Arbitrum has activated account abstraction endpoint support on One and Nova.

BlockBeats reported on August 2nd that Offchain Labs has officially activated support for account abstraction endpoints on Arbitrum One and Arbitrum Nova. Previously, on July 17th, the Arbitrum proposal AIP-2 was voted through, which would activate support for account abstraction endpoints on the One and Nova mainnets. This proposal aims to address the issue of bundled transactions in ERC-4337. The new RPC endpoint, eth_sendRawTransactionConditional, will allow users to specify a valid block height and timestamp range when submitting transactions, thereby resolving the issue of potential changes to smart contract account storage between the verification and execution stages.
