Introducing the Coinbase Prime and International Exchange (INTX) Java SDKs

To expand our existing coverage of Coinbase Institutional products with sample SDKs, Coinbase released the Prime Java SDK and International Exchange (INTX) Java SDK. These SDKs provide essential tools and libraries to interact directly with Coinbase Prime and INTX.

Java remains one of the most widely used programming languages in the world, especially among financial institutions. Its reliability and performance have proven to be critical in trading environments where latency and stability can significantly impact outcomes. Java's cross-platform compatibility ensures that applications can run on various operating systems without modification, making it a versatile choice for developers. Moreover, our clients have emphasized the need for robust Java SDKs to integrate their trading systems with our Institutional APIs.

Functionality

The Prime and INTX Java SDKs offer a wide array of functionalities designed to simplify and enhance client interaction with Coinbase's trading platforms. Here are some key features:

• Authentication and Authorization: Simplified handling of API keys and secrets, ensuring secure and authenticated requests

• Order Management: Create, modify, and cancel orders with ease. Includes support for complex order types and parameters

• Portfolio Management: Manage and monitor  trading portfolios, view balances, and track performance

• Transfer and Settlement: Handle internal transfers between portfolios, withdraw to crypto addresses, and track transactions

• Error Handling: Robust error handling and response parsing to ensure smooth operation and easy debugging

Both SDKs are built using a shared core Java library, ensuring consistency in the features mentioned above. This allows both SDKs to be used in conjunction without needing to write bespoke handlers.

Running it yourself The Coinbase Prime and INTX Java SDKs are both vended through Maven. To use these in your own project, install the dependencies using Maven:

<dependency>

    <groupId>com.coinbase.intx</groupId>

    <artifactId>coinbase-intx-sdk-java</artifactId>

    <version>x.y.z</version>

</dependency>

<dependency>

    <groupId>com.coinbase.prime</groupId>

    <artifactId>coinbase-prime-sdk-java</artifactId>

    <version>x.y.z</version>

</dependency>

Before running the above, make sure to check for the latest version on Maven.

To use the Coinbase Prime or INTX Java SDK, initialize the Credentials class and create a new client. The Credentials class is JSON-enabled, making it easy to securely store and manage API credentials. Ensure that Prime or INTX API credentials are stored in a secure manner, such as in ~/.zshrc or ~/.bashrc.

First, initialize the Credentials class and create a new client. See an example of this inside of the examples package.

String credsStringBlob = System.getenv("COINBASE_PRIME_CREDENTIALS"); // or INTX_CREDENTIALS

        ObjectMapper mapper = new ObjectMapper();

CoinbaseCredentials credentials = mapper.readValue(credsStringBlob, CoinbaseCredentials.class); CoinbaseHttpClient client = new CoinbaseHttpClient.Builder(credentials)

.withClient(java.net.http.HttpClient.newHttpClient())

.build();

To see a working example of the SDKs, each repository contains an examples package that highlights how to construct the corresponding SDK Client, instantiate Credentials, and call several API requests: INTX example, Prime example.

public class Main {

    public static void main(String[] args) throws CoinbaseIntxException {

        String credsStringBlob = System.getenv("INTX_CREDENTIALS");

        ObjectMapper mapper = new ObjectMapper();

        try {

            CoinbaseCredentials credentials = new CoinbaseCredentials(credsStringBlob);

            CoinbaseIntxHttpClient client = new CoinbaseIntxHttpClient(credentials);

            ListPortfoliosRequest listReq = new ListPortfoliosRequest.Builder()

                    .build();

            ListPortfoliosResponse listResponse = client.listPortfolios(listReq);

            System.out.println("List Portfolios Response:");

            System.out.println(mapper.writerWithDefaultPrettyPrinter().writeValueAsString(listResponse));

        } catch (Throwable e) {

            throw new CoinbaseIntxException("Failed to retrieve the list portfolios response", e);

        }

    }

}

The release of the Prime Java SDK and International Exchange (INTX) Java SDK marks a significant step in enhancing our support for institutional traders. By providing these comprehensive Java SDKs, we are catering to the specific needs of financial institutions, ensuring they have the tools necessary for efficient and secure trading. - -
