96 Private Keys Stolen From Vulcan Forged Crypto Gaming Platform in $140 Million Theft

A hacker who exploited Polygon gaming platform and NFT marketplace Vulcan Forged was able to steal a total of over 4.5 million of the $PYR native token, valued at US$140 million at the time of the December 14 attack. A total of 96 users’ wallets were accessed by the hacker via private keys.

‘Darkest Day in our History’

CEO Jamie Thomson described the situation as “the darkest day in the Vulcan Forged history” in this video posted on the company’s Twitter account:

The hacker was able to attack the Vulcan Forged servers, gaining access to the vending credentials of the semi-custodial wallets and then extracting the private keys of the game’s users. To prevent any repeat of the exploit, Thomson says the platform will in future be using nothing other than decentralised wallets “so we never have to encounter this problem again”.

Full Refunds and a Heartfelt Apology

Refunds have been made to every wallet that had the game’s native $PYR tokens stolen, and Vulcan Forged will also be reimbursing the loss of any Matic and Eth tokens stolen from users. Ending with a sincere apology to the community, Thomson said: “obviously sorry doesn’t cut it, but we are sorry”.


It has been a disappointing outcome for the Vulcan Forged team, not to mention players and investors. $PYR dropped in value by over 30 percent in the 24 hours post the hack.

In a similar incident last month, the bZx DeFi protocol had funds drained from its Binance Smart Chain (BSC) and Polygon contracts after one of the developers had his private key stolen in a phishing attack.
