Gamma, the liquidity management agreement, has announced that it has closed all public treasury/virtual machine monitoring deposit channels. The deposit channels will remain closed until the team discovers and resolves the issue, as users need to withdraw funds. Earlier, there was a flash loan attack on the Gamma Strategies contract on the Arbitrum chain. The attacker manipulated the price and obtained 1535 ETH (valued at approximately 3.43 million US dollars) and bridged it to Ethereum.
