Robinhood chain meme token FLYBRAIN briefly reached a market capitalization of $54.61 million before falling to around $30 million, with a six-hour gain of more than 90x, GMGN market data showed. The surge was possibly driven by attention from A16z co-founder Marc Andreessen. FLYBRAIN is based on the fruit fly brain connectome map released by Google and Janelia on September 3, simulating a fruit fly brain by mapping buy and sell activity as sensory inputs and autonomously placing orders to issue tokens.
