Solana: Decoding data that is owned by Raydium Authority V4

Decoding Base64 Encoded Data in Solana: A Guide

As a beginner on the Solana blockchain, you are probably no stranger to WebSockets and subscriptions. However, when it comes to base64 encoded data, things can get tricky.

In this article, we will take a closer look at how to decode base64 encoded data using Raydium Authority V4 (RV4) in Solana.

The Problem: Base64 Encoding and Decoding

Base64 encoding is a widely used method of representing binary data in text format. It is commonly used when transmitting sensitive information over networks because it allows for a compact representation of large amounts of data. However, when you receive the encoded data at the other end, you need to decode it back to its original form.

In Solana, base64 encoding and decoding is handled by the solana-base64-encoded package, which is included in the Solana SDK. To make things more complex, we will use the accountSubscribe method provided by Raydium Authority V4 to subscribe to a specific account’s base vault.

Decoding Base64 Encoded Data

To decode base64 encoded data, you can use the following approach:

• Subscribe to the specified account and get the account’s base vault.

• Use the Solana SDK’s base64::decode() function to unpack the base64 string into a buffer or Uint8Array.

• Decode the buffer or Uint8Array into its original binary form using the base64::decode() function.

Here is some sample code to illustrate this process:

“`rust

use raydium_authority_v4::{

Account,

Base Vault,

};

use solana_sdk::pubkey::{Pubkey, PubkeyCollection};

use solana_sdk::signature::{Signature, SignaturePubkey};

use solana_sdk::transaction::TransactionId ;

use solana_sdk::vec::Vec;

// Subscribe to a specific account and get the base vault

async function subscribe_to_base_vault(

account_id: &str,

public_key: public_key,

) -> Result {

// Assuming you have an Account object created from the account ID

let account = Account::from_account_id(Pubkey::from_str(account_id).unwrap());

// Get the base vault for the specified account

let vault = account.base_vault().await;

Ok (vault)

}

// Subscribe to a specific account and get the base vault using RV4

async function subscribe_to_base_vault_rv4(

account_id: &str,

public_key: public_key,

) -> Result {

// Assuming you have an Account object created from the account ID

let account = Account::from_account_id(Pubkey::from_str(account_id).unwrap());

// Subscribe to a specific base vault using RV4

let base_vault_rv4 = account.base_vault_rv4().await?;

Ok(base_vault_rv4)

}

// Decode the base64 encoded data into binary form

async fn decode_base64(data: Vec) -> Result, String> {

// Assuming you have a base64 decoder function provided by RV4

let decoded_data = base64::decode(&data).await?;

Ok(decoded_data)

}

// Example usage:

async fn main() -> Result<(), String> {

// Subscribe to a specific account and get the base vault using RV4

let account_id = “your_account_id_here”;

let pubkey = Pubkey::from_str(“your_pub_key_here”).unwrap();

let base_vault_rv4 = subscribe_to_base_vault_rv4(&account_id, &pubkey).await?;

// Subscribe to a specific account and get the base vault using accountSubscribe

let subscription = accountSubscribe(&base_vault_rv4.base_vault().await, base_vault_rv4.public_key(), “your_account_id_here”, Pubkey::from_str(“your_pub_key_here”).unwrap()).await?;

let base_vault = subscription.get_last_transaction().await?;

// Decode base64 encoded data into binary form

let decoded_data = decode_base64(&base_vault.data).await?;
