Landing Transactions Within 1-2 Blocks Without a SWQoS Provider: A Solana-Specific Solution
As a trader or developer running swaps on Solana, you’re probably aware of the importance of executing transactions quickly. However, navigating the Solana blockchain can be a complicated process, especially when relying solely on the expensive SWQoS (Solana Web3 Quality of Service) provider. In this article, we’ll explore alternative methods for executing 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 Smart Wallet Transaction (SWT) to perform transactions within 1-2 blocks:
Step 1: Set up a SWT
You’ll need to install the Solana Node Manager (SNM) or Solana Wallet app, which will provide you with access to your dedicated node.
Step 2: Configure your SWT
Once configured, configure your SWT to connect to your dedicated node. This typically involves setting the node address and port number in your application’s configuration file (e.g. solana.config.js).
Step 3: Use SendRawTransaction
To perform a transaction using your SWT, simply call the sendRawTransaction() method with the desired transaction data.
import { Web3Provider } from "@solana/web3.js";
import { sendRawTransaction } from "web3-utils";
const web3 = new Web3Provider(
// Your node 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: Complete the transaction in 1-2 blocks
With your SWT, you now have control over the transaction execution process. You can complete the transaction in a shorter amount of time:
- Using the
sendRawTransaction()method with an optionalminCostparameter set to a smaller value (e.g.-200).
- Combining multiple transactions into a single operation using the Solana Web3 API.
- Using the
getTransactionId()method to retrieve the transaction ID previously, which can then be used to execute the transaction.
Here is an example of how you can implement these steps:
“`typescript
import { sendRawTransaction } from ” web3-utils “;
import { getAccount } from “@solana/web3.js”;
const web3 = new Web3Provider(
// Your node address and port number
‘
);
// Define a function to execute the transaction using SWT
async function landTransaction ( transactionData ) { ;
const tx = await sendRawTransaction(
transaction data,
{ minCost : -200 } // Set the minimum cost to execute the transaction
);
const transactionId = tx.id;
return transactionId;
} }
// Define a function to retrieve the transaction ID previously
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 .
