A cliff wall is a month in which multiple vesting buckets begin unlocking at once, concentrating sell pressure into a single window. It is a core risk our vesting analysis is built to catch and prevent, because a cliff wall can erase a price chart in days.
A cliff wall is entirely preventable. Offsetting one bucket's cliff by two months costs nothing and removes the overlap, yet teams skip the step.
How it works
A cliff wall forms when buckets designed independently all end their lockup at roughly the same time. The investor bucket at 9 months, the ecosystem grant at 10 months, and the team bucket at 12 months look like three separate events.
But their combined release window is only three months wide, and the market begins pricing in the coming supply well before each cliff actually ends. The effective demand shock is compressed even further than the calendar suggests.
Why it matters
On the week a cliff wall hits, circulating supply can jump 5 to 15% in a single month from the combined release. If daily buy pressure has not scaled to absorb that, price adjusts.
A sharp enough adjustment triggers stop-loss cascades and liquidations that amplify the move far beyond the supply addition alone. Across the 2021-2023 cohort of high-profile launches, cliff walls preceded the largest single-month drawdowns on record.
How we approach it
Model every bucket's cliff end date on one calendar before any terms are finalized, then stagger end dates by at least 60 days. If two buckets must share similar cliff lengths for legal reasons, offset one.
In our analysis, cliff walls account for a disproportionate share of post-TGE drawdowns in protocols that otherwise had reasonable individual bucket designs. The aggregate is only visible when someone deliberately builds the combined model.
