Kabosu’s owner didn’t know what to expect when he announced his new Shiba Inu dog, Neiro, on Sunday, even though he had officially said he would stay away from such tokens.

Kabosu is known for being the owner of the dog photo that inspired the Dogecoin (DOGE) meme and subsequently gave birth to the $37 billion dog-themed memecoin industry, which includes Shiba Inu (SHIB), Floki (FLOKI), and others. Kabosu passed away in May at the age of 17, leaving behind a statue and an $18 billion memecoin.

Kabosumama, the owner of the popular Shiba Inu dog that inspired Dogecoin, adopted Neiro, a ten-year-old Shiba Inu dog, last week, calling him his “new family member.”

Initial responses to this announcement were full of support for the new pet, but it soon became a promotional fest for NEIRO tokens, with people launching tokens on Solana using the likes of Neiro.

Hundreds of Neiro or Neiro-themed tokens were issued on Solana token maker Pump Fun, with one of them quickly gaining a market cap of tens of millions of dollars. Some traders then discovered that the token with a market cap of $100 million was the most popular, while the other was actually the first token to exist, which changed the dynamics and caused a brief sell-off.

This discovery caused traders to quickly allocate capital to or trade both tokens, resulting in two Neiro-themed Solana tokens—the two garnered a combined trading volume of $340 million.

This put Solana ahead in total blockchain activity on Monday, with on-chain volumes often seen surpassing the leader, Ethereum. According to DefiLlama data, Solana collected $1.8 billion in trading volume each on Sunday and Monday, whereas Ethereum’s trading volume remained below $1 billion.

Therefore, the price pump of the more popular NEIRO token netted its founder at least $5.4 million in profit, on-chain analysis tool Bubblemaps noted in an X post.

The founder purchased a large portion of the token shortly after it went live using several wallets and sold it as the token went viral. Both NEIRO tokens are actively traded and listed on exchanges as of Tuesday. Each community calls itself real and aims to repeat the success of Dogecoin.

According to Neiro’s owner, Kabosumama, none of the tokens are legitimate.

“I see a lot of tokens related to Kabosu and Neiro. To clarify, I do not support any crypto project other than ownthedog $dog because they claim the original Doge photo and IP,” he said in an X post. “They make a commitment every day to just do good and focus on charity and the Doge culture.”
