Is CFCA CryptoKit.Paperless.SINOTRANS Extension safe?

Low risk

CFCA CryptoKit connects to any native-messaging host that sinotrans.com or y2t.com pages name, with no host allowlist.

This extension bridges web pages to a locally installed native app that signs transaction data with a smart card. Any page on the trusted sinotrans.com or y2t.com domains, including over a plain unencrypted http:// connection, can tell it which native host to connect to and what payload to send, and the extension forwards that verbatim without checking the host name against a fixed, expected value. The native app's replies are relayed straight back to the calling page.
