# XVS

## XVS

XVS contract serves as a customized ERC-20 token with additional minting and burning functionality. It also incorporates access control features provided by the "TokenController" contract to ensure proper governance and restrictions on minting and burning operations.

## Solidity API

#### mint

Creates `amount_` tokens and assigns them to `account_`, increasing the total supply. Checks access and eligibility.

```solidity
function mint(address account_, uint256 amount_) external
```

**Parameters**

| Name      | Type    | Description                           |
| --------- | ------- | ------------------------------------- |
| account\_ | address | Address to which tokens are assigned. |
| amount\_  | uint256 | Amount of tokens to be assigned.      |

**📅 Events**

* Emits MintLimitDecreased with new available limit.

**⛔️ Access Requirements**

* Controlled by AccessControlManager.

**❌ Errors**

* MintLimitExceed is thrown when minting amount exceeds the maximum cap.

***

#### burn

Destroys `amount_` tokens from `account_`, reducing the total supply. Checks access and eligibility.

```solidity
function burn(address account_, uint256 amount_) external
```

**Parameters**

| Name      | Type    | Description                             |
| --------- | ------- | --------------------------------------- |
| account\_ | address | Address from which tokens be destroyed. |
| amount\_  | uint256 | Amount of tokens to be destroyed.       |

**📅 Events**

* Emits MintLimitIncreased with new available limit.

**⛔️ Access Requirements**

* Controlled by AccessControlManager.

## 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://docs-v4.venus.io/technical-reference/reference-xvs-bridge/xvs.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.
