CallMask is a web extension wallet developed by Callchain for the Chrome browser. It serves as the primary wallet for interacting with the Callchain System. With CallMask, users have a single wallet instance that works seamlessly with Callchain applications, eliminating the need for multiple wallets within specific applications.

This extension empowers Callchain developers to create decentralized applications (DAPPs) and engage with the Callchain system efficiently. Users can utilize CallMask to initiate transactions for Callchain DAPPs and receive outcomes from these applications. Additionally, the extension injects the Callchain API into the user's website context, facilitating developer interactions with CallMask. For detailed API documentation, users can refer to the CallMask Github wiki.
