# Aggregated Assets

**Aggregated assets** are unified token representation. Instead of managing USDC separately on Ethereum, Polygon, and Arbitrum, you work with a single identifier — e.g., mp:usdc — that represents all of your USDC holdings across supported chains.

Think of this as your **universal wallet view**: one asset ID that automatically abstracts away cross-chain complexity.

**How Aggregated Assets Work**

When you interact with an aggregated asset like mp:usdc, Mono Protocol automatically:

* **Aggregates balances** across every chain where you hold the token.
* **Optimizes routing** to use the most efficient chain for spending.
* **Bridges when needed** to complete cross-chain operations.
* **Unifies pricing** with consistent fiat value calculations.

**Supported Aggregated Assets**

Each aggregated asset includes:

* **Unique ID** (e.g., mp:<kbd><mark style="color:$success;">usdc<mark style="color:$success;"></kbd>, mp:<kbd><mark style="color:$success;">eth<mark style="color:$success;"></kbd>)
* **Symbol & Name** (human-readable identifiers)
* **Decimals** (precision for the asset)
* **Underlying assets** (the chain-specific tokens that make up the aggregate)

You can also:

* List supported assets — fetch all aggregated assets available.
* View underlying tokens — see which chain-specific assets compose them.

**Example: USDT Aggregated Asset**

```
{
  "aggregatedAssetId": "mp:usdt",
  "symbol": "USDT",
  "name": "Tether USD",
  "decimals": 6,
  "aggregatedEntities": [
    {
      "assetType": "eip155:1/erc20:0xdAC17F958D2ee523a2206206994597C13D831ec7",
      "decimals": 6,
      "name": "Tether USD",
      "symbol": "USDT"
    },
    {
      "assetType": "eip155:42161/erc20:0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9",
      "decimals": 6,
      "name": "Tether USD", 
      "symbol": "USDT"
    }
  ]
}
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://monoprotocol.gitbook.io/monoprotocol/advanced-concepts/aggregated-assets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
