Welcome to our guide on how to get started with the DeFiChain Jellyfish SDK, a powerful collection of TypeScript and JavaScript tools designed for crafting native DeFi products. In this post, we will walk you through the essentials of using this SDK, unraveling its potential for developers of all levels.

Getting Started with Jellyfish SDK

The Jellyfish SDK is organized using a monorepo methodology which means that all the packages you will use are housed in a single repository. This setup not only allows you to keep track of all components at once but also ensures that they are all published with the same version tag.

Installing the Jellyfish SDK

• Open your terminal.
• Use the following command to install the Jellyfish SDK via npm:

npm install @defichain/jellyfish-network

• After installation, you can start integrating the SDK into your TypeScript or JavaScript projects.

Creating Your First DeFi Product

Once you have the SDK installed, you can create simple DeFi products. Think of it as constructing a sandcastle on the beach. You have the tools (the SDK) and the sand (your coding skills)—what you build depends on how you shape it!

Example Code Snippet

The method to create a simple DeFi product can be illustrated through code:

import { Client } from '@defichain/jellyfish-network';

const client = new Client({ network: 'testnet' });

async function getBlockCount() {
    const blockCount = await client.blockchain.getBlockCount();
    console.log(`Current block count: ${blockCount}`);
}

getBlockCount();

In this snippet, we create a new client that connects to the DeFi testnet and fetches the current block count. Much like using a tape measure to check how tall your sandcastle is, this code helps you understand the state of your DeFi application.

Troubleshooting Common Issues

If you encounter any issues while using the Jellyfish SDK, here are some troubleshooting tips:

• **Error: Module not found**: Ensure the SDK is correctly installed and your project dependencies are up-to-date. Running npm install again can help.
• **Network issues**: If you’re unable to connect, double-check your network settings and ensure you are pointed at the correct DeFi network (mainnet or testnet).
