The GLP liquidity pool of GMX V1 on the Arbitrum platform has been compromised, resulting in the transfer of approximately $40 million in tokens to an unknown wallet. GMX announced the incident on their Telegram channel, confirming that security partners are actively investigating the breach. In response, both Arbitrum and Avalanche platforms have suspended GMX V1 transactions and halted GLP minting and redemption to prevent further exploitation. Notably, GMX V2 and the GMX token remain unaffected by this vulnerability.
