Kraken has filed suit against PowerTrade, a crypto derivatives firm, claiming the platform made unauthorized corrections to the exchange's account that erased roughly $9 million in value, according to the legal filing.
PowerTrade allegedly changed Kraken's balance from a positive $7 million to a $2 million deficit through a series of corrections linked to trades that had already expired or settled months prior. The filing does not specify which court is hearing the case or what relief Kraken is seeking.
The core dispute hinges on settlement finality. Once a trade settles, reversing it typically requires consent from both parties. PowerTrade's ability to unilaterally correct old settlements—even if framed as fixing errors—strips away that finality and leaves a counterparty vulnerable to surprise balance swings long after a transaction should be closed.
This type of friction is not unique to PowerTrade or Kraken. Derivatives platforms, especially those handling off-chain settlement or hybrid models, often disagree with clients over what constitutes a legitimate correction versus a misappropriation. The risk grows when one platform has unilateral authority over settlement records and the other has limited visibility into the transaction history.
Neither Kraken nor PowerTrade has publicly commented on the lawsuit. The case will likely turn on whether PowerTrade had contractual grounds to reverse the settled trades and whether Kraken had notice of or agreed to those reversals.
