#Installation
To get started, install the following dependencies for your project:
NPM
Yarn
01npm install @magic-ext/solana @solana/web3.js magic-sdk
#Initialization
The Magic class is the entry-point to the Magic SDK. It must be instantiated with a Magic publishable key.
#ES Modules/TypeScript
Typescript
01import { Magic } from 'magic-sdk';
02import { SolanaExtension } from '@magic-ext/solana';
03
04const magic = new Magic('YOUR_API_KEY', {
05 extensions: [
06 new SolanaExtension({
07 rpcUrl: 'SOLANA_RPC_NODE_URL',
08 }),
09 ],
10});
#CDN
Javascript
01<script src="https://auth.magic.link/sdk"></script>
02<script type="text/javascript" src="https://auth.magic.link/sdk/extension/solana"></script>
03
04<script>
05 const magic = new window.Magic("YOUR_API_KEY", {
06 extensions: [
07 new SolanaExtension({
08 rpcUrl: 'SOLANA_RPC_NODE_URL'
09 })
10 ]
11 });

#Common Methods
Note that the Magic Solana extension follows the method names and conventions by Solana's Javascript SDK.
#Sign and Send Transaction
#ES Modules/TypeScript
To sign a standard Solana blockchain transaction, call the magic.solana.signTransaction method. Note that you must sign with the Magic SDK method but send the transaction using the @solana/web3.js method connection.sendRawTransaction.
Typescript
01import * as web3 from "@solana/web3.js";
02
03// Ensure you have Magic initialized with the Solana extension
04// Ensure that user is already authenticated
05
06const connection = new web3.Connection(clusterApiUrl("devnet"))
07
08const metadata = await magic.user.getMetadata();
09const userPublicKey = new web3.PublicKey(metadata.publicAddress);
10const recipientPubkey = new web3.Keypair.generate().publicKey;
11
12const blockhash = await connection?.getLatestBlockhash();
13if (!blockhash) return;
14
15const transaction = new web3.Transaction({
16 ...blockhash,
17 feePayer: userPublicKey,
18}).add(
19 web3.SystemProgram.transfer({
20 fromPubkey: userPublicKey,
21 toPubkey: recipientPubkey,
22 lamports: web3.LAMPORTS_PER_SOL * 0.01,
23 })
24);
25
26const signedTransaction = await magic?.solana.signTransaction(
27 transaction,
28 {
29 requireAllSignatures: false,
30 verifySignatures: true,
31 }
32);
33
34const signature = await connection?.sendRawTransaction(
35 Buffer.from(signedTransaction?.rawTransaction as string, "base64")
36);
37
38console.log(signature);
#Sign Message
#ES Modules/TypeScript
Typescript
01// Ensure you have Magic initialized with the Solana extension
02// Ensure that user is already authenticated
03
04const signedMessage = await magic?.solana.signMessage("Hello World")
05
06console.log(signedMessage)
