How to Integrate with the Terra Blockchain with Magic
How to Integrate with the Terra Blockchain with Magic
#Installation
Magic interacts with the Terra blockchain via Magic's extension NPM package @magic-ext/terra. The Terra extension also lets you interact with the blockchain using methods from Terra's Javascript SDK.

#NPM
Bash
01npm install --save @magic-ext/terra
#Yarn
Bash
01yarn add @magic-ext/terra
#Initializing Extension

Typescript
01import { Magic } from 'magic-sdk';
02import { TerraExtension } from "@magic-ext/terra";
03
04const magic = new Magic('YOUR_API_KEY', {
05 extensions: [
06 new TerraExtension({
07 rpcUrl: 'TERRA_RPC_NODE_URL',

#Sign Transaction
Note that the Magic Terra extension follows the method names and conventions by Terra's Javascript SDK. To sign a standard Terra blockchain transaction, you can call the follow the doc.
