# BM Scan: Public Block Explorer for the BM Chain L1

> BM Scan at bmscan.io is the public block explorer for BM Chain. Look up blocks, transactions, addresses, and contract interactions onchain.

**BM Scan** ([bmscan.io](https://bmscan.io/)) is the public, full-featured block explorer for BM Chain. Unlike Clob Scan — which lives inside BM.XYZ and is scoped to order book activity — BM Scan is an external site that exposes the complete L1 ledger. It is the canonical source of truth for anyone who wants to independently verify any transaction, balance, or contract interaction on BM Chain.

## What You Can Look Up

* **Blocks and block producers** — browse block height, timestamps, validator details, and included transactions
* **Transactions and internal transfers** — inspect any transaction hash, its status, gas usage, and value movements
* **Wallet addresses and token balances** — look up any address to see its current holdings and full transaction history
* **Contract interactions** — review decoded contract calls and indexed on-chain events as available

## How to Open from BM.XYZ

BM Scan is accessible directly from the BM.XYZ interface. In V2, use the top navigation **Explorer** dropdown and select **BM Scan** — this opens [bmscan.io](https://bmscan.io/) in a new tab.

## Clob Scan vs BM Scan

|              | Clob Scan                               | BM Scan                           |
| ------------ | --------------------------------------- | --------------------------------- |
| **Location** | Inside bm.xyz                           | External site at bmscan.io        |
| **Best for** | Order book trades and clearing activity | General L1 exploration            |
| **Audience** | Traders verifying fills                 | Developers, auditors, power users |

## Testnet vs Mainnet

BM Scan supports both testnet and mainnet. Before reading any data, confirm you are viewing the correct network — **network labels are displayed in the explorer header**. Testnet data is independent of mainnet; balances and transactions do not carry over between environments.

## Verifiable Fairness

BM.XYZ is built on the principle of **verifiable fairness**: every fill you see in the app corresponds to a real onchain record. Any trade executed on the order book should be traceable — first in Clob Scan for decoded trading detail, and independently in BM Scan against the full BM Chain ledger. This dual-layer transparency means you never have to take the exchange's word for it; the evidence is public and permanently recorded onchain.
