According to news on April 21, the Arbitrum community released a proposal on "Passkey-based wallet adopting RIP-7212". The proposal states that adopting RIP-7212 will reduce the cost of using Passkey-based wallets on Arbitrum One and Nova, making them more feasible for daily use and enabling DApp developers and protocols to provide a better experience for users. Passkey-based wallets offer better security levels and seamless cross-device support than typical EOAs.
