How to Build dApps Faster with Web3 APIs

Building on Web3 is getting easier than ever and more and more developers from Web2 are making the transition to Web3. The increasingly scalable and secure next-generation distributed ledger technologies are enabling exciting new real-world use cases and enterprises in various industries are exploring the new business opportunities these novel technologies enable. Developing blockchain ecosystems, and better tools, and services are making Web3 development more accessible for a growing number of businesses.

As a developer, it has never been more relevant to start experimenting with the technology. In this article, we will introduce the concept of dApps and how you can start building on Web3 faster with modern Web3 APIs. Web3 APIs play a crucial role in connecting dApps with blockchain networks, allowing developers to access and index blockchain information and interact with other ecosystem services. Web3 APIs are fundamental for creating secure and user-friendly dApps that scale efficiently.

So let’s get started with a deep dive into Decentralized Applications and what kind of benefits and use cases they enable.

What are Decentralized Applications (dApps)

Decentralized applications (dApps) are a type of applications that operate on a decentralized network, built on blockchain technology. Unlike traditional applications that rely on a central authority or server, dApps distribute their operations across a network of nodes (servers), making them resilient to failures and censorship.

dApps leverage the transparency, security, and immutability of blockchain technology to provide a trustless environment where users can interact directly with the application and the underlying blockchain. This eliminates the need for intermediaries, such as banks or centralized servers, and allows for peer-to-peer transactions and interactions.

dApps offer advantages such as enhanced security, as transactions and data are recorded on the blockchain, making them tamper-proof. They also provide transparency, as the entire transaction history is publicly accessible. Additionally, dApps often utilize smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. This automates processes and ensures that transactions are executed as intended.

dApps are unleashing a wave of innovation across industries, transforming the way we conduct business and interact with various sectors. They provide users with more control over their data and transactions, while also enabling new possibilities for innovative and democratic applications. From finance to healthcare, supply chain management to voting systems, blockchain’s transparency, security, and efficiency are driving positive change.

As you start your journey into Web3 one of the first things you will want to look into are modern scalable Web3 APIs. Let’s take a closer look at what we mean with Web3 APIs.

Introduction to Web3 APIs

Web3 APIs are a set of standards and protocols that enable decentralized applications (dApps) to interact with blockchain networks and access blockchain data. These APIs serve as a bridge between dApps and the underlying blockchain infrastructure, allowing developers to build applications that leverage the benefits of blockchain technology.

Web3 APIs provide developers with the tools and functionalities to interact with blockchain networks, query data, and perform transactions. They enable dApps to access information such as account balances, transaction history, smart contract functions, and more.

These APIs also facilitate the integration of dApps with other services in the blockchain ecosystem. This includes connecting to decentralized exchanges, oracle services, and external APIs, and expanding the capabilities and possibilities of dApps.

Web3 APIs are designed to be developer-friendly and provide a standardized way of interacting with different blockchain networks. They abstract the complexities of blockchain protocols and allow developers to focus on building innovative and user-friendly dApps.

Web3 APIs are a crucial component in the development of decentralized applications, enabling seamless interaction with blockchain networks and expanding the functionalities and possibilities of dApps within the decentralized ecosystem. Next, we’ll take a closer look into SPYCE.5 Web3 APIs and how you can get started on building your first dApp.

Developing dApps with SPYCE.5 Web3 APIs

SPYCE.5 Web3 APIs are built on the next-generation blockchain IOTA providing unparalleled performance, scalability, and security for your blockchain application. IOTA is a DLT (distributed ledger technology) based on a new and revolutionary technology called the Tangle that uses a direct acyclic graph (DAG) consensus algorithm. You can read more about IOTA and the technology in our deep-dive article.

Let’s take a closer look at the key benefits the SPYCE.5 Web3 APIs bring to the table:

Now that you know how you can benefit from using SPYCE.5 Web3 APIs let’s go through some concrete steps to help you get started in building your first dApp.

1. Get your Web3 API Key

To get started and access the Web3 APIs, you must create a SPYCE.5 account.

Once registered, you can have access to your API Key.

1. Log in to your SPYCE.5 account and navigate to the API Key section. Here you can see a list of your API keys.

2. You can manage your API key in the details view. By upgrading your account you can add additional API keys to your account. In our example, you can use your default API key.

The API Keys section lists your API keys

Next, you need a network endpoint to make requests with your API key.

2. Get your endpoint

By leveraging endpoints, you can seamlessly connect your dApp to various blockchain networks, enabling functionality like querying balances, fetching transaction data, or interacting with smart contracts.

To connect to a network through an endpoint, you can follow these steps:

1. First, login into the SPYCE.5 account, and navigate to the Endpoints section.

2. Then select the API Key you are using in your dApp from the dropdown menu and the page will update with your API Key-specific RPC Endpoints.

The Endpoints section lists all network endpoints

Next, we will show you how to create your first Web3 API request in your dApp.

3. Make your first API request on Shimmer

In this step, we assume you have the basic knowledge of building Web2 apps. To implement your Web3 API Key into your decentralized application, you need to follow a few simple steps.

1. First, install the IOTA SDK in your preferred language. The following examples will use node.js but apply to any other language. 

2.  Import the IOTA SDK into your code. Make sure to insert your endpoint URL into the corresponding variable below.

Note: As a best practice, you should not insert your plain API key in the code but use appropriate measurements to protect it.

import { Client } from "@iota/sdk";

const sendBlock = async () => {
  const client = new Client({
    nodes: [
      {
        url: [insert-your-endpoint-url],
      },
    ],
  });
};

3. As your first API request we will create an empty block and print a link to the explorer where the block can be viewed.

const blockIdAndBlock = await client.buildAndPostBlock();
console.log(`Explore created block: https://explorer.shimmer.network/shimmer/block/${blockIdAndBlock[0]}`);

4. To put it all together, the final result should look like this:

import { Client } from "@iota/sdk";

const sendBlock = async () => {
  const client = new Client({
    nodes: [
      {
        url: [insert-your-endpoint-url],
      },
    ],
  });

  const info = await client.getInfo();
  console.log(`Network: ${info.nodeInfo.protocol.bech32Hrp}`);

  const blockIdAndBlock = await client.buildAndPostBlock();
  console.log(`Explore created block: https://explorer.shimmer.network/shimmer/block/${blockIdAndBlock[0]}`);

  client.destroy();
};

sendBlock();
