Wrap SOL

The wrapSol action converts native SOL into Wrapped SOL (wSOL) — an SPL token version of SOL. If you need to convert it back, just buy or sell any token on pump-amm. This will automatically close the wSOL token account and return everything back to SOL.

Code Examples

Python

import aiohttp
import asyncio

async def wrap_sol():
    url = "https://api.pumpapi.io"
    data = {
        "privateKey": "base58_private_key", # or use "apiKey": "your_api_key" instead — generate one at pumpapi.io/trade-api (🔑 spoiler)
        "action": "wrapSol",
        "amount": "0.5",
        "priorityFee": "0.00002",
    }
    async with aiohttp.ClientSession() as session:
        async with session.post(url, json=data) as response:
            result = await response.json()
            print(result)

asyncio.run(wrap_sol())

JavaScript

const response = await fetch("https://api.pumpapi.io", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    privateKey: "base58_private_key", // or use "apiKey": "your_api_key" instead — generate one at pumpapi.io/trade-api (🔑 spoiler)
    action: "wrapSol",
    amount: "0.5",
    priorityFee: "0.00002",
  }),
});

const result = await response.json();
console.log(result);

Go

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "net/http"
)

func main() {
    payload := map[string]string{
        "privateKey":  "base58_private_key", // or use "apiKey": "your_api_key" instead — generate one at pumpapi.io/trade-api (🔑 spoiler)
        "action":      "wrapSol",
        "amount":      "0.5",
        "priorityFee": "0.00002",
    }

    body, _ := json.Marshal(payload)
    resp, err := http.Post("https://api.pumpapi.io", "application/json", bytes.NewBuffer(body))
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    var result map[string]interface{}
    json.NewDecoder(resp.Body).Decode(&result)
    fmt.Println(result)
}

Rust

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let payload = json!({
        "privateKey": "base58_private_key", // or use "apiKey": "your_api_key" instead — generate one at pumpapi.io/trade-api (🔑 spoiler)
        "action": "wrapSol",
        "amount": "0.5",
        "priorityFee": "0.00002"
    });

    let res = client
        .post("https://api.pumpapi.io")
        .json(&payload)
        .send()
        .await?;

    println!("{}", res.text().await?);
    Ok(())
}
