When you look at a crypto project’s tokenomics, you’ll encounter two terms repeatedly: cliff vesting and linear vesting. These are the two fundamental mechanisms that govern how locked tokens are released over time. Understanding the difference — and their impact on token supply — is essential before investing in any project with significant locked supply.
What is Cliff Vesting?
A cliff is a defined waiting period during which zero tokens vest. The recipient holds a future claim on tokens, but receives nothing until the cliff date passes.
Example: A team member receives an allocation of 10 million tokens with a 12-month cliff. For the first 12 months after TGE (Token Generation Event), they receive exactly zero tokens. When month 12 arrives, they either receive their full allocation at once (a pure cliff) or begin receiving monthly releases (a cliff followed by linear vesting).
The cliff serves as a minimum commitment threshold. In traditional equity, it’s common for startup employees to have a 1-year cliff: if you leave in month 11, you receive no vested shares. Crypto projects use the same logic to ensure team members and early investors demonstrate real commitment before receiving any financial reward.
Pure cliff vesting — receiving 100% of the allocation on a single date — is rare for large tranches. It creates a massive supply shock on the cliff date, which is generally bad for token price.
What is Linear Vesting?
Linear vesting distributes tokens in equal proportions over a set period, typically monthly. There is no waiting period — releases begin immediately after TGE (or after the cliff ends).
Example: An investor receives 5 million tokens with 24-month linear vesting starting at TGE. Each month, they receive 208,333 tokens (5,000,000 ÷ 24). The flow of tokens into their wallet is steady and predictable.
Linear vesting is preferred by markets because it creates a known, smooth supply increase. Traders and analysts can model the monthly supply expansion exactly. There are no sudden supply shocks — just a steady cadence of new tokens entering circulation.
Cliff vs. Linear: Side-by-Side Comparison
| Dimension | Cliff Vesting | Linear Vesting |
|---|---|---|
| Release pattern | Lump sum on a single date | Equal amounts each month |
| Supply impact | Sudden spike on cliff date | Gradual, predictable increase |
| Recipient incentive | Strong: must stay through cliff | Moderate: partial value always accruing |
| Market predictability | Low (shock risk) | High (forecastable) |
| Common use cases | Minimum commitment periods | Long-term distribution |
| Typical duration | 6–18 months | 12–48 months |
The Most Common Structure: Linear After Cliff
In practice, most crypto projects combine both mechanisms. The standard structure is:
Cliff period → then linear vesting
For example: 12-month cliff, followed by 24 months of linear vesting.
- Months 1–12: No tokens released
- Month 12: First batch of tokens released (often equal to one month’s linear allocation, sometimes a larger “cliff unlock”)
- Months 13–36: Monthly linear releases until fully vested
This hybrid gives projects the commitment-alignment benefit of a cliff (nobody gets anything for the first year) with the supply smoothness of linear vesting (no single massive unlock date after the cliff).
Impact on Token Supply
Cliff vesting creates supply shocks. When a cliff expires — especially a large team or investor allocation — there is a defined date on which substantial tokens become liquid. If holders sell, order books must absorb significant supply. Projects with multiple large cliffs expiring close together face compounded supply pressure.
Linear vesting creates predictable supply expansion. With linear vesting, the market can price in the monthly supply increase. Each release is small enough that it rarely constitutes a meaningful market event on its own. The “event” is distributed over time.
Worst case scenario: A project where a large VC allocation has a 12-month cliff and then fully unlocks at once (pure cliff, no linear) creates a single date where potentially 10–15% of total supply becomes liquid. This is the highest-risk unlock structure for retail token holders.
Best case scenario: A project where team tokens have a 12-month cliff followed by 48-month linear vesting, and investor tokens have similar structures, means the supply expands slowly and predictably for years. The ongoing buying demand needed to keep prices stable is much lower.
Which is Better for Investors?
From an investor’s perspective, linear vesting is preferable because it:
- Eliminates sudden supply shocks
- Creates forecastable supply expansion that can be modelled
- Distributes sell pressure across many months rather than concentrating it
Cliffs are necessary as commitment mechanisms — but they should always be paired with linear vesting after expiry, not with a full lump-sum unlock.
What to look for when evaluating a project:
- Are cliff dates for large allocations staggered? (Multiple large cliffs expiring simultaneously is a red flag)
- Does the cliff lead to linear vesting or a full lump-sum unlock?
- How large is each monthly linear release relative to current daily trading volume?
UnlockRadar converts all upcoming unlock events — whether cliff expirations or linear monthly releases — into calendar entries with USD values, giving you a clear picture of when supply pressure events occur.
Is cliff vesting good or bad for token price?
Cliff vesting is a double-edged mechanism. The cliff period itself is neutral to positive — no new tokens enter circulation, so there’s no supply-side pressure. However, when the cliff expires, the released tokens can create sell pressure if recipients choose to liquidate. Pure cliff unlocks (100% of allocation released on a single date) are the most dangerous for price. Cliff periods followed by linear vesting are much more manageable — the cliff date releases one month’s worth of linear vesting, and subsequent releases are small and predictable. From a price impact perspective, linear after cliff is significantly better than a pure cliff unlock.
What is linear vesting with a cliff?
Linear vesting with a cliff is the most common vesting structure in crypto. It works in two phases: first, a waiting period (the cliff) during which zero tokens vest — typically 6 to 12 months. After the cliff expires, linear vesting begins: tokens are released in equal monthly portions over the remaining vesting duration. For example, “12-month cliff, 24-month linear” means no tokens for the first year, then 1/24th of the total allocation released each month for the next two years. This structure aligns recipients’ interests with long-term project success while distributing supply expansion smoothly after the initial commitment period.
