Accounting firm BDO, which recently signed off on reserves reports for Tether, on Friday said it is reconsidering its work for crypto companies.

“In common with several other professional service firms, we are currently evaluating our approach to this sector and the work we undertake for our clients,” a spokesman for the BDO international network said. The spokesman declined to comment on any individual company. The Tether attestation was undertaken by BDO Italia, the Italian member firm of BDO.

BDO's statement follows the news that global accounting firm Mazars, which published several “proof of reserve reports” for digital-asset platforms, is pausing its work with cryptocurrency clients worldwide.
