Phantom (phantom.app) is the most widely used self-custodial wallet for Solana, available as a browser extension for desktop browsers and as a mobile application on iOS and Android. It is the primary interface through which most Solana meme coin traders interact with the blockchain — signing transactions, managing token holdings, connecting to trading applications, and displaying portfolio values.
Core functionality
- Stores SOL and all SPL tokens (the Solana token standard)
- Signs transactions for all Solana dApps including pump.fun, Jupiter, and Raydium
- Built-in swap functionality (powered by Jupiter)
- NFT display and management
- Multi-wallet management — create multiple wallets within one Phantom installation
- Hardware wallet integration (Ledger)
Security considerations
Phantom is a "hot wallet" — the private keys are stored on the device and connected to the internet, which is necessary for convenient transaction signing but creates security risks. For significant holdings, hardware wallets provide better security. Common attack vectors against Phantom users include phishing sites, malicious dApp connections, and seed phrase theft. See the Wallet security guide for detailed protection strategies.
Phantom and multi-chain
Phantom has expanded beyond Solana to support Ethereum, Bitcoin, and other chains. For most memecoin traders, the Solana functionality remains the core use case.
