Building on Hedera Course

The Hashgraph Association along with Swirlds Labs launched the Building on Hedera Course – a Course by The Hashgraph Association. The course provides engineers an entry point to the world of Web3 development on Hedera.

Tutorial: MetaMask Snaps – What Are They and How to Use Them

A step-by-step tutorial on how to integrate the Hedera Wallet Snap by MetaMask into a dApp.

DeRec Protocol: A Technical Description

Learn about the different sub-protocols of DeRec. Decentralized recovery (DeRec) is a method of safeguarding a user's secret by distributing shares of that secret among multiple helpers, who store their individual share on their local device in order to help the user recover that secret in future.

How to Setup Foundry and Write a Basic Unit Test

Learn how to set up Foundry and use the Forge command-line tool to run your smart contract tests written in Solidity.

HIP Conversations

HIP-859: Add support for gasConsumed field in REST APIs related to contract results

This HIP will add a new field gas_consumed to the mirror node contract result REST APIs, which will contain the actually consumed gas by the EVM.

HIP-857: NFT Allowances REST API

This is a HIP for adding the ability to query the allowances on NFTs from the mirror node.

HIP-844: Handling and externalisation improvements for account nonce updates

This HIP introduces rules for when to update an Ethereum transaction signer’s nonce and a new field for externalising the nonce update in the record stream.

Adopt Calendar Versioning Schema (CalVer) for hashgraph/hedera-services repository

This HIP proposes to transition the hashgraph/hedera-services repository versioning schema from Semantic Versioning (SemVer) schema to Calendar Versioning (CalVer) with an approach modeled similarly to the Ubuntu Release Cycle that is compatible with most of the rules and priniciples that SemVer provides.

Allow SUPPLY key to adapt metadata of an NFT in the treasury wallet

This HIP is being created to separate the METADATA key HIP and the SUPPLY key adaptation idea into two smaller scoped HIPs instead of all changes going through one HIP.
