Solana: Decoding data that is owned by Raydium Authority V4

Decoding Base64 Encoded Data in Solana: A Guide

As a beginner to the Solana blockchain, WebSockets and Subscriptions are probably familiar to you. However, when it comes to dealing with base64 encoded data, things can get tricky.

In this article, we will take a closer look at decoding base64 encoded data using Solana’s Raydium Authority V4 (RV4).

Problem: Base64 encoding and decoding

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

In Solana, the “base64” encoding and decoding is handled by the “solana-base64-encoded” package, which is included in the Solana SDK. We make things more complicated by using the “accountSubscribe” method provided by Raydium Authority V4 to subscribe to the base vault for a specific account.

Decoding Base64-encoded data

You can decode base64-encoded data as follows:

• Subscribe to the specified account and get the base vault for the account.

• Decode the base64 string into a buffer or Uint8Array using the Solana SDK’s base64::decode() function.

• Decode the buffer or Uint8Array back to its original binary form using thebase64::decode() function.

Here is some sample code to illustrate this process:

“` rust

use raydium_authority_v4::{

Account,

BaseVault,

};

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 fn subscribe_to_base_vault(

accountid: &str,

pubkey: Pubkey,

) -> Result {

// Assuming you have an account object created from the accountid

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().wait;

Ok (vault)

}

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

async fn subscribe_to_base_vault_rv4(

account_id: &str,

pubkey: Pubkey,

) -> Result {

// Assuming you have an account object created from an 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().wait?;

Ok(base_vault_rv4)

}

// Decode the base64 encoded data back to binary

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

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

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

Ok(decoded_data)

}

// Usage example:

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

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

let account_id = “your_pubkey_here”;

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

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

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

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

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

// Decode the base64 encoded data back to binary

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

println!(“{:x?
