API Reference¶

Wallet Store¶

import { useWalletStore } from '@/stores/wallet';

const walletStore = useWalletStore();

// State
walletStore.connected          // boolean
walletStore.connecting         // boolean
walletStore.publicKey          // PublicKey | null
walletStore.wallet             // WalletAdapter | null

// Computed
walletStore.walletName         // string | null
walletStore.walletIcon         // string | null
walletStore.publicKeyBase58    // string | null
walletStore.shortAddress       // string | null

// Actions
await walletStore.connect(wallet)
await walletStore.disconnect()
await walletStore.signTransaction(tx)
await walletStore.signAllTransactions(txs)
await walletStore.signMessage(message)
walletStore.openWalletModal()
walletStore.closeWalletModal()

Solana Composable¶

import { useSolana } from '@/composables/useSolana';

const {
  connection,           // Ref<Connection>
  slot,                 // Ref<number>
  blockHeight,          // Ref<number>
  getBalance,           // (publicKey: PublicKey) => Promise<number>
  getBalanceInSOL,      // (publicKey: PublicKey) => Promise<number>
  requestAirdrop,       // (publicKey: PublicKey, lamports: number) => Promise<string>
  confirmTransaction,   // (signature: string) => Promise<void>
} = useSolana({
  endpoint: 'https://api.devnet.solana.com',
  commitment: 'confirmed',
});

Usage Examples¶

Check Wallet Connection¶

import { useWalletStore } from '@/stores/wallet';

const walletStore = useWalletStore();

if (walletStore.connected) {
  console.log('Connected:', walletStore.publicKeyBase58);
} else {
  walletStore.openWalletModal();
}

Get Wallet Balance¶

import { useWalletStore } from '@/stores/wallet';
import { useSolana } from '@/composables/useSolana';

const walletStore = useWalletStore();
const { getBalanceInSOL } = useSolana();

if (walletStore.publicKey) {
  const balance = await getBalanceInSOL(walletStore.publicKey);
  console.log(`Balance: ${balance} SOL`);
}

Sign and Send Transaction¶

import { useWalletStore } from '@/stores/wallet';
import { useSolana } from '@/composables/useSolana';
import { Transaction, SystemProgram, LAMPORTS_PER_SOL } from '@solana/web3.js';

const walletStore = useWalletStore();
const { connection } = useSolana();

if (!walletStore.connected) {
  walletStore.openWalletModal();
  return;
}

const transaction = new Transaction().add(
  SystemProgram.transfer({
    fromPubkey: walletStore.publicKey!,
    toPubkey: recipientAddress,
    lamports: 0.1 * LAMPORTS_PER_SOL,
  })
);

try {
  const signed = await walletStore.signTransaction(transaction);
  const signature = await connection.value!.sendRawTransaction(
    signed.serialize()
  );
  await connection.value!.confirmTransaction(signature);
  console.log('Transaction confirmed:', signature);
} catch (error) {
  console.error('Transaction failed:', error);
}

Configuration¶

Supported Wallets¶

The wallet integration currently supports:

Phantom - https://phantom.app
Chrome, Firefox, Brave, Edge extensions
iOS and Android apps
Full Solana support
Solflare - https://solflare.com
Chrome, Firefox, Brave, Edge extensions
iOS and Android apps
Staking and NFT support

Adding More Wallets¶

To add additional wallet support, modify src/plugins/wallet.ts:

import { BackpackWalletAdapter } from '@solana/wallet-adapter-backpack';
import { GlowWalletAdapter } from '@solana/wallet-adapter-glow';

export const walletPlugin = {
  install(app: App, options: WalletPluginOptions = {}) {
    const {
      wallets = [
        new PhantomWalletAdapter(),
        new SolflareWalletAdapter(),
        new BackpackWalletAdapter(),  // Add this
        new GlowWalletAdapter(),       // Add this
      ],
      autoConnect = false,
    } = options;

    // ... rest of plugin
  },
};

Network Configuration¶

To change the Solana network, update the composable usage:

// Devnet (default)
const { connection } = useSolana({
  endpoint: 'https://api.devnet.solana.com',
  commitment: 'confirmed',
});

// Mainnet
const { connection } = useSolana({
  endpoint: 'https://api.mainnet-beta.solana.com',
  commitment: 'confirmed',
});

// Localhost
const { connection } = useSolana({
  endpoint: 'http://localhost:8899',
  commitment: 'confirmed',
});

Security¶

✅ Best Practices Implemented¶

No private key exposure - All signing happens in wallet extension
User approval required - Every transaction requires explicit approval
Type-safe - TypeScript prevents common errors
LocalStorage for preferences only - No sensitive data stored
Error boundaries - Graceful error handling throughout
Input validation - All user inputs validated
HTTPS only - Secure communication with Solana network

Browser Compatibility¶

✅ Chrome 90+
✅ Firefox 88+
✅ Brave 1.24+
✅ Edge 90+
⚠️ Safari 14+ (limited wallet extension support)

Troubleshooting¶

Wallet Not Detected¶

Symptom: Modal shows "Not Detected" for all wallets

Solution: 1. Ensure wallet extension is installed 2. Check extension is enabled 3. Try refreshing the page 4. Check browser console for errors

Connection Failed¶

Symptom: Error message when trying to connect

Solution: 1. Ensure wallet is unlocked 2. Check wallet is on the correct network 3. Try disconnecting and reconnecting 4. Clear browser cache and localStorage 5. Reinstall wallet extension if needed

Auto-Connect Not Working¶

Symptom: Wallet doesn't reconnect on page refresh

Solution: 1. Verify autoConnect: true in main.ts 2. Check browser localStorage for walletName key 3. Ensure wallet extension hasn't been updated/reinstalled 4. Try manual connect and then refresh

Summary¶
