Opclave supports transactions with Apple Face ID and Touch ID

Opclave, developed by the Istanbul University İTÜ Blockchain Club team, was shortlisted for the ETHGlobal Scaling 2023 Hackathon. It is an improvement of OP Stack for ERC-4337 compatible smart contract accounts. The smart contract wallet uses signatures abstracted from Apple Enclave, allowing users to create and use Apple Face - Non-custodial wallet for ID and Touch-ID without seed phrase. Its core idea is to turn Apple devices, iPhones, and Macbooks into hardware wallets, and initiate transactions from the trusted execution environment Apple Secure Enclave to ensure security. At the same time, Opclave also has functions such as social recovery, batch processing, support for ERC20 token payments, and daily spending limits. After that, the team will also develop other account abstraction features such as 2FA, email login, and support for other chains such as Starknet, zkSync, Fuel, etc.
