# spark\_flashnet\_createBondingPool

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

Use the `spark_flashnet_createBondingPool` method to request the creation of a **bonding curve pool** (single-sided pool) on Flashnet directly from the user’s Spark wallet.

Bonding pools are typically used for **token launches**, where liquidity grows gradually along a curve until a graduation threshold is reached.

***

## 📦 Example

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

try {
  const response = await request("spark_flashnet_createBondingPool", {
    assetAAddress: "0338d6978bd3163d1547f9ddb8b215d1c163bc7b4a552e559b89057f5449ba69de",
    assetAInitialReserve: "1000000000", // sats or smallest units
    assetBAddress: "020202020202020202020202020202020202020202020202020202020202020202",
    graduationThresholdPct: 50, // % of target to trigger graduation
    hostNamespace: "my-cool-exchange",
    lpFeeRateBps: 500, // 5.00%
    totalHostFeeRateBps: 200, // 2.00%
    targetBRaisedAtGraduation: "10000000000", // target raise
    poolOwnerPublicKey: "03b06b7c3e39bf922be19b7ad5f19554bb7991cae585ed2e3374d51213ff4eeb3c",
    nonce: "550e8400-e29b-41d4-a716-446655440000"
  });

  if ("result" in response) {
    console.log("Bonding pool created:", response.result);
  } else {
    console.error("Pool creation failed:", response.error.message);
  }
} catch (error) {
  console.error("Unexpected error:", error);
}
```
