Decentralized exchange dYdX is poised to unlock tokens, equating to 30% of its total allocation for investors, founders, and staff, on December 1 at midnight UTC. These tokens are currently valued at $500 million. This move follows dYdX's price surge after delaying the unlock from February to December. The exchange also faced a $9 million blow to its insurance fund recently, described as a "targeted attack" by its CEO.
