The project #Opclave , which was shortlisted for the ETHGlobal Hackathon, provided a solution:
The core idea is to turn Apple devices, iPhones, and Macbooks into hardware wallets, initiating transactions from the trusted execution environment Apple Secure Enclave to ensure security. This biometric wallet not only simplifies the process of using the wallet, but also migrates the transaction experience from Web2 to Web3, which can increase the number of reuses by users and attract more loyal users.
