer view is read-only. It cannot access wallet accounts, history,
credentials, pending requests, signing, or transaction submission.

## Turn explorer enhancements off

Open **Settings → Enhance Block Explorers** and disable **WalletChan transaction
details**. WalletChan immediately removes an existing injected view and stops
explorer resolution, iframe creation, and transaction RPC work until the
setting is enabled again.

The preference is on by default and syncs with your extension settings.
