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.

Explore the concept of Maximal Extractable Value (MEV), including a real-world example, MEV’s implications on ecosystem stakeholders, and how Hedera is natively resistant to MEV behavior by using its unique consensus mechanism and fixed-fee economics.

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! 🎉

Hedera is committed to setting the industry standard for transparency, reporting, and business process maturity. We operate in a dynamic environment and fast-changing landscape, and the Council will be reviewing and evolving our reporting methodology over time.

On Thursday, March 9, an attacker exploited the Smart Contract Service code of the Hedera mainnet to transfer Hedera Token Service (HTS) tokens held by certain DEXs’ accounts to the attacker’s own account. The following is a summary of the attack: how it happened, steps taken to pause the attack and then permanently prevent it from happening again.

We believe that no honest count of transactions should include 'how we internally came to consensus on the order of whatever volume of transactions were submitted by external parties’, however that might be done on different ledgers.

Guardian is a policy engine that links together tokenized digital environmental assets like carbon offsets, emissions, and RECs (Renewable Energy Certificates) to the physical reporting, identity, and documentary data that substantiates their creation.

At the 2023 Davos “the Future of Emissions” panel, thought leaders converged to tackle the pressing challenge of reducing carbon emissions and creating a more sustainable future by adopting viable ESG efforts.
