Optimal vesting structure
Empirical tests by Pantera Capital
Pantera Capital and its partner Lauren Stephanian back-tested tokens performance based on their vesting schedule, in order to empirically come up with the optimal vesting structure. The article is in the link below, but we will report it here as we found it very relevant to our contents and very helpful for the community

The Optimal Token Vesting Schedule Article
Token lockups are a fundamental part of venture funding in crypto. In fact, it’s hard to come by an early-stage crypto company in today’s market that does not have, at minimum, a SAFE / equity note with a token warrant.
From previous analysis in Optimizing Your Token Distribution, we showed that in 2022, on average, around 15% of the total token supply goes to early stage backers of builders in the space - a sizable allocation. But by what mechanism are those tokens distributed to the investors?
Tokens are notably much more liquid than traditional equity, so founders tend to align incentives by implementing a lockup on the tokens that begins after they are generated/distributed. These lockups can range anywhere between 0 days and several years.
We often get asked by founders how long a lockup should be, or we see founders set lockups that seem either too long or too short to properly attract the right investors to their cap table.
Below we’ll be reviewing industry standards by looking into where lockups sit today and how they’ve changed over the past couple of years. We analyzed over 150 data points across 3 funds: Arca, Delphi Digital, and Pantera Capital.
Market Cycles and Funding Terms
The agreements between investors and their portfolio founders have evolved over the years. In the crypto bull run of 2017, the SAFT (“Simple Agreement for Future Tokens”) framework, modeled off of YC’s SAFEs (“Simple Agreement for Future Equity”), was created by Juan Benet, Marco Santori, and Jesse Clayburgh and was released as an open source document available on the SAFT github. They were initially created to do a pre-sale for an ICO at a discount to the public price and were immediately popular; they were adopted by many early protocols, including Filecoin and Kik’s Kin.
However, as time went on, Kik and other protocols faced potential repercussions for allegedly violating securities laws with their ICOs, and SAFTs fell out of fashion. This was exacerbated when 2017’s bull run gave way to an extended bear market starting in 2018, and (non-crypto native) investors - many of whom got carried away in the excitement of the run up in prices - started to question the value of tokens and shifted to preferring equity. During this most recent bull market in 2021, the spirit of the SAFT has made a comeback in the form of token warrants or token rights agreements, but they’re now typically attached to either a SAFE or an equity investment. The big difference is that SAFTs, when used in the current market, are used for projects that have significantly more clarity on token and protocol features, development and launch plans and token launch timelines much closer in time to the fundraise. These are used for a single, identifiable token rather than any possible token that a company may issue, whereas token warrants and agreements are generally used to create value alignment between investors and founders in the latter case
Vesting schedules can be categorized into two different themes: time-based and trigger-based.
A time-based vest (including the cliff) begins at some agreed upon date, either on the date an agreement is executed or a set period of time following the execution of an agreement. A trigger-based vesting schedule is kicked off after some event. Typically this involves a token generation event, but it can also involve a mainnet launch or the listing of a project token on a prominent exchange. We found, around 70% of token vesting schedules were trigger-based and of those, 65% began after a token generation event.
Unfortunately there was a lack of data from 2019 as there weren’t many deals done/recorded in this period, and coincidentally this was the year we started to see more regulatory oversight. In 2020 and beyond, we start to see shorter cliffs combined with longer overall vesting lengths as investors and founders rebound from initial regulatory scares and as founders started to gain leverage leading up to the 2021 bull run.
The deals analyzed had vesting periods ranging from individual blocks, to monthly, to quarterly, to semi-annually. A surprising portion of these deals vested block-by-block, which is a more recent trend, but the bulk - over a third - vested on a monthly basis.
A cliff is a period of time before any tokens are distributed. Cliff lengths in crypto can range from being non-existent to over a year.
Although the data doesn’t reflect it in the graph above, one year cliffs were quite common in vesting schedules in 2018; terms at this time were often verbal or handshake agreements, but were not officially recorded. These one year cliffs were popular for two reasons:
Rule 144 of the Securities Act is the most common “safe harbor” exemption that allows the resale of unregistered securities by an investor without that resale being deemed a distribution on behalf of the original issuer and that investor being deemed a statutory underwriter with associated liability under the securities laws, provided of course that certain conditions are met. One of those qualifying conditions to prevent the resale from being deemed a distribution is that an investor must hold the security for a period of at least one year before any resale. While it doesn’t necessarily impact the lockups per se, the one year holding period helps issuers and resellers comply with securities laws in case the tokens are deemed to be securities later on.
Effects of SEC v. Telegram
The SEC targeting Telegram caused founders to put more time and development into building their protocols, taking care to increase end user, developer, and validator adoption as well as to increase secondary liquidity outside of just the investors themselves. This was to ideally ensure resale at a point in time when the April 2019 SEC factors would point to the token no longer being deemed a security.
Unfortunately there is not conclusive data recorded on whether staking vested and/or unvested tokens was possible. This is typically not written directly into the contract, but some protocols do allow unvested tokens to be staked.
