🛠️SDKs

SDKs for building the future of Solana

At Helius, we've developed a Node.js and a Rust SDK to make developing on Solana easier. The following page includes information on installing and using these SDKs. It also covers common error handling, where to find the latest documentation, and how to contribute to these SDKs. We also outline a list of unofficial community SDKs made by our wonderful community. Note that those SDKs are not officially maintained by our team — only the Node.js and Rust SDKs are

Node.js SDK

Installation

The Helius Node.js SDK can be installed with any of the following package managers:

Package Manager
Command

npm

npm install helius-sdk

pnpm

pnpm install helius-sdk

Yarn

yarn add helius-sdk

Quick Start

Here's a straightforward example of how to use the Node.js SDK to fetch a list of assets owned by a given address:

import { Helius } from "helius-sdk";

const helius = new Helius("YOUR_API_KEY");
const response = await helius.rpc.getAssetsByOwner({
  ownerAddress: "86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY",
  page: 1,
});

console.log(response.items);

Documentation

The README file is filled with in-depth code examples covering each method and basic usage. For API reference documentation, refer to our documentation and the official Solana documentation for general Solana JSON RPC API help.

Rust SDK

Installation

To start using the Helius Rust SDK in your project, add it as a dependency via cargo. Open your project's Cargo.toml and add the following line under [dependencies]:

helius = "x.y.z"

where x.y.z is your desired version. Alternatively, use cargo add helius to add the dependency directly via the command line. This will automatically find the latest version compatible with your project and add it to your Cargo.toml.

Remember to run cargo update regularly to fetch the latest version of the SDK.

Quick Start

Here is a straightforward example of using the Enhanced Transactions API to parse a given transaction:

use helius::error::Result;
use helius::types::*;
use helius::Helius;

#[tokio::main]
async fn main() -> Result<()> {
    let api_key: &str = "your_api_key";
    let cluster: Cluster = Cluster::MainnetBeta;

    let helius: Helius = Helius::new(api_key, cluster).unwrap();

    let request: ParseTransactionsRequest = ParseTransactionsRequest {
        transactions: vec![
            "2sShYqqcWAcJiGc3oK74iFsYKgLCNiY2DsivMbaJGQT8pRzR8z5iBcdmTMXRobH8cZNZgeV9Ur9VjvLsykfFE2Li".to_string(),
        ],
    };

    let response: Result<Vec<EnhancedTransaction>, HeliusError> = helius.parse_transactions(request).await;
    println!("Assets: {:?}", response);

    Ok(())
}

Documentation

The latest documentation can be found here on docs.rs. For API reference documentation, refer to our documentation and the official Solana documentation for general Solana JSON RPC API help.

More examples of how to use the SDK can be found in the examples directory.

Error Handling

An error message will be thrown when the API returns a non-success (i.e., 4xx or 5xx status code). For example:

// From our Node.js SDK
try {
  const response = await helius.rpc.getAssetsByOwner({
    ownerAddress: "86xCnPeV69n6t3DnyGvkKobf9FdN2H9oiVDdaMpo2MMY",
    page: 1,
  });
  console.log(response.items);
} catch (error) {
  console.log(error);
}

Common Error Codes

When working with the Helius SDK, you may encounter several error codes. Below is a table detailing some of the common error codes along with additional information to help you troubleshoot:

Error Code
Error Message
More Information

401

Unauthorized

This occurs when an invalid API key is provided or access is restricted due to RPC rules.

429

Too Many Requests

This indicates that the user has exceeded the request limit in a given timeframe or is out of credits.

5XX

Internal Server Error

This is a generic error message for server-side issues. Please contact Helius support for assistance.

If you encounter any of these errors:

  • Refer to errors.rs for a list of all possible errors returned by the Helius client, if using the Rust SDK

  • Refer to the Helius documentation for further guidance

  • Reach out to the Helius support team for more detailed assistance

Contribution to Our SDKs

We welcome all contributions to our SDKs! If you're interested, here are our GitHub Repositories:

Unofficial Community SDKs

Our amazing community members have also created their own SDKs to interact with our REST APIs. Please note our team does not officially maintain these. Unofficial community SDKs in other languages include:
