Hedera
Hedera
#Overview
Hedera is an EVM-compatible decentralized, open-source and proof-of-stake Layer1 blockchain. It utilizes the leaderless, asynchronous Byzantine Fault Tolerance (aBFT) hashgraph, offering fast transactions and low fees.
As Hedera is EVM compatible, you can follow the Ethereum documentation to send your first transaction and utilize all other wallet features.
#Installation
Magic interacts with the Hedera blockchain via Magic's extension NPM package @magic-ext/hedera. The Hedera extension also lets you interact with the blockchain using methods from Hedera SDK.
01npm install --save @magic-ext/hedera
#Configure Hedera
ES Modules/TypeScript
01import { Magic } from 'magic-sdk';
02import { HederaExtension } from '@magic-ext/hedera';
03
04const magic = new Magic("YOUR_API_KEY", {
05 extensions: [new HederaExtension({
06 network: 'testnet' // 'mainnet' or 'testnet'
07 })]
08});
#Send Transaction
#Call Extension Method
Note that the Magic Hedera extension follows the method names and conventions by hedera-sdk-js. To send a standard Hedera blockchain transaction, you can call the inject the MagicWallet to hedera-sdk-js. More details please reference to example-hedera github repo.
