A hacker compromised the official X accounts of SpaceX and Starlink to promote a memecoin on the newly launched Robinhood Chain. The token's value spiked to a $2 million market cap before its creators abruptly withdrew liquidity, leaving investors with worthless assets.
The incident occurred just days after Robinhood's Layer-2 blockchain mainnet went live on July 1, 2026. The security breach exploited the trusted platforms to drive speculative trading.
Data from the chain's first week shows over 75% of trading volume came from memecoins, with the total memecoin market cap briefly exceeding $244 million. One token, CASHCAT, saw reports of associated phishing and hacking attempts.
Robinhood CEO Vlad Tenev's social media activity during the launch was noted as amplifying interest. The chain attracted nearly $79 million in total value locked, predominantly fueled by memecoin speculation.
The sequence of rug pulls and security issues in the first week raises concerns for institutional investors about ecosystem safety. It creates a critical question for Robinhood's crypto strategy: whether the memecoin dominance is a temporary launch phase or a defining characteristic of its user base.
