Optimism, a layer 2 network built on the Ethereum network, has announced its third OP token airdrop, worth $26 million, to 31,870 addresses that participated in delegation activities of its DAO, the Optimism Collective. The rewards were based on the number of tokens delegated by a user and the duration for which they were held. A minimum threshold of 18,000 units was set, and to ensure a fair distribution, rewards were capped at 10,000 OP tokens for each address. The airdrop was aimed at increasing engagement on the platform and rewarding user participation.
