Title: Solana: Doubts about GetTransactionCount, Not Working As Intended
Introduction
Solana is a popular blockchain platform known for its fast and secure transactions. When building a program that interacts with the solana network, it is essential to understand how different functions work. In this article, we’ll explore We’ll also discuss some doubt when trying out these functions.
Getting Root Slot Number
To get the root number in solana, you can use the slotsubscribe function provided by the solana sdk. Here’s an example of how to use it:
`rust
Use Solana-Program :: {
Account_info :: {Next_account_info, Accountinfo},
Entrypoint,
EntryPoint :: Programresult,
Program_error :: Printerror,
PUBKEY :: Pubkey,
};
EntryPoint! (Program);
Fn Main () -> Programresult {
// Get the Root Slot Number from the Account Info
let (slot_number, _) = next_account_info (& accountinfo :: new_indexed ());
Println! (“Root Slot number: {}”, slot_number);
Ok (())
}
`
In this example, we’re subscribing to the slot event on a specific slot (1). When an event occurs with slot number 1, we’ll get the corresponding account information. Let’s Dive Deeper into how to use gettransactioncount.
Using GetTransactionCount
The GetTransactionCount Function in Solana returns the total number of finalized transactions for a given block. . Here’s an example:
`rust
use solana_program :: {
Account_info :: {Next_account_info, Accountinfo},
Entrypoint,
EntryPoint :: Programresult,
Program_error :: Printerror,
PUBKEY :: Pubkey,
};
EntryPoint! (Program);
Fn Main () -> Programresult {
// Get the Index of the Block (1 In This Case)
let block_index = next_account_info (& accountinfo :: new_indexed ()). Pubkey;
// Call GetTransactionCount With The Block Index
Let transaction_count = Solana_program :: Get_transaction_count (block_index)?;
Println! (“Number of Transitions: {}”, transaction_count);
Ok (())
}
`
In this example, we’re getting the account info for the second slot (2). Then, we call gettransactioncount with the block index. This function returns a U128 value representing the total number of finalized transactions.
DUBTS
After trying out these functions in our example programs, we encountered some doubted:
Slotsubscribeis designed to work with theslotevent, which triggers when a new slot is created or an existing one is updated.
- We need to use
block_indexinstead to get the correct result.
.
Conclusion
Solana: gettransactioncount and its usage withslotsubscribe. We Functions, you’ll be well on your way to create a powerful programs that interact with the solana network.
