The security model of the Hedera Smart Contract Service has been updated with the mainnet services release v0.35.2 (March 2023). The updated model aligns the behaviors of the Hedera Smart Contract Service token system contracts with those of EVM and typical token APIs such as ERC 20 and ERC 721. Read this article to learn specifically what changed, what it means for developers, and what actions you should take.

In this step-by-step tutorial, you will create a simple counter dApp on the Hedera network using Solidity, React JS, MetaMask, and Ethers JS. The goal with this example is to help you understand the fundamentals of dApp development, making it easier for you to create more complex dApps in the future.

In this tutorial, we'll walk you through the process of connecting to MetaMask using create react app. We'll also guide you through the steps to transfer HBAR to the MetaMask wallet. By the end of this tutorial, you'll have a solid understanding of how to seamlessly integrate MetaMask into your Hedera decentralized application. So, let's get started! 🎉
