Doja Cat's Twitter account was hacked to promote a Solana-based meme coin, causing her to quickly inform her followers on Instagram that she was not responsible for the posts. The hacker made over two dozen tweets, removed Doja Cat's profile picture and description, and mentioned other celebrities like Iggy Azalea. The $DOJA token, housed on Solana's Raydium, had relatively low activity with around 15,000 transactions and $2.2 million in volume.
