# Perpetual Airdrop Vault

#### **Who This Vault Is For**

This vault is designed for users and LPs who want to maximize their exposure to airdrops and take the full upside of incentive programs.By that, depositors willingly forgo their share of native yield in exchange for greater leverage on airdrop rewards sourced from the protocol’s aggregated capital base.&#x20;

#### **How the Mechanism Works**

Once assets are deposited into the Spreads Mother Vault, users may **lock their position for any duration between 1 and 12 weeks**. A full 12-week lock mints **1 sprFARM** token per unit deposited, while shorter lock periods receive exponentially less exposure.

The locking framework follows a **short-cycle veCRV-style model** where the weight decays linearly as the lock approaches its expiry, and users may extend their lock at any time.&#x20;

#### **Weighting Model**

The exposure boost is determined by a predefined curve anchored at your chosen values:

* **1 week → 0.02× exposure**
* **4 weeks → 0.35× exposure**
* **12 weeks → 1.00× exposure**

To generalize this behavior, we use a piecewise linear function:

$$
weight = 0.02 + 0.98 × (durationWeeks - 1) / 11
$$

This structure strongly incentivizes longer commitments and exponential upside for users who prove long term commitment

#### **Strategy Coverage**

The vault farms two categories of opportunities:

1. **Points-based protocols**
   * A daily snapshot records each user’s sprFARM balance and weight.
   * Weekly points received from partners are synthetically distributed based on these weights.
   * Users can track their evolving points share in real time through the interface.
2. **Point-less protocols**
   * Details on non-points incentives, performance metrics, and distribution logic are covered in [Spreads Points](/documentation/perpetual-airdrop-token/spreads-points.md)

When the underlying projects settle their airdrops, **users claim directly from the Spreads Airdrop Vault**, ensuring a unified and auditable distribution pathway.

#### **How to Deposit**

1. Visit **mint.spreads.fi**
2. Deposit **USDC on Ethereum**
3. Receive **spr** tokens
4. Navigate to the **Earn → Yield Vault** section
5. Lock your spr tokens between 1 week and 12 weeks and farm airdrops passively

The protocol charges 20% on all points generated by the strategy

#### **Key Risks**

* **Airdrop underperformance:** Projects may deliver fewer rewards than expected.
* **Program pivots:** Some protocols may abandon or reduce airdrop campaigns.
* **Extended settlement timelines:** Airdrops often take weeks or months to finalize.
