Phantom Connect SDK overview

The Phantom Connect SDKs let your app authenticate users with Google or Apple and automatically create embedded wallets. Users who already have the Phantom extension can also connect with their existing wallet, without creating a new embedded wallet.

​

Prerequisites

All SDKs require that you sign up for an account in Phantom Portal:

1. Sign up at Phantom Portal.
2. Register your app.
3. Configure allowed domains and redirect URLs.
4. Get your App ID.

Security models

All Phantom Connect SDKs are built with enterprise-grade security:

• Trusted Execution Environments (TEEs) for secure operations
• Hardware Security Modules (HSMs) for key encryption
• Multi-layer encryption with threshold cryptography
• Cryptographically signed audit trails for compliance
• Organization-based access control with configurable policies

​

Transaction security for embedded wallets

All transactions signed for embedded wallets pass through Phantom’s advanced simulation system before execution. This security layer:

• Simulates transactions before they’re broadcast to detect potential threats
• Automatically blocks malicious transactions that could drain funds or exploit vulnerabilities
• Blocks transactions from origins that have been reported as malicious
• Provides an additional layer of protection for your users’ assets

​

Multi-chain support

All Phantom Connect SDKs support multiple blockchain networks:

• Solana (Mainnet, Devnet, Testnet)
• Ethereum (coming soon)
• Polygon (coming soon)
• Base (coming soon)
• Arbitrum (coming soon)
• Bitcoin (coming soon)
• Sui (coming soon)
• Monad (coming soon)
