# Adding Authorized Traders

You may want to grant or revoke approval from a particular Ethereum address to make trades on behalf of your Vault. Below is the process for querying which addresses are currently and editing that list appropriately.

```typescript
import { IntegrationManager } from '@enzymefinance/protocol';
import { providers, Wallet } from 'ethers';

// an example provider
const provider = providers.StaticJsonRpcProvider(ethNodeAddress, ethNetwork); 

// an example wallet (a subclass of Signer that can be called directly)
const wallet = new Wallet(investorsEthPrivateKey, provider)

// the IntegrationManager contract address, available at contracts.enzyme.finance
const integrationManagerAddress = '0x23k20d...';

// the Vault's comptroller address, available at the vault dashboard at app.enzyme.finance
const vaultComptrollerAddress = '0x2d9es...';

// an arbitrary address; we'll permission it if it's not already and
// revoke permission if it is.
const arbitraryAddress = '0x94d0s...';

// instantiate the Integration Manager contract
const integrationManagerContract = new IntegrationManager(
    integrationManagerAddress,
    wallet,
);

// determine whether the arbitrary address is currently permissioned
const isCurrentlyPermissioned = await integrationManagerContract.isAuthUserForFund(
    vaultComptrollerAddress,
    arbitraryAddress,
);

// conditionally instantiate the transaction
const authUserTx = !isCurrentlyPermissioneded
    ? integrationManagerContract.addAuthUserForFund.args(
        vaultComptrollerAddress,
        arbitraryAddress,
    ) 
    : integrationManagerContract.removeAuthUserForFund.args(
        vaultComptrollerAddress,
        arbitraryAddress,
    );

// send the transaction
const authUserTxReceipt = await authUserTx.send();
console.log('Pending transaction:', authUserTxReceipt.hash);
console.log('Transaction included in block number:', authUserTxReceipt.blockNumber);

```
