# 5. Depositing via Integration Contracts

The last step is deploying an integration contract and connecting it to your `vPool`.

### Deploying an integration contract and connecting it

The deployment of integration contracts is covered on [this page](/v1/kiln-products/onchain/node-operators-how-to-integrate/pooled-staking/7.-deploy-integration-contract-optional.md).

### Test your integration by staking 32 ETH

You should new be able to stake on your integration contract and purchase validator on your `vPool` once 32 ETH is reached 

```solidity
// 20 family stake function
function stake() external payable;

// 1155 family stake function
function stake(uint256[] calldata amounts, uint256[] calldata ids) external payable returns (bool);
```

To facilitate your usage of the integration contracts your can find the `ABIs` of the integration contracts on [this page](/v1/kiln-products/onchain/node-operators-how-to-integrate/pooled-staking/7.-deploy-integration-contract-optional.md).

Once your `vPool` has accumulated 32 ETH and your oracle has reported you should be able to call : 

```solidity
function purchaseValidators(uint256 max) external;
```

This should not revert and a deposit should have happened.

Afterwards you should be able to monitor the growth of your position upon every oracle report.
