Lottery Tickets and Pool Weights Explained

Lottery tickets

Lottery tickets are available from tiers 1–4. They determine the winning chances an eligible user has. The higher the tier, the more lottery tickets you have and the higher your chance of winning a whitelist spot when participating in our IDO projects.

Pool weights

Pool weights determine a user’s allocation size. The higher the multiplier, the bigger the allocation. We’ve designed it this way to incentivize upgrading your tier, be it in FS tokens or FS key. Stay tuned for Smart Subscription .

A Case Study

Winning odds for a lottery ticket using 20 participants.

Based on the Table above, there are a total of 48 Tickets. Participants are picked randomly through a smart contract RNG.

Tier 1 individual chance of winning: 1/48 = 2%
Tier 2 individual chance of winning: 2/48 = 4%
Tier 3 individual chance of winning: 4/48 = 8%
Tier 4 individual chance of winning: 8/48 =16%

Full Case Study

Let’s consider a Public Sale of 1000 $XYZ tokens is shared between 300 winners (200 from tier 5,6,7 and 100 from tier 1,2,3,4 lottery).

Tier winners allocation formula:

1000 (Total $XYZ tokens) / 2400 (Total Weight)) x (Tier Pool Weight) = Individual Allocation.
