Solana: Is there any way to land transactions within 1-2 blocks without relying on an expensive SWQoS provider?

Landing Transactions within 1-2 Blocks without SWQoS Provider: A Solana-Specific Solution

As a trader or developer executing swaps on Solana, you’re likely aware of the importance of landing transactions quickly. However, navigating through the Solana blockchain can be a cumbersome process, especially when relying solely on the expensive SWQoS (Solana Web3 Quality of Service) provider. In this article, we’ll explore alternative methods to land transactions within 1-2 blocks without breaking the bank.

The Challenges with SWQoS

Before diving into the solution, let’s quickly address the challenges associated with using SWQoS:

• High costs: The fees for executing complex transactions can be astronomical.

• Network congestion: Solana has experienced network congestion in the past, making it difficult to execute transactions quickly.

A Solution Using a Dedicated Paid Node (SWT)

One potential solution is to utilize a dedicated paid node, which can provide faster and more reliable transaction execution. Here’s an overview of how you can use a SWT (Smart Wallet Transaction) to land transactions within 1-2 blocks:

Step 1: Set up a SWT

You’ll need to install the Solana Node Manager (SNM) or the Solana Wallet App, which will provide access to your dedicated node.

Step 2: Configure Your SWT

Once set up, configure your SWT to connect to your dedicated node. This typically involves setting the node’s address and port number in your app’s configuration file (e.g., solana.config.js).

Step 3: Use SendRawTransaction

To execute a transaction using your SWT, simply call the sendRawTransaction() method with your desired transaction data.

import { Web3Provider } from "@solana/web3.js";

import { sendRawTransaction } from "web3-utils";


const web3 = new Web3Provider(

  // Your node's address and port number

  '

);

Step 4: Use getTransaction to Retrieve the Transaction ID

After executing a transaction using sendRawTransaction(), you can retrieve the transaction ID (txid) using the getTransaction() method.

const transaction = await web3.getAccount();

const txId = transaction.id;

Step 5: Land the Transaction within 1-2 Blocks

With your SWT, you now have control over the transaction execution process. You can land the transaction within a shorter period of time by:

• Using the sendRawTransaction() method with an optional minCost parameter set to a lower value (e.g., -200).

• Combining multiple transactions into a single operation using the Solana Web3 API.

• Utilizing the getTransactionId() method to retrieve the transaction ID earlier, which can then be used to execute the transaction.

Here’s an example of how you could implement these steps:

“`typescript

import { sendRawTransaction } from “web3-utils”;

import { getAccount } from “@solana/web3.js”;

const web3 = new Web3Provider(

// Your node’s address and port number

‘

);

// Define a function to execute the transaction using SWT

async function landTransaction(transactionData) {

const tx = await sendRawTransaction(

transactionData,

{ minCost: -200 } // Set the minimum cost for transaction execution

);

const transactionId = tx.id;

return transactionId;

}

// Define a function to retrieve the transaction ID earlier

async function getTransactionId(transactionId) {

const account = await web3.getAccount();

return account.id;

}

// Example usage:

const transactionData = { // Your desired transaction data

accounts: [

// List your desired accounts here

],

};

const txid = await landTransaction(transactionData);

// Use the transaction ID to execute the original transaction using getTransaction()

const originalTxId = await web3.
