DeFi project Wolf has frozen 57% of its token supply, valued at around $13 million, for two years following a security breach. The vulnerability, exploited by a contractor, resulted in a $600,000 loss. In response, an early investor sold off 2% of the tokens. Wolf, under the leadership of CEO Siraaj Ahmed and CTO Robert Freeman from parent company Byrrgis, is adopting 'zero trust' security measures and enhancing vendor controls to bolster system stability and transparency.
