CROSSx 2.0

CROSSx 2.0 is a next-generation Embedded Wallet SDK platform. It
integrates OAuth-based authentication and blockchain wallet
functionality into a single SDK, enabling app developers to implement
Web3 features without the complexity of key management.

  injection also supported)
• Embedded Wallet - Mnemonic-based HD wallet creation and
  management, protected by PIN
• Signing & Sending - EIP-191 message signing, EIP-712 typed
  data, transaction signing and sending
• RPC Proxy - Chain-specific JSON-RPC calls (eth_call,
  eth_getBalance, etc.)
• Biometric Authentication - PIN protection via Face ID / Touch
  ID
• Legacy Migration - Automatic recovery of existing CROSSx
  native app wallets
