### Retroactive Airdrop

The OP retroactive airdrop is distributed to the users who are early users of the Earn Vaults v1, as per this [Governance Proposal](https://gov.optimism.io/t/gf-phase-0-proposal-polynomial-protocol/1625).

**Snapshot date**: Friday, 13 May 2022 (1652429638)

**Amount** : 180,000 $OP

#### Criteria

* Users should have deposited at least $69
* Participated in min. one active round. 

**Formula**

$$
f(x) =  \sum W(t)\cdot t - \sum \cdot D(t)\*t  + ST\cdot RF
$$

W(t) withdraws the amount at time t,

D(t) deposit amount at time t. 

ST = snapshot time, 

RF = remaining funds. 

All times are in unix timestamp In the end; the whole score is divided by 604800 (number of seconds in week/round)

{% endhint %}

**Amount** : 450,000 $OP

**Criteria** : Future users of Polynomial Products

Future vault users of the polynomial earn vaults will earn liquidity mining rewards.

$$
f(x) = \alpha \* (OP \* C\_x )/\sum(C\_i)
$$

OP is Total OP allocation  

C is vault capacity 

Alpha is vaults multiplier (newer vaults \~1.5-2x).
