What is the issue? Some Solana transactions that interact with DeFi protocols like Kamino Finance are causing cost basis loss. This is due to the miscategorization of the "multiple" transaction causing negative balances. As a user, what should I do? You can upvote this forum post to indicate you are experiencing this behavior. The post status will be changed to Complete once a fix is rolled out to all users. Up-voters will be notified of the status change. I need additional assistance, who can I contact? For further assistance, please contact our support team directly.
