How to use Phantom on a mobile browser? (Mobile App)

Accessing Phantom on Mobile Browsers

1. Phantom does not support direct wallet functionality within standard mobile browsers like Safari or Chrome on iOS or Android. The wallet operates exclusively through its dedicated mobile application, which is available for download on the Apple App Store and Google Play Store.

2. Attempting to connect Phantom via a mobile browser’s “wallet connect” prompt will fail unless the Phantom app is installed and properly configured on the device. This limitation stems from how mobile operating systems restrict deep linking and cryptographic key access for security reasons.

3. Once installed, the Phantom mobile app registers itself as a supported wallet with dApps that implement WalletConnect or EIP-6963 standards. Users can then scan QR codes displayed by decentralized applications to initiate secure session handshakes.

4. On Android devices, users may enable “Open links in Phantom” under system settings for supported URI schemes (e.g., solana: or phantom:), allowing certain dApp redirects to launch the app automatically.

5. iOS users must rely solely on QR code scanning due to stricter app sandboxing policies; no automatic redirection or universal link fallbacks are permitted by Apple’s platform guidelines.

Setting Up Phantom Mobile App

1. Download the official Phantom app from phantom.app — avoid third-party stores or APK mirrors to prevent counterfeit versions containing keyloggers or seed phrase harvesters.

2. Upon first launch, choose “Create Wallet” and securely record the 12-word recovery phrase. Phantom never stores this phrase on its servers or transmits it over any network.

3. Set a strong biometric lock (Face ID or fingerprint) and optionally enable cloud backup using an encrypted, user-controlled password — this backup remains inaccessible to Phantom engineers.

4. Import existing Solana wallets by selecting “Import Wallet” and entering the mnemonic or private key. Phantom validates signatures locally before confirming address derivation.

5. Navigate to the “Settings” tab to toggle features such as token auto-detection, transaction simulation warnings, and RPC endpoint preferences for enhanced privacy.

Connecting to dApps via Mobile

1. Open a dApp in your mobile browser that supports Solana wallet integration — examples include Raydium, Orca, Jupiter, or Tensor.

2. Tap the “Connect Wallet” button and select “Phantom” from the wallet list. A QR code will appear on screen.

3. Launch the Phantom mobile app, tap the QR icon in the top-right corner, and align the camera with the code. The app verifies the dApp’s domain and contract permissions before proceeding.

4. Confirm connection request inside Phantom. The app displays the requesting dApp’s name, URL, and requested permissions (e.g., sign transactions, view balance).

5. After approval, the dApp receives a public key and session ID. All signing operations occur locally within the Phantom app — no private keys ever leave the device.

Transaction Signing Workflow

1. Initiate a swap, NFT purchase, or smart contract interaction on the dApp interface.

2. When prompted to confirm, Phantom opens automatically (if already connected) and displays full transaction details including fee estimates, program IDs, and account changes.

3. Review each instruction line-by-line. Phantom highlights suspicious program addresses in red if they match known phishing contracts listed in its real-time threat database.

4. Approve only after verifying destination tokens, amounts, and slippage tolerance. Reject if any field appears obfuscated or mismatched with the dApp’s stated intent.

5. Signature completes instantly using the device’s secure enclave. Transaction hash appears in Phantom’s activity feed and is broadcast to Solana validators via Phantom’s default RPC or a custom node if configured.

Frequently Asked Questions

Q: Can I use Phantom on iOS Safari without installing the app?A: No. iOS prohibits browser-based crypto wallet extensions. Phantom requires native app installation to access secure enclaves and perform cryptographic operations.

Q: Why does my dApp show “Wallet not detected” even after installing Phantom?A: Ensure the dApp uses WalletConnect v2 or EIP-6963-compliant detection logic. Legacy dApps built for desktop-only Phantom injection won’t recognize the mobile version.

Q: Does Phantom store my private keys on its servers when I enable cloud backup?A: No. Cloud backups are encrypted client-side using a password you choose. Phantom cannot decrypt or access those files under any circumstances.

Q: Can I connect Phantom to Ethereum or EVM chains on mobile?A: Phantom currently supports only Solana and associated SPL tokens on mobile. Ethereum chain connectivity remains limited to the desktop browser extension version.
