The session management mechanism of WalletConnect has hidden risk resistance designs:
Traditional connection protocols continue to be valid once a session is established, which poses a risk of being hijacked. However, it adopts a "time-sensitive session key" system, where the temporary key generated for each interaction is only valid for 15 minutes and supports real-time manual revocation by the user.
Even more sophisticated is the "multi-device synchronization" feature. When the user confirms a transaction on the mobile wallet, the DApp on the computer will simultaneously display the encrypted verification code, eliminating man-in-the-middle attacks through cross-device secondary verification. This dynamic security strategy has kept the incidence of connection security events over the past three years below 0.003%, far lower than the industry average.
