Optimism, an Ethereum layer 2 solution, is poised to release approximately $81 billion worth of OP tokens on January 29, 2024. This unlock, involving over 24 million OP tokens, represents about 2.5% of the circulating supply and is part of a strategy to gradually release tokens to investors and contributors. Despite the potential market impact, Optimism continues its growth with recent upgrades and a $30 million token distribution initiative for community contributors.
