Leveraging Ethereum Developer Tools On Hedera
The JSON-RPC Relay provides excellent usability for developers with existing workflows dependent on Ethereum developer tools like Truffle, Web3js, Ethers, and Hardhat to seamlessly build on Hedera. In addition, it makes it easy to integrate with Metamask.
How to Send and Receive HBAR Using Smart Contracts – Part 2: Using Solidity
Learn how to send and receive HBAR to and from Hedera contracts. Part 1 of the series focused on using the Hedera SDKs. This second part goes over transferring HBAR to and from contracts using Solidity.
The CREATE2 Opcode on Hedera: An Introduction
The Hedera network provides a powerful decentralized platform, supporting native tokenization, robust smart contracts, and more. HIP-329 introduced the ability to use the CREATE2 opcode on the Hedera network. The power of CREATE2 comes from the deterministic nature of the deployment, meaning the address is easy to compute even before a smart contract gets deployed to the address. Pairing the predictable low fees and scalability of Hedera with the power of the CREATE2 opcode enables users to build incredible user experiences. Read this article for an introduction to the CREATE2 opcode.
Staking on Hedera for Developers – Back to the Basics
In this tutorial, you will learn how to configure staking options for Hedera accounts and contracts programmatically. Perhaps you need to integrate these staking capabilities with wallets, decentralized applications, marketplaces, or other cool things you may be building on Hedera.
How to Send and Receive HBAR Using Smart Contracts – Part 1: Using the SDK
Smart contracts on Hedera can hold and exchange value in the form of HBAR, Hedera Token Service (HTS) tokens, and even ERC tokens. This is fundamental for building decentralized applications that rely on contracts in areas like DeFi, ESG, NFT marketplaces, DAOs, and more. In this tutorial, you will learn how to send and receive HBAR to and from Hedera contracts. Part 1 focuses on using the Hedera SDKs.
Creating Soulbound Token Ecosystems on Hedera
There is a new buzzword in Web3 Identity – “Soulbound Tokens” – a very expressive name for non-transferable non-fungible tokens (NFTs) intended to represent an aspect of someone’s identity, skills, or qualifications. In this posting, we consider what an early implementation of Soulbound Tokens might look like, and how they can be easily implemented on the Hedera network, leveraging the powerful capabilities of the Hedera Token Service (HTS).
How to Set Up Your Own Hedera Local Network Using Docker
The Hedera Local Node is available for developers to start testing and debugging their applications. This article will focus on setting up your local network, starting it, and ensuring that it is operating correctly by submitting transactions and then querying your local mirror node.
Rolling Smart Contract Hedera API Fees into Gas Fees
Core contributors are now focused on an important pricing update for the Hedera Smart Contract service, recently approved by the Coin Committee of the Hedera Governing Council. This update rolls Smart Contract Hedera API (HAPI) fees into gas fees and removes the cover charge for HAPI fees when making a ContractCall transaction.
Anything you can do, you can do on Hedera: Introducing the JSON-RPC Relay
The JSON-RPC Relay makes it easy for existing libraries, development tools, and wallets to work effortlessly on Hedera. Examples include support for wallets, such as Metamask, libraries, such as ethers.js and web3.js, and developer tools, such as Truffle and Hardhat.
Guardian v2.0: The next generation of ESG marketplaces built on Hedera
For Earth Day 2022, Envision Blockchain is proud to announce the release of the 2.0 version of the Guardian. Guardian v2.0 delivers new features to expand on what was built and grow the Hedera Guardian ecosystem.
