# 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.kiln.fi/v1/kiln-products/onchain/node-operators-how-to-integrate/pooled-staking/5.-depositing-via-integration-contracts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
