# Send Solana transactions using solana/web3.js

> Send SOL transactions programmatically using solana-web3.js with a Chainstack Solana node, covering keypair generation, transfers, and transaction signing.

<AccordionGroup>
  <Accordion title="Overview">
    This recipe shows how you can use the solana/web3.js library to send transactions programmatically using a Solana Chainstack node.
  </Accordion>

  <Accordion title="Environment setup">
    Install [node.js](https://nodejs.org/) if it is not installed yet.

    Create a new directory for your project, then install the `solana/web3.js` and `bs58` libraries:

    `npm install --save @solana/web3.js bs58`
  </Accordion>

  <Accordion title="Get your Chainstack endpoint">
    To run this code, you will need a Chainstack account and a Solana Elastic node.

    1. [Sign up with Chainstack](https://console.chainstack.com/user/account/create).
    2. [Deploy a node](https://docs.chainstack.com/docs/manage-your-networks).
    3. [View node access and credentials](https://docs.chainstack.com/docs/manage-your-node#view-node-access-and-credentials).
  </Accordion>

  <Accordion title="The code">
    This script starts by importing the necessary libraries.

    @solana/web3.js is the Solana JavaScript API, which provides the functionality needed to interact with the Solana blockchain. bs58 is a library for encoding and decoding data in base58, a binary-to-text encoding often used in cryptocurrencies.
  </Accordion>

  <Accordion title="Connection and accounts setup">
    The `connection` const establishes a connection to the Solana blockchain using a Chainstack endpoint.

    The next few lines set up two accounts. The first account is created from a private key. The second account is a new account that's generated on the fly to be a fresh recipient account.
  </Accordion>

  <Accordion title="The transfer function">
    This is an `async` function to transfer a certain amount of Lamports, the smallest unit of the SOL token in Solana, from the first to the second account. In this case, it's sending 0.001 SOL (LAMPORTS\_PER\_SOL \* 0.001).

    It then sends the transaction and waits for confirmation.
  </Accordion>

  <Accordion title="Run the code">
    Now you can get your endpoint and paste it into the connection const.

    Then you can run it with `node YOUR_SCRIPT_NAME`

    The transaction has been sent successfully if you don't get any errors in the console.
  </Accordion>

<RequestExample>
  ```js index.js theme={"system"}
  const web3 = require("@solana/web3.js");
  const bs58 = require("bs58");

  const connection = new web3.Connection('YOUR_CHAINSTACK_ENDPOINT');

  const privateKey = new Uint8Array(bs58.decode('YOUR_PRIVATE_KEY'));
  const account = web3.Keypair.fromSecretKey(privateKey);
  const account2 = web3.Keypair.generate();

  (async () => {
    const transaction = new web3.Transaction().add(
      web3.SystemProgram.transfer({
        fromPubkey: account.publicKey,
        toPubkey: account2.publicKey,
        lamports: web3.LAMPORTS_PER_SOL * 0.001,
      }),
    );
    const signature = await web3.sendAndConfirmTransaction(
      connection,
      transaction,
      [account],
    );
  })();
  ```
