December’s unlock calendar is stacked, with large cliff events like Linea alongside steady monthly vesting from Aptos, Arbitrum, and Avalanche. The mid‑month cluster: Sei, StarkNet and Sui adds extra pressure, while Optimism and Polygon close out the year with sizable governance allocations. For traders and long‑term holders alike, these dates are worth marking, as liquidity shifts often translate into price action.
Token unlocks are among the most important events in a project’s life cycle because they directly influence supply, liquidity, and market sentiment. When a large tranche of previously locked tokens is released, it can create immediate selling pressure if recipients decide to liquidate, or it can strengthen confidence if those tokens are held or reinvested. Unlocks also shift the balance of ownership, redistributing supply from insiders and early investors to the broader market. For traders, these dates often mark windows of heightened volatility, while for long‑term holders they signal key milestones in a project’s roadmap. Tracking unlock schedules isn’t just about numbers, it’s about anticipating how supply shocks ripple through price action and community dynamics.
