The attackers also tried to steal around 80 BTC and 6,500 ETH (currently worth over $12.6 million) from a cold wallet belonging to Stephens, but were thwarted by an email alert sent to Blockchain Capital employee.
A bridge between Ethereum and the Shibarium network was released as the network went live, and eager users quickly transferred a combined 954 ETH (~$1.7 million) to the bridge contract so they could access it on the new chain. However, users started reporting that transactions were stalled, and they weren't able to access their tokens on the Shibarium side.
The team quickly shut down conversation on Discord as more issues were raised, and claimed in a blog post that the issues were caused by nothing more than the network being overwhelmed with traffic. The team denied the authenticity of screenshots of a Telegram chat appearing to show the lead developer writing that the funds were unrecoverable, insisting they were safe.
Finally, weeks after the botched launch, Shibarium re-enabled the bridge and told users they could once again access their funds. Though there have been some delays in transactions, the "stuck" funds appear to be retrievable.
SwirlLend was a lending protocol operating on both Base and the similarly newborn Linea chain. Shortly after its launch, the project drained a combined $460,000 from the two chains, then deleted its social media accounts.
Prime Trust is a crypto custodian that previously served companies including Binance US, Swan Bitcoin, and BitGo. Just a year ago, the company announced they had raised $100 million in a Series B funding round, and planned to add crypto retirement accounts to its list of products. It's probably a good thing that didn't pan out.
According to bankruptcy documents, Prime Trust has between $50 million and $100 million in assets, but between $100 million and $500 million in liabilities. They report having between 25,000 and 50,000 creditors.
RocketSwap later announced a plan to airdrop tokens to "compensate" users for the theft. They also tried to reassure projects that were migrating away from RocketSwap that there was "no need to run away, your funds are safe".
The attack was a "classic price manipulation" exploit, according to the Ironblocks security firm. The attacker was able to steal 1,152 ETH ($2.13 million) from the protocol. They then tumbled the stolen funds through Tornado Cash.
Lin had created a project called "FrensTech", which aimed to capitalize on the popularity of a product called "friends.tech", and which ultimately accumulated the 14 ETH in fees before he decided to drain liquidity. Lin had not tried to conceal his identity. After the rug pull, Uniswap founder Hayden Adams wrote on Twitter: "Wanted to let people know this person is no longer with the company. Not behavior we support or condone."
Lin was unapologetic, tweeting: "got fired from uniswap, but gained 600 new followers and [crypto Twitter] villain status. net neutral tbh".
SpiritSwap was previously one of the most popular DEXes on Fantom, boasting an all-time-high of $374 million in January. It now has less than $3 million TVL, thanks in part to the Multichain collapse and to the broader cryptocurrency bear market.
SpiritSwap is only the most recent project to announce its closure as a result of the Multichain fiasco. In July, Geist Finance and Hector Network also announced they would be shutting down due to Multichain contagion.
Nevertheless, when Distrust disclosed this to Libbitcoin, the team replied first that they were too busy, then twice that "they do not feel this is a bug".
The research team has not yet disclosed which wallets were affected by the vulnerability, but they have estimated that around $900,000 were stolen as a result.
