Trezor is working with Wasabi for Coinjoins, Wasabi is working with chananalysis companies and it uses to the best of my knowledge from the research I have done, peelchain instead of the recommended ZeroLink, it is advised to verify, do the research and not trust. I have done mine and wouldn't touch Wasabi, nor Trezor after this business deal with Wasabi.

Few articles on the matter:

• https://cryptoslate.com/are-you-exposed-how-chainalysis-cracked-the-wasabi-bitcoin-privacy-wallet/
• https://protos.com/bitcoin-mixing-coinjoin-wasabi-chainalysis-samourai-privacy-wallet/
  • According to Bitcoin developer LaurentMT, anyone interested in tracing Wasabi’s mixed coins could do so without advanced tools. Chainalysis simply used a public flaw in the Wasabi mixing service.
  • Experts have known about a flaw in peelchain-centric designs since July 2019. A member of Samourai described how he could trace 10 BTC ($389,000) through Wasabi’s mixing process.

  • revelations from journalist Laura Shin’s new book The Cryptopians, which tracks Ethereum’s early years, showed that Wasabi failed to follow the aptly named protocol ZeroLink.
  • ZeroLink requires “zero linking” of mixed and unmixed Bitcoin. Wasabi used a ZeroLink alternative called “peelchain.” The wallet was released in 2017
