H1 — Executive Summary
What is Phantom?
Phantom is a user-first crypto wallet built primarily for the Solana ecosystem. It provides a browser extension, mobile apps, and developer integrations designed to make key management, token swaps, NFTs, and dApp interactions intuitive while maintaining strong security primitives.
Why it matters
- Low-fee, high-speed transactions on Solana make it ideal for NFT and DeFi experiences.
- User experience focuses on onboarding clarity, transaction transparency, and dApp safety prompts.
- Growing adoption across marketplaces and DeFi protocols.
H2 — Product Highlights
Core features
- Seed phrase / hardware wallet support (Ledger, Trezor via bridge).
- Built-in token swap and portfolio overview.
- NFT gallery, collectible previews, and easy listings on marketplaces.
- Phantom Sign-in (connect to dApps) with transaction preview UI.
User flows (brief)
- Install extension or mobile app → Create/import wallet → Explore dApps via Connect.
- Sign transactions with a clear preview showing fees, program calls, and accounts affected.
Design principles
- Clarity over features: show what’s happening on-chain.
- Progressive disclosure: hide advanced settings behind simple defaults.
- Minimize risky defaults; require explicit user consent for program interactions.
H3 — Security & Privacy
Keyguard & Threat Model
Phantom stores private keys locally and integrates with hardware wallets for cold signing. The threat model assumes a potentially compromised host; mitigations include clear transaction previews, origin binding for dApp requests, and optional biometric gating on mobile.
Best practices
- Encourage hardware wallets for high-value accounts.
- Educate users about phishing: always verify site domains and never share seed phrases.
- Limit permissions requested by dApps; offer session-scoped approvals.
Privacy notes
Phantom does not collect seed phrases or store private keys on remote servers. Analytics are opt-in and aggregated to avoid user fingerprinting.
H4 — Developer Integrations
SDK & APIs
Phantom exposes a JavaScript provider for seamless dApp integration—allowing connection flows, transaction signing, and message signing. Developers should always request minimal permissions and provide clear human-readable transaction descriptions.
Integration checklist
- Implement connection using the recommended provider handshake.
- Provide preflight UI that describes actions and affected accounts.
- Handle user rejections gracefully and surface meaningful error messages.
H4 — Product Metrics & Adoption
Signals to watch
- Monthly active wallets and wallet retention.
- Swap volume and failed transaction rates.
- Number of integrated dApps and hardware wallet pairings.
Growth levers
- Streamline mobile on-ramp and fiat-to-crypto flows (partners & widgets).
- Partnerships with marketplaces to display Phantom-native flows for listings.
H3 — UX Patterns & Accessibility
Transaction previews
Show human-readable summaries, gas/fee estimates, and affected accounts. Use icons and color-coded badges to indicate risk (e.g., program instructions that transfer funds should be highlighted).
Accessibility
Support keyboard navigation, screen reader labels for transaction actions, and clear error text. Ensure color contrast meets WCAG AA for all interactive elements.
H2 — Roadmap & Recommendations
Short-term
- Improve onboarding with guided tours and example transactions.
- Enhance hardware wallet UX for bulk NFT signing flows.
Medium-term
- Fiat on-ramp partnerships and recurring buys.
- Native staking UX and validator integrations for Solana.
Strategic recommendation
Balance product simplicity with advanced controls: maintain a clear path for beginners while exposing advanced features for power users behind additional confirmations.

H2 — Final Thoughts
Positioning
Phantom should be positioned as the user-friendly entry point to Solana — combining polished UX with strong security defaults. For long-term success, focus on onboarding, hardware integrations, and partnerships that bring real utility to users.
