# spark\_flashnet\_addLiquidity

{% hint style="info" %}
This method is coming :soon:
{% endhint %}

Use the `spark_flashnet_addLiquidity` method to request a Flashnet liquidity provision directly from the user’s Spark wallet.

Your app provides the pool and asset parameters (asset A/B amounts, minimum amounts, etc.), and the wallet handles the full process:

* Initiates the Spark transfers for both assets
* Generates and signs the liquidity intent
* Submits to Flashnet
* Returns the result (success, partial acceptance, or rejection)

This abstracts all complexity into a **single request**, making liquidity provision simple and secure.

***

## 📦 Example

```ts
import { request } from "sats-connect";

try {
  const response = await request("spark_flashnet_addLiquidity", {
    poolId: "03aabbccddeeff00112233445566778899aabbccddeeff00112233445566778899",
    assetAAmountToAdd: "100000000", // sats or smallest units
    assetAMinAmountIn: "95000000",
    assetBAmountToAdd: "50000",
    assetBMinAmountIn: "45000",
    userPublicKey: "03abcdef0123456789abcdef0123456789abcdef0123456789abcdef01234567",
    nonce: "add-liquidity-1702934567890"
  });

  if ("result" in response) {
    console.log("Liquidity result:", response.result);
  } else {
    console.error("Add liquidity failed:", response.error.message);
  }
} catch (error) {
  console.error("Unexpected error:", error);
}
```

## 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.xverse.app/sats-connect/spark-methods/flashnet-trading/spark_flashnet_addliquidity.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.