Is there an Optimal Vesting Structure?
With vesting schedules shifting over time, founders and investors alike may ask, “what token vesting structure is optimal?”
We reviewed a number of tokens to test the following hypotheses across linear vests (when the token starts vesting at cliff and then vests by block over a set period of time) and specific date vests (when there are specific dates when the token is released):
Comparing linear to specific date vesting:
Hypothesis A: Linear vests have more volatility over the course of the vesting period than specific date vests
Hypothesis B: Specific date vests have a worse impact on token price at the initial unlock than linear vests
Comparing specific date vests:
Hypothesis C: A higher proportion of tokens unlocked at cliff have a lower impact on token price as a result of foresight into potential token dumping
Hypothesis D: Projects that unlock more each period (and so have fewer total vesting dates) experience better maximum drawdowns than projects that unlock less and have more total vesting dates
Hypothesis E: Projects with longer total lockups experience worse price impacts than tokens with shorter total lockups
The results were as follows:
For specific date vests, 6-month cliffs are preferable to 1-year, or no cliffs
Larger initial unlocks have less negative price impact than smaller initial unlocks
Longer gaps between unlocks (up to 6 months), larger unlocks, and shorter total lockup periods show better ‘worst returns’ than shorter gaps, smaller unlocks, and longer lockup periods
Linear vesting schedules have lower volatility over the vesting period than specific date vesting schedules
Linear vests also showed better impact on price following the initial unlock event than specific date vests
As such, we suggest that founders considering specific date vests over linear vests have a well researched basis for doing so, and founders who still wish to consider specific date vests may consider these findings when determining their vesting structure. Note: this recommendation is based on market effects and preventing volatility, but there may be other important regulatory considerations, such as the Telegram considerations and the possible benefits of complying with the Rule 144 safe harbor framework.
We approached the analysis from a risk management perspective, looking for worst drawdowns rather than maximum positive returns.
We normalized the data using the daily return of the Bloomberg Galaxy Crypto Index (BGCI) as an index. We calculated the token beta over the vesting period and subtracted the daily returns of the BGCI multiplied by the token beta from our token returns to account for different market conditions over time (in other words, we normalized for the token alpha
Where r̂a are the normalized daily log returns of token a, rBGCI are the daily log returns of the BGCI, and 𝛽a is the beta of asset a relative to the BGCI.
The tokens were first split into linear and specific date vests (linear vests typically unlock by block over a specified period), and we then assessed the normalized volatility of tokens across their full vesting period. This was to evaluate the hypothesis that linear vests might cause more sustained volatility in the token over time (hypothesis A).
Our results, ceteris paribus, suggest that there is no clear long-term volatility impact from linear vests when compared with specific date vests; in fact, linear vests demonstrate lower volatility than their counterpart. Additionally, we confirmed our hypothesis that linear vests would have less of an impact on returns at the initial unlock event than specific date vests (hypothesis B).
Next, we compared specific date vests. To start, we assessed the impact of cliff length and initial unlock amount on the day of, the day after, and one week after, the initial unlock event. Our results suggest that a 6-month cliff is favorable to a 1-year or no cliff, and that, somewhat counterintuitively, unlocking a higher proportion of tokens at the cliff is favorable to smaller unlocks (hypothesis C). To explain this, we hypothesize that projects with smaller unlocks have foresight into the likely ‘dumping’ behavior of their investor base, and are looking to minimize sell pressure by unlocking fewer of their tokens.
Finally, we looked at the effect on token price of the amount unlocked at each vesting date following the initial unlock, the gap between unlock events, and the total lockup period. To do this, we looked at each unlock event following the initial unlock and recorded the worst daily normalized return for the day of, the day after, and the week after, an unlock event.
Our results suggest that longer gaps between unlock events (up to 6 months), larger unlocks each period (although this signal is less clear), and shorter overall vesting periods are favorable if the goal is to minimize significant price impacts around unlock events (hypotheses D and E).
As of mid-2022, things seem to be swinging back into the favor of investors given the bear market and the amount of leverage crypto investors have with their fresh dry powder and decreasing competition from generalist funds. We have already seen lower prices, and this is likely to correspond with terms more favorable to investors, such as shorter lockups, at least for now. On the other hand, an increasingly more hostile regulatory environment in the United States may yield minimum cliffs of one year and longer lockups as issuers and investors face uncertain future treatment of all crypto assets.
We would advise any founders reading this to discuss their token vesting schedules with their investors and industry experts with regard to additional tokenomic considerations not covered here. However, our analysis has some preliminary directional indications of the return impact of different vesting schedules, and suggests that linear vesting is favorable to specific date vesting if the goal is to minimize selling pressure at cliff dates and to reduce token volatility over the vesting period. Additionally, we would advise all founders reading this to consult with legal advisors to discuss whether regulatory considerations and protections, such as Telegram considerations, the factors outlined in SEC guidance and the possible benefits to the issuer and investors of complying with the Rule 144 safe harbor framework, may support longer cliffs and longer total lockups to allow for further development and decentralization.
