Mantra Hack

On April 13, 2025, Mantra’s OM token crashed by over 90%, wiping out more than $5.5 billion in market cap. The event appears to be a coordinated insider dump rather than a technical smart contract exploit.

The price collapse began after suspicious on-chain activity showed over 43 million OM tokens—roughly 4.5% of the circulating supply—being sent to exchanges like OKX just days prior to the crash. A particularly large transfer of 14 million OM was identified, further fueling speculation of insider involvement. Although Mantra co-founder JP Mullin denied any wrongdoing and claimed centralized exchanges liquidated OM margin positions irresponsibly, blockchain data suggests otherwise.

The OM token had recently undergone changes in emissions and tokenomics, which may have enabled early investors or insiders to unlock and sell significant volumes. The Mantra team insisted that team wallets remain locked, yet failed to provide clear evidence absolving themselves. While the price partially recovered to $1.10, the scale and suddenness of the drop raised red flags across the crypto community, prompting comparisons to the Terra collapse and triggering calls for deeper scrutiny of token transparency and centralized exchange practices.
