Seed phrase leak pumps memecoin to $14M, Exposing crypto’s copy-trade risk

An exposed recovery phrase of a Robinhood co-founder made it possible for a hacker to convince thousands of traders to join one memecoin instantly, proving that herd mentality can rapidly change the crypto market. The incident did not affect Bitcoin or Ether, but it revealed a weakness across the entire crypto market: traders on any platform blindly follow large wallets, and this can be turned into a weapon if that wallet is compromised. Within the span of about two hours, the token named “$1” increased in value from $500,000 to $14 million before undergoing a correction, accumulating a trading volume in excess of $20 million. The attack was shared by Michael, the Chief Business Officer of TokenPocket wallet, who summarized how things unfolded that night in a series of posts on X on July 13. According to Bitget, a crypto data platform, quoting the same source, this event is a coordinated pump and dump scheme. How one wallet moved a market Michael says it was not a hack, but rather an error that led to the breach. He claims the mnemonic phrase – a sequence of words that is used to access a self-custody wallet belonging to the founder – was accidentally shared during a live broadcast on Wednesday. This means that anyone tuning in who managed to note it down could access a wallet containing about $1.5 million. 昨晚可能有兄弟睡早了，不知道发生了什么事情，我给刚起床的兄弟梳理一下这精彩的一夜。昨晚，黑客盗了Robinhood创始人的地址后，做了2件事情： 1. 用这个地址及其关联地址买 $1 代币，导致几千人跟风，一下子把 500K 市值的币拉到了 14M，随后暴跌，2小时交易量就达到了20M 美金。 2.… pic.twitter.com/XJlctMSZtm — Michael (@0xMichael) July 13, 2026 The attacker was the first to arrive at the address. Now that it had taken over the address, the assailant moved to begin acquiring the “$1” token. Onlookers monitoring the wallet interpreted this acquisition as a gamble by Robinhood’s founder and quickly made their own investments, leading to an increase in the token’s market value by almost 28 times before the buying activity came to an end and the price began to decline. Late investors thus suffered losses. Why the freeze came too late for traders Michael stated that Robinhood’s remote procedure call (RPC) service, the software that relays transactions to the network, blocked the hacked address. The nodes using the RPC service stopped processing transactions sent from the wallet, effectively preventing the hacking event from draining the contents of the wallet. The action to contain does not help those individuals who purchased the “$1” cryptocurrency when the price was near the maximum level. Nevertheless, the freezing of a wallet means that no transactions can be made in the future, but trades made previously on decentralized platforms remain. While the block was being implemented, the criminals moved to different platforms.
