Arbitrum published an AIP proposal on the forum about "Account Abstraction Wallet Support RIP-7212".
The proposal believes that the adoption of RIP-7212 will reduce the cost of using Passkey-based wallets on Arbitrum One and Nova, making them more suitable for daily use and enabling DApp developers and protocols to provide users with a better experience. Passkey-based wallets provide better security levels and seamless cross-device support compared to typical EOA.
