# Block Explorer

> Inspect your first USDZ transfer

The Metal testnet block explorer shows transactions, account balances, and
blocks. Start with the transfer you sent
in [Make Your First Transfer](https://docs.metalntwx.com/start/make-your-first-transfer.md).

## What you can look up

* **Transactions** by hash: status, the gas paid in the MIP20 gas token, and the decoded call. For a `0x7f` MIP20 transaction the explorer shows the envelope fields, including which gas token paid.
* **Accounts** by address: MIP20 token balances and nonce. Balances are keyed by identity address.
* **Blocks**: height, millisecond-precision timestamp, and the included transactions.

Account history, token transfer history, and contract interaction history are
not available on testnet yet. These views show "History not available on this
network yet".

## Open your transaction

The previous guide saved your transaction hash as `TX_HASH`. Print its explorer
URL:

```bash theme={null}
echo "https://testnet.metalntwx.com/tx/$TX_HASH"
```

Open the printed URL. The transaction page should show:

* A successful status
* Your account as the sender
* The `*USDZ` contract as the transaction recipient
* A transfer of one `*USDZ` to your chosen recipient
* The transaction fee paid in `*USDZ`

The transaction recipient is the `*USDZ` contract because you called its
`transfer` function. The payment recipient appears in the decoded call and
transfer event.

## Inspect the sender and recipient

Print both account URLs:

```bash theme={null}
echo "Sender: https://testnet.metalntwx.com/address/$SENDER_ADDRESS"
echo "Recipient: https://testnet.metalntwx.com/address/$RECIPIENT_ADDRESS"
```

Open each URL to compare their token balances.

## Look up other activity

You can open any transaction, account, or block by replacing the value at the
end of these paths:

```text theme={null}
https://testnet.metalntwx.com/tx/<transaction-hash>
https://testnet.metalntwx.com/address/<address>
https://testnet.metalntwx.com/block/<block-number>
```

The SDK returns a transaction hash from `writeMip20Contract` and `sendMip20Call`.
The RPC method `eth_sendRawTransaction` also returns a hash, so you can link to
the transaction after broadcasting it.
