# Assets

> Define the currencies, cryptocurrencies, and tokenized instruments your Accounts hold — multi-asset support across a single Ledger.

Assets represent the financial instruments or currencies that Accounts hold. Each Account holds exactly one Asset.

Assets can include:

* Currencies (e.g., BRL, USD, EUR)
* Cryptocurrencies (e.g., BTC, ETH)
* Non-currency assets (e.g., gold, loyalty points, tokenized securities)

Midaz keeps each Asset independent within the Ledger. Balances stay clearly defined.

### Multi-Asset

Finance today spans more than one currency or asset class. Midaz supports traditional currencies, cryptocurrencies, commodities, and tokenized assets in one system. Use it for multi-currency wallets, cross-border payments, or digital asset portfolios.

## Asset structure

***

* **Asset > Account**: Each Account holds a single Asset.
* **Asset > Ledger > Account**: You define Assets at the Ledger level. You create Accounts from the available Assets.

## Key characteristics

***

* You must define each Asset before you use it.
* Each Asset has a unique identifier, such as a currency code.
* To convert value between Assets, Midaz uses asset rates.

<Note>
  When you create an Asset, Midaz automatically creates an [External Account](/en/midaz/accounts) if one does not exist. The External Account backs every transaction that enters or leaves the Ledger.

  The External Account uses the naming convention `@external/<asset-code>`, for example, `@external/BRL`.
</Note>

## Managing Assets

***

You can manage Assets through the API or the Lerian Console.

### Via API

* [List Assets](/en/reference/midaz/list-assets) — View all Assets in your workspace.
* [Retrieve an Asset](/en/reference/midaz/retrieve-an-asset) — Get details of a specific Asset.
* [Create an Asset](/en/reference/midaz/create-an-asset) — Register a new Asset in the Ledger.
* [Update an Asset](/en/reference/midaz/update-an-asset) — Edit the properties of an existing Asset.
* [Delete an Asset](/en/reference/midaz/delete-an-asset) — Mark an Asset as deleted so it can no longer be used.

<Danger>
  **Important**

  When you delete an Asset, Midaz also deletes its External Account. The delete does not move or clear the balances that Accounts still hold in the Asset. Transfer those balances to an External Account before you delete the Asset.
</Danger>

### Via Lerian Console

You can view, create, edit, and delete Assets on the Assets page in the Midaz module of the Lerian Console.
