Failed 2016 Ethereum ICO open 1,003 ETH as preserved refund bug reopen
One white-hat researcher wey dem dey call 0xFlorent help unlock 1,003.62 ETH from HongCoin wey fail their 2016 Ethereum ICO after nine years. For around $1,983 per ETH on June 1, the recovered value na about $1.99 million.
Dem reopen the refund channel through contract archaeology. Even though the main refund logic bin effectively block because accounting mismatch, one older multisig “management” permission path still dey. In coordination with HongCoin original multisig signers, the team make 48 investors fit claim through refundMyIcoInvestment().
The recovery need 41 multisig-signed transactions. Seven small holders fit refund directly without the workaround. On-chain proof from May 29 show say refundMyIcoInvestment() trigger 96 ETH internal transfer, confirm say the claim route don active again.
Traders make una note say this no be general repeatable exploit template for other dormant contracts. E depend on very specific conditions: the original multisig must still dey usable, the bug must still dey reachable inside the permission boundary, and enough value must still dey. This one na responsible recovery case wey show Ethereum early smart-contract design persistence—both risk and sometimes e fit be built-in escape hatch.
Neutral
Dis event fit create one-off flow of ETH from recovered ICO refunds, but di amounts small compared to overall ETH liquidity. Di bigger lesson na technical: e show say some old Ethereum contracts still fit get dormant permission paths, but e no likely make this turn into repeatable pattern across di market. So, short-term price impact on ETH likely limited, and any sentiment effect dey muted because di recovery na responsible and no be exploit.
