# Asset basics

This lesson covers the core ideas behind FT4 assets and how they work on Chromia.

## What are FT4 assets?

An FT4 asset is a digital token that stands for anything of value on the Chromia blockchain. You create these tokens with the FT4 library, which gives you a standard way to define and manage them.

## Key components of FT4 assets

**Account management**

* Pool accounts that manage assets
* User accounts that hold assets
* Multiple account types, each with its own permissions

**Asset registration**

* You must register each asset on the blockchain
* Each asset gets a unique identifier
* Properties such as name, symbol, and number of decimal places describe an asset

**Asset operations**

* Minting: creates new units of an asset
* Burning: destroys existing units
* Transferring: moves units from one account to another
* Locking: blocks an asset from moving for a period of time

## Account types of the dapp

The project relies on two main kinds of account:

**Pool account**

* Handles the initial distribution of the asset
* Controlled by the dapp

**User accounts**

* Users create these themselves
* Hold assets and send them to other accounts

Permissions on an FT4 account depend on what the account is for. To keep things simple, this project uses only two roles: `user` and `admin`.

## Asset registration

Next, you set up a basic asset configuration and register the asset.

Put the following code in `src/main/module.rell`:

src/main/module.rell

```
import lib.ft4.assets.{ asset, Unsafe };
import lib.ft4.core.accounts.strategies.open;

// Asset properties
val account_type = "PoolAccount";
val asset_name = "TestAsset";
val asset_symbol = "TAT";
val asset_decimals = 6;
val asset_icon_url = "https://url-to-asset-icon";
val asset_amount_to_mint = 1000000000L;
val asset_amount_to_faucet = 100000L;
val asset_amount_to_burn = 100L;

object dapp_meta {
    asset = Unsafe.register_asset(
        asset_name,
        asset_symbol,
        asset_decimals,
        chain_context.blockchain_rid,
        asset_icon_url
    );
}
```

This code sets the asset's configuration and registers the asset when the blockchain initializes.

The next lesson adds operations for minting, burning, and transferring the asset.
