Is Crossmark Wallet safe?

Clean risk

Crossmark Wallet accepts same-page wallet request messages on every HTTP/HTTPS page and forwards them to its background script.

Its content script listens for window.postMessage requests from the current page and passes Crossmark commands such as version, address, network, signing, transactions, encryption, and decryption to the extension. Account details are limited to sites with stored signed-in state, and sensitive signing, transaction, encryption, and decryption requests open the wallet approval UI.
