Summary
`polymarket-client-sdks` was removed from crates.io for malicious code
Details

It appeared to be typosquatting existing crate polymarket-client-sdk (sdks vs sdk) and attempting to steal credentials from local files.

The malicious crate had 1 version published on 2026-02-09 and had been downloaded only 33 times. There were no crates depending on this crate on crates.io.

Thanks to Roland Peelen for finding and reporting this to the crates.io team!
