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。

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. According to Michael, they have moved to the BNB blockchain, created a new cryptocurrency, and practiced wash trading, which means buying and selling the same tokens to create the illusion of demand, to inflate its volume and cash out.

The memecoin trigger

The exact loss here is small compared to the broader market. Bitcoin was valued at almost $62,800 and Ether at approximately $1,778 on July 13, with both being slightly down on that day but unaffected by this meme coin. What makes this event worth examining beyond one token is its underlying processes which are applicable on a greater scale.

Wash trading and pump-and-dump operations represent the most common types of manipulation that occur on-chain. Suspected wash trading has amounted to about 2.57 billion dollars in trading volume across the blockchains that have been researched by the company in 2025, a figure that was derived using matching trades instead of proving the intention behind trades.

The “$1” run fits this model: it generates signals, relies on a crowd believing in the legitimacy of a wallet without verification, and exits through a different chain.

The lesson on self-custody is actually provided by Robinhood itself. In its guidebook about recovery phrases, it states the fact that a set of words is the only way to recover a non-custodial digital wallet and warns people against sharing them, as this enables someone to access the account with the funds. Streaming is one of the most public ways in which sensitive information can be revealed.
