# Variable Cap Asset

### 1. Write the token smart contract

{% embed url="<https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol>" %}

{% hint style="info" %}
This contract is designed to be unopinionated, allowing developers to access the internal functions in ERC20 (such as \_mint) and expose them as external functions in the way they prefer. On the other hand, ERC20 Presets (such as ERC20PresetMinterPauser) are designed using opinionated patterns to provide developers with ready to use, deployable contracts.
{% endhint %}

#### Functions

* name()
* symbol()
* decimals()
* totalSupply()
* balanceOf(account)
* transfer(recipient, amount)
* allowance(owner, spender)
* approve(spender, amount)
* transferFrom(sender, recipient, amount)
* increaseAllowance(spender, addedValue)
* decreaseAllowance(spender, subtractedValue)
* \_transfer(sender, recipient, amount)
* \_mint(account, amount)
* \_burn(account, amount)
* \_approve(owner, spender, amount)
* \_setupDecimals(decimals\_)

### 2. Compile your code into bytecode

### 3. Deploy your Variable-cap Asset by sending your code in a transaction to the Enter network

### 4. Navigate to the explorer to check that your token has been created

### 5. **You can use the \_mint function to create additional units of the token**
