Interacting with BPF_Loader_Program in Solana Web3js: a suitable guide
Solana Blockchain is increasingly popular for the establishment of decentralized applications (Dapps) and the interaction with the network with its JavaScript -SDK. However, one of the main concepts that are a bit difficult to understand is how to interact with the duration of the Basic Programming Language used by Solana with
BPF_Loader_program .
In this article, we will deal with the expected path to interact with BPF_loader_program on Web3JS and provide adequate instructions for effective use.
What is the expected way to interact with BPF_Loader_Program?
BPF_Loader_program is a program that carries binary programs (BPFS) in blockchain Solana. These BPs are essentially the compiled rust code, which can be performed by the duration of solana. The main purpose of this program is to load and perform these BPs, which can vary from simple data processing functions to the complex intelligent contract logic.
To interact with Web3JS with BPF_Loader_program, you must follow a certain workflow:
- Create a new BPF program: First, you must compile a rust program that export the desired functionality as a library (
.so). You can use tools like “Rustc” to create your code.
- Download the BPF loader library
: Once your rust program is created, you must create a new instance of the Solana BPF Loader program with “Solana BPF Loader” from Web3JS. This way you can load your rust program compiled in blockchain Solana.
- Register the BPF Runner Invited Program : After loading the BPF charger, you must register the invited program with the term BPF with
bpf :: load_program ().
- See the Invited Program data : After all, you can consult the charged program data with various web3js functions, such as:
And as forWeb3.bpf_loader_program_id ‘outdated?
As mentioned in your question, bpf_loader_program_id was marked as outdated. However, this does not mean that you should stop it immediately. The Web3JS team is constantly working to update and improve their APIs in order to support more recent functions and alternatives.
In fact, a newer version of Web3JS (1.x) offers an enhanced way to interact with BPF_Loader_program, which we will outline below:
Improved approach with web3js 1.x
With Web3JS 1.x, you can use the following code to load and consult a rust program compiled as Solana Program:
`JavaScript
CONST {solanaprogramdata} = Wait Web3.Loadprogram (
‘Path/to/your/bpf/charger/library.so’,
{
Accounts: [],
Programs: []
}
);
console.log (solanaprogramdata.loadprogramdata ());
`
This code loads the BPF chargers library, records you in the BPF corridor and asks for data from the invited program “Solana Program data” ().

Interaction with BPF_Loader_Program in Solana Web3JS may be a little more involved than other tasks, but understanding the right workflow and alternatives make your development process smoother. If you follow this manual, you can charge, consult and effectively use compiled rust programs by programming with Web3JS programs as Solana.
