Monitoring of Changes in Raydium Groups: External Accounts Monitoring in Solana
Solana, a popular blockchain platform, offers several characteristics and tools for developers to track and monitor changes in decentralized applications (DApps). One of these characteristics is’ onprogramacountchange, which allows listeners to detect changes in program accounts, including external accounts. In this article,
What is onprogramacountchange?
Onprogramaccoucchangeis an event issued by Solana's Execution time when a program account changes its property or access control. This event provides.

To track the changes in raidium groups for external accounts that useonprogramaccountchange, they must:

Example Code
JavaScript
Const {Programcountchangelistener} = Require ('@Solana-Teacher/Lib/Types');
Const {onprogramacountchange, programdress} = Require ('Solana-Program/Program-Program-Account-Change');
// Import the Desired Program Address for Raydium Pools
Consta RaydiummoolProgramaddress = 'Raydium_pool';
// Configure the Listener's Function to Detect External Accounts
Async Funtion Liste Goyforcches (Programacountchange) {
// Define a Call Return Function that will be called when a program account change occurs
Async Function Handlprogramaccounge (Event) {
Console.log (external account changed: $ {event.programid.tostring ()} -> $ {event.newowner.tostring ()});
}
// Add the listener to the Program Address
Wait onprogramacountchange (
Programedss Program,
Raydiummoolprogramaddress,
Handlprogramacuntchange
);
}
// Configure a Call Return Function for When The Program is Initial
Async Function Initialininsisner (programcontchagange) {
Console.log ('initialized program');
// Add the listener to the Program Address
Wait onprogramacountchange (
Programedss Program,
Raydiummoolprogramaddress,
Handlprogramacuntchange
);
}
// Initialize listeners to get
Listenforchanges ();
Initializelisterner (programacchange);
