How to Integrate with the Hedera Blockchain with Magic
#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.

#NPM
Bash
01npm install --save @magic-ext/hedera
#Yarn
Bash
01yarn add @magic-ext/hedera
#Initializing Extension
#ES Modules/TypeScript
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.
