# L2 Vault

The `Vault` is a simple smart contract designed to enable the DAO to manage chain-native assets and ERC-20 tokens across chains other than Ethereum.

:::vyper[`Vault.vy`]

The source code of the `Vault.vy` contract can be found on [GitHub ](https://github.com/curvefi/curve-xgov/blob/master/contracts/Vault.vy).

A comprehensive list of all deployed contracts is available [here ↗](../../../deployments.md).

:::

This contract is directly controlled by its `owner`, which is the `OwnershipAgent` of the respective chain.

---

## Transferring Assets

The contract features a transfer function that allows the `owner` to transfer tokens out of the Vault to a specified receiver address.

### `transfer`
::::description[`Vault.transfer(_token: address, _to: address, _value: uint256)`]

:::guard[Guarded Method]

This function can only be called by the `owner` of the contract, which is the respective chain's `OwnershipAgent`.

:::

Function to transfer a specific amount of tokens from the vault to another address.

| Input     | Type       | Description                  |
| --------- | ---------- | ---------------------------- |
| `_token`  |  `address` | Token to transfer            |
| `_to`     |  `address` | Destination of the asset     |
| `_value`  |  `uint256` | Amount of assets to transfer |

<SourceCode>

```vyper
NATIVE: constant(address) = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE

owner: public(address)

@external
def transfer(_token: address, _to: address, _value: uint256):
    """
    @notice Transfer an asset
    @param _token The token to transfer, or NATIVE if transferring the chain native asset
    @param _to The destination of the asset
    @param _value The amount of the asset to transfer
    """
    assert msg.sender == self.owner

    if _token == NATIVE:
        send(_to, _value)
    else:
        assert ERC20(_token).transfer(_to, _value, default_return_value=True)
```

</SourceCode>

<Example>

This example transfers 1 ARB token from the vault to `0x0000000000000000000000000000000000000000` on Arbitrum.

```shell
>>> Vault.transfer('0x912CE59144191C1204E64559FE8253a0e49E6548', '0x0000000000000000000000000000000000000000', 1000000000000000000)
```

</Example>

## Contract Ownership

Ownership of the Vault contract follows the classic model of contract ownership. It includes an `owner` address, which can be updated by first committing a future owner and then applying the changes. More on transfering ownership can be found [here](../../../resources/curve-practices.md#commit--apply).
