# Blockchain & BNB Chain

> What a blockchain network is, why choosing the right one matters, and why GMRX uses BNB Chain.

A **blockchain network** is a digital system where cryptocurrencies and tokens live, move, and operate. Each network, such as Bitcoin, Ethereum, or BNB Chain, is its own separate environment with its own rules.

## Why the network matters

Because these networks are **not interchangeable**, choosing the correct one is essential.

<Warning>
  Sending crypto on the wrong network is like sending a letter to the wrong country: it may never arrive, and it usually cannot be recovered. This is why experienced users always send a **small test transaction first** to confirm the address, wallet, and network are all correct before transferring larger amounts.
</Warning>

## What is BNB Chain?

**BNB Chain** is the blockchain network used for GMRX. It is a fast, low-cost network that supports thousands of apps, tokens, and wallets.

When we say GMRX is "on BNB Chain," it means the token exists and operates on this specific network. This gives GMRX a secure home where it can be stored, traded, and used in any wallet or application that supports BNB Chain.

<Note>
  To hold or withdraw GMRX, set your wallet to the **BNB Chain** network. You can then [add the GMRX token →](/configure-gmrx) so your balance displays.
