# Airdrop — Season 2
## TL;DR — How season 2 works
* **Points system:** Most of it stays the same — swaps, liquidity, referrals, and boosters.
* **New points farming option “Pool manager”:** Create and manage a pool and earn points based on the pool’s fees.
* **Lottery system and cap:** We’re introducing a lottery system (capped at 2,500 users) where your chances of being selected scale with the number of points you’ve earned.
* **Rewards scaling:** Between the minimum and maximum reward, there will be a maximum 50x difference.
* **No overweight:** Whales can’t claim 90% of the pie anymore.
## Fairer. Smarter. More Inclusive.
After the successful close of season 1, we’re excited to introduce a refined and fairer model for season 2 — one that maintains strong incentives for power users while ensuring smaller wallets get a real chance at meaningful rewards. Our new “Pool manager” function gives users the chance to earn points based on their effort and activity rather than only their funds.
## What’s staying the same?
* **Execute swaps:** 5 (stable pools) & 10 (weighted pools) points per USD value equivalent swapped.
* **Deposit liquidity:** 50 (stable pools) & 100 (weighted pools) points per USD value equivalent per day.
* **Referral links:** Use the referral system to earn extra points. Share your referral link and get 50% of the points your referees earn. These extra points are not deducted from your referees’ points, instead, your referees earn an additional bonus of 10% when using your referral link.
* **Boosted pools and wallets:** When interacting with boosted pools or wallets, a 2x points booster will be applied.
Nothing changes in how you earn points. Your activity = your points.
## **What’s changing in season 2?**
* We’re going to discontinue our booster NFT due to its technical limitations.
* Create and manage pools to earn points based on the pool’s fees.
* In season 1, rewards were distributed strictly proportional to the number of points. While this rewarded capital-heavy users, it disadvantaged smaller, but active users. Season 2 introduces a fairer reward distribution.
## 1. Earn points as a pool manager
**Become a pool manager:** Create a pool, add some liquidity, attract more liquidity, and let the pool’s TVL and volume grow. You’re in charge of the pool’s settings to keep it well-performing — the more fees the pool earns, the more points you will get: 10,000 points per USD value equivalent of earned fees.\
**Pro tip:** Share your pool with your friends or community to let it grow by using your referral link.
## 2. A fairer airdrop distribution mechanism
### Capped recipients
Only a maximum of 2,500 wallets will receive an airdrop in season 2. This helps us maintain a meaningful reward amount for each recipient and ensures the distribution remains focused and impactful.
### Weighted lottery
We’re introducing a lottery system where your chances of being selected scale with the number of points you’ve earned. But here’s the twist:
### Non-linear weighting — How does the draw actually work?
**Here’s the process:**
1. Each user earns points pᵢ
2. We calculate the weights using: wᵢ = ln(1 + pᵢ) to proportionally decrease the weight effect of large point values.
3. Normalize the weights into probabilities Pᵢ: Pᵢ = wᵢ / ∑ wᵢ
4. A total of 2,500 winners are chosen through the following procedure. Assume a finite population of users **a** = \[a1, a2, . . . , aN] with the size N and k ⫹ N is the winner’s sample size. We select k elements from **a** by using the random choice principle with the probability weights vector **p** = \[p1, p2, . . . , pN], where pᵢ ⫺ 0 and ∑ from i=1 to N of pᵢ equals 1. The algorithm proceeds as follows:
* For each i ∈ {1, . . . , N}, we draw uᵢ ∼ 𝒰 (0, 1).
* We compute the priority key as Kᵢ= uᵢ^1/pi.
* Then we select the k indices with the largest Ki values.
**So yes:**
* Users with more activity (points) have a better chance of winning
* But even smaller wallets have non-zero odds
### Fair reward scaling (max 50x spread)
Once the 2,500 winners are drawn, rewards are **not all equal** — but they’re capped. The most active wallet can receive no more than 50x the reward of the lowest-scoring winner.
**Here’s how we do it:**
1. Each winner’s score (sᵢ) is calculated using a logarithmic function to compress differences: sᵢ = ln(1 + pᵢ)
2. Then, scores are linearly scaled across all winners, ensuring that the total airdrop amount stays fixed and the maximum reward is capped at 50x the smallest: rewardᵢ = Rₘᵢₙ + (sᵢ — Sₘᵢₙ) / (sₘₐₓ — Sₘᵢₙ) \* (Rₘₐₓ — Rₘᵢₙ)
Where:
* sᵢ is the score of wallet i
* Sₘᵢₙ, sₘₐₓ are the minimum and maximum scores among the winners
* Rₘᵢₙ is dynamically calculated to ensure the total payout sums to exactly the season 2 value
* Rₘₐₓ = 50 \* Rₘᵢₙ
## Why those changes matter
* Smaller users now have a meaningful chance of receiving tokens.
* Whales still benefit from their activity, but can no longer dominate the airdrop pool.
* Fairness meets incentives — and rewards remain competitive for everyone.
