This article explains where to find the methods “getTransactionCounters” and “getTransactions” in Solana’s RpcClient:
Understanding Solana’s RPC Client Methods
You can use Solana’s Remote Procedure Call (RPC) Client to interact with the Solana network. The RPC client is responsible for sending requests to a Solana node and receiving responses. One of the most important features of the RPC client is its ability to retrieve multiple transaction data at once.
`getTransactionCounters’
The getTransactionCounters method allows you to retrieve a list of counters for each account in your Solana public key space. These counters include things like the maximum balance, the minimum balance, and the maximum number of transactions per block.
You can use this method by calling it on an RpcClient instance and specifying the account addresses for which you want to retrieve the counts.
use solana_program::rpc_client::{RpcClient, RpcError};
use solana_program::account_info::{AccountInfo, ProgramAccount};
// Set the public key state and account information.
pub type PublicKey = AccountInfo;
pub type PublicKeySpace = [ PublicKey ; 32];
#[tokyo::main]
async fn main() -> Result<(), RpcError> {
// Create a new RPC client instance.
let rpc_client = RpcClient::new("
// Set the public key state and account information.
let public_key_space: PublicKeySpace = [PublicKey::new(b"pubkey1"), PublicKey::new(b"pubkey2")];
// Get transaction counts for all accounts in the public key space.
rpc_client
.get_transaction_counts(&public_key_space) .
.wait?
.into_iter()
.for_each(|(counters, _, _)| {
println!("{:?}", counters);
})
} }
“getTransactions”.
The getTransactions method is used to retrieve the transaction list for each account in the public key space of your Solana program.
You can use it just like “getTransactionCounters”, but with a few differences. The “getTransactions” function returns a “TransactionListResponse” containing a list of transactions.
You can use this method by calling it on an RpcClient instance and specifying the account addresses for which you want to retrieve transactions.
use solana_program::rpc_client::{RpcClient, RpcError};
use solana_program::account_info::{AccountInfo, ProgramAccount};
// Set the public key state and account information.
pub type PublicKey = AccountInfo;
pub type PublicKeySpace = [ PublicKey ; 32];
#[tokyo::main]
async fn main() -> Result<(), RpcError> {
// Create a new RPC client instance.
let rpc_client = RpcClient::new("
// Set the public key state and account information.
let public_key_space: PublicKeySpace = [PublicKey::new(b"pubkey1"), PublicKey::new(b"pubkey2")];
// Get transactions for all accounts in public key space.
rpc_client
.get_transactions(&public_key_space) .
.wait?
.into_iter()
.for_each(|(transactions, _, _)| {
println!("{:?}", transactions);
})
} }
Conclusion
To summarize, to get multiple transaction data at once in Solana using an RPC client, you can use “getTransactionCounters” for counters and “getTransactions” for transactions. Both methods allow you to retrieve a list of transactions or counts for each account in the public key space of your Solana program.
Keep in mind that specific method calls and their usage may vary depending on the version of Solana and the RPC client library used. Always refer to the official documentation for more information on how to use these methods.
