# XVSBridgeAdmin

## XVSBridgeAdmin

The XVSBridgeAdmin contract extends a parent contract AccessControlledV8 for access control, and it manages an external contract called XVSProxyOFT. It maintains a registry of function signatures and names, allowing for dynamic function handling i.e checking of access control of interaction with only owner functions.

## Solidity API

#### functionRegistry

A mapping keeps track of function signature associated with function name string.

```solidity
mapping(bytes4 => string) functionRegistry
```

***

#### fallback

Invoked when called function does not exist in the contract.

```solidity
fallback(bytes data) external returns (bytes)
```

**Return Values**

| Name | Type  | Description                 |
| ---- | ----- | --------------------------- |
| \[0] | bytes | Response of low level call. |

**⛔️ Access Requirements**

* Controlled by AccessControlManager.

***

#### setTrustedRemoteAddress

Sets trusted remote on particular chain.

```solidity
function setTrustedRemoteAddress(uint16 remoteChainId_, bytes remoteAddress_) external
```

**Parameters**

| Name            | Type   | Description                        |
| --------------- | ------ | ---------------------------------- |
| remoteChainId\_ | uint16 | Chain Id of the destination chain. |
| remoteAddress\_ | bytes  | Address of the destination bridge. |

**⛔️ Access Requirements**

* Controlled by AccessControlManager.

**❌ Errors**

* ZeroAddressNotAllowed is thrown when remoteAddress\_ contract address is zero.

***

#### upsertSignature

A setter for the registry of functions that are allowed to be executed from proposals.

```solidity
function upsertSignature(string[] signatures_, bool[] active_) external
```

**Parameters**

| Name         | Type      | Description                                 |
| ------------ | --------- | ------------------------------------------- |
| signatures\_ | string\[] | Function signature to be added or removed.  |
| active\_     | bool\[]   | bool value, should be true to add function. |

**📅 Events**

* Emits FunctionRegistryChanged if bool value of function changes.

**⛔️ Access Requirements**

* Only owner.

***

#### transferBridgeOwnership

This function transfers the ownership of the bridge from this contract to new owner.

```solidity
function transferBridgeOwnership(address newOwner_) external
```

**Parameters**

| Name       | Type    | Description                  |
| ---------- | ------- | ---------------------------- |
| newOwner\_ | address | New owner of the XVS Bridge. |

**⛔️ Access Requirements**

* Controlled by AccessControlManager.

***

#### isTrustedRemote

Returns true if remote address is trustedRemote corresponds to chainId\_.

```solidity
function isTrustedRemote(uint16 remoteChainId_, bytes remoteAddress_) external returns (bool)
```

**Parameters**

| Name            | Type   | Description                        |
| --------------- | ------ | ---------------------------------- |
| remoteChainId\_ | uint16 | Chain Id of the destination chain. |
| remoteAddress\_ | bytes  | Address of the destination bridge. |

**Return Values**

| Name | Type | Description                                                 |
| ---- | ---- | ----------------------------------------------------------- |
| \[0] | bool | Bool indicating whether the remote chain is trusted or not. |

**❌ Errors**

* ZeroAddressNotAllowed is thrown when remoteAddress\_ contract address is zero.

***

#### renounceOwnership

Empty implementation of renounce ownership to avoid any mishappening.

```solidity
function renounceOwnership() public
```

***
