Getting Started

This quickstart is tailored for developers eager to connect with and explore the capabilities of the Stability Testnet and Global Trust Network (GTN) directly. This guide is designed for developers aiming to craft decentralized applications (dApps), enthusiasts keen on engaging with Stability's blockchain, and anyone interested in understanding what sets Stability apart from traditional EVMs and smart contracts.


This tutorial presumes a foundational understanding of blockchain technology and familiarity with tools that interact directly with the blockchain. For example, smart contracts and development tools such as Remix and Viem.

Register for an API Key

Global Trust Network (GTN) and Stability Testnet employ API keys to manage transactions. On Global Trust Network, an API key is required to perform write transactions. On Stability Testnet, each address is given a limited number of free transactions without an API key using our public RPC. To increase the number of transactions that a certain user can execute on either chain, users are required to sign up with our Account Manager for their very own private RPC address.

2. Sign Up For An API Key

Step 1 - Navigate to Stability Portal and click the `Login | New User' button.

Step 2 - Select Your Preferred Registration

On this screen, select your preferred method of registration. For this tutorial, we will be following the Google sign-in path. You may also similarly log in via Email, GitHub, Magiclink, or directly through Metamask.

It is important to note that registrations through Metamask or Magiclink do not provide a dedicated API Key. Without an API Key, you will not be able to perform transactions on Global Trust Network (GTN), and will have limited functionality on Stability Testnet. To receive an API Key, you must register using either GitHub, Google, or Email.

If you opt to register via email, ensure you can verify your email address.

3a. Add Network Automatically to Metamask + Other Compatible Wallets

Metamask Logo

To add your custom RPC to your browser extension wallet, which will allow you to use Global Trust Network or Stability Testnet, click the Metamask Fox Logo next to your API Key. This will work with Metamask as well as many other browser extension based wallets.

If you are not able to add the network to your wallet, you may have to add the network manually. Follow the instructions below.

3b. Add Network Manually to Metamask

In the event you are unable to add your wallet automatically via clicking the Metamask Fox Logo above, or you wish to add the network manually, simply follow the steps below.

Step 1 - Navigate to Settings in Metamask.

4. Review What Is Different With Stability

We highly recommend reviewing the section on What Is Different regarding Stability as opposed to traditional Ethereum Virtual Machine (EVM) blockchains. Understanding these distinctions is crucial for developers looking to create decentralized applications (dApps) on the Stability platform, especially since certain functionalities, like native token transfers, will not operate in the same way on Stability.
