Aptos Labs has launched Petra Vault, a new multi-signature wallet solution on the Aptos network, aimed at enhancing security for both teams and individual users. Petra Vault is compatible with existing multi-signature platforms like Rimosafe and MSafe, allowing users to import vaults without resetting governance. The wallet features a transaction simulation function to preview outcomes before broadcasting, reducing risk. It also supports Aptos Keyless, enabling signature permissions to be distributed across platforms such as Ledger, Google, and Apple accounts. Additionally, Petra Vault offers preset proposal templates for common operations, streamlining processes like token transfers and owner updates.
