According to BlockBeats, on October 7, MEME tokens themed around cryptographer Len Sassaman have begun to flood the Solana, Ethereum, and Bitcoin networks over the past week. Polymarket bettors speculate that Sassaman might be the pseudonymous creator of Bitcoin, Satoshi Nakamoto.

Last week, speculative traders issued LEN tokens on Solana and Ethereum, with the market capitalization reaching millions of dollars before the gains gradually diminished. Another LEN token, issued over four months ago and claiming to be the first token on Solana, saw a price surge later in the week, surpassing $1.6 million by Monday.

Some individuals have even created MEME tokens centered around Sassaman's cat, SASHA, while others claim another cat, ODIN, was Sassaman's first pet, as noted by his wife, Patterson, on her blog. The market capitalization of SASHA tokens on Ethereum and Solana has exceeded $5 million over the past week. Cryptocurrency users have contacted Patterson on X to inquire about the MEME tokens, receiving a Solana address in exchange for token donations.
