# Add Metaverse Smart Tokens (MST) in MetaverseVM Browser wallet

## Introduction

Metaverse Smart Tokens are tokens, which follow a given list of standards and rules (e.g. transfer, transaction approval, token supply, data access, etc.).  

MSTs currently exist in **two different forms**: **MRC-20 MSTs** and **UTXO MSTs**. MRC-20 tokens exist in the MetaverseVM while UTXO MSTs exist on the UTXO Chain and can be accessed via MyETP Wallet. MRC-20 tokens and UTXO MSTs exist on two different ledgers. As a result, an asset issued on the UTXO chain will not appear on the MetaverseVM.

Metaverse technical team is working towards a solution to transfer UTXO MSTs to the Metaverse VM as MRC-20 tokens. Once a solution is found, we will advise the Metaverse community on how to proceed with the migration of UTXO MSTs to the new ledger.  

In the following guide, we introduce how to add MRC-20 tokens to the MetaverseVM Browser wallet. 

## Tutorial
