# transferOwnership

The `transferOwnership` method facilitates the transfer of contract control from the current owner (often the deployer) to another Ethereum address. This functionality proves useful in various scenarios, such as delegating control to a governance mechanism or facilitating contract upgrades. Upon completion, the new owner gains access to critical functions that may have been restricted to the previous owner only.

**Note**: While this method is commonly present in contracts with ownership mechanisms, it may not be part of the standard ERC20 token. Ensure that the targeted contract implements this functionality.

### Function Signature

```javascript
transferOwnership(to: string, signer: WalletSigner): Promise<string>
```

#### Parameters

| Parameter | Type         | Description                                                                                                                                                                        |
| --------- | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| to        | string       | The Ethereum address designated to assume ownership of the contract. contract.                                                                                                     |
| signer    | WalletSigner | The wallet signer instance representing the current owner, responsible for signing the transaction. Typically generated using the `createWalletSigner` method from `ZkyugaClient`. |

#### Returns

* A `Promise` resolving to a `string`, which represents the transaction hash of the ownership transfer.

### Usage Example

Begin by ensuring that you have properly instantiated the contract for which you intend to transfer ownership:

```javascript
const contractInstance = zkyugaClient.getContractInstance("ContractAddressHere");
```

Then, use the `transferOwnership` method:

```javascript
const newOwnerAddress = "0xBbF289D846208c16EDc8474705C748aff07732dB";
const signer = zkyugaClient.createWalletSigner("current owner's private key");

const transactionHash = await contractInstance.transferOwnership(newOwnerAddress, signer);
```

### Considerations

* Only the current owner of the contract can initiate the `transferOwnership` method. Ensure that the signer corresponds to the address of the current owner.
* Upon completion of the ownership transfer, the previous owner forfeits any special permissions associated with contract ownership
* Exercise caution and verify the receiving address (to) to guarantee that ownership is transferred to the intended address, as this action is typically irreversible.
