White Hat Hacker Rescues $2 Million in Stuck Ethereum From 2016 ICO
Imagine waking up to find out that money you lost in a failed cryptocurrency project nearly ten years ago is suddenly sitting back in your wallet. That is the reality for dozens of crypto investors right now, thanks to a security researcher who figured out how to unlock a digital vault that had been broken since the early days of Ethereum. A pseudonymous white-hat hacker known as 0xflorent recently recovered 1,003 Ether (ETH)—worth over $2 million today—that had been trapped inside a faulty smart contract for nearly a decade.
The funds belonged to 48 investors who participated in the initial coin offering (ICO) for Hong Coin (HONG) back in the summer of 2016. Pitch videos from the time show that Hong Coin was meant to act as a community-governed, decentralized venture capital fund. Members of the project’s decentralized autonomous organization (DAO) were supposed to vote on which Web3 startups would receive funding. The token sale launched on August 29, 2016, and wrapped up two months later on October 28. Unfortunately, the project never quite caught on and failed to reach its minimum funding goal, meaning it was dead on arrival.
A Stalled Automated Refund and a Decade-Long Freeze
Under normal circumstances, a failed ICO shouldn’t mean lost money. The smart contract was explicitly programmed to automatically return everyone’s Ethereum if the project didn’t raise enough capital. However, coding a smart contract in 2016 was uncharted territory, and a subtle bug in the code quietly broke the automated payout mechanism. Instead of sending the crypto back to its rightful owners, the contract permanently locked the funds. For almost ten years, the capital sat completely untouched and unreachable on the blockchain.
Blockchain data shows that the rescue mission is already actively paying out. One early Hong Coin investor has already received a massive refund of 96 ETH, which translates to roughly $192,500 at current market prices. Another smaller participant has successfully reclaimed 0.5 ETH. While the creators of Hong Coin originally wanted to do right by their community, they simply lacked the technical means to bypass their own locked contract until an expert took a closer look at the code.
Breaking the Smart Contract to Get the Capital Out
The breakthrough happened when 0xflorent reached out to the original Hong Coin developers to collaborate on a fix. Instead of looking for a traditional back door, the hacker analyzed the contract’s administrative settings and discovered an unexpected flaw: an integer overflow vulnerability inside an old admin function. In blockchain programming, an integer overflow occurs when a number exceeds its maximum storage capacity, causing the value to wrap around to zero or a negative number.
By executing this specific admin function with a highly precise, calculated input, 0xflorent managed to trigger the glitch on purpose. The exploit reset the token holders’ balances to zero, which effectively tricked the broken smart contract into bypassing its frozen logic and unblocking the refund checks. This isn’t the first time 0xflorent has pulled off a tricky digital rescue; the same researcher recently recovered over 19 ETH for a failed 2018 project and a Liquality Wallet user whose funds were jammed in a cross-chain transfer protocol. It is a stark reminder that while early code is brittle, ethical security researchers are capable of fixing even the oldest mistakes on the blockchain.
