# SDT Spiral Locker

In exchange for locking SDT  in a Spiral Locker, users receive a liquid version of veSDT — Spiral Stake DAO (**sprSDT) token** — a token retaining boosting power that is transferable and tradable.

## **sprSDT Staking**

* By staking sprSDT, users are able to acquire boosting power that can be utilized, sold, or delegated. 
* This comes with additional native SPR incentives.

## sprSDT Boost Delegation

With the SDT Spiral Locker, users can manage their boost delegation via the locker page, selecting their desired time periods and delegation addresses. The system allows a flexible approach to boost delegation, including re-delegation, to maintain optimal boost power over time. This feature is set to expand, with support for Concentrator and Paladin boost markets to be added in the future. 

### **Delegating boosts to any address**

sprSDT holders can delegate their boosts to any address, personalizing their utilization strategy on Stake DAO.

### **Delegating boosts to Concentrator** *(Coming Soon)*

This feature will allow users to delegate boosts to the Concentrator for additional rewards.

### **Delegating boosts to Paladin** *(Coming Soon)* 

With Paladin launching a new product to augment its boost marketplace capabilities, users will be able to delegate boosts to Paladin's marketplace directly through the Spiral website.

## sprSDT Voting Power

Initially, the SDT voting power will not be distributed, as integrating this feature is technically challenging and not currently a priority.

## **sprSDT Liquidity**&#x20;

Will be added during the week after launch. Users will be able to participate as liquidity providers in the sprSDT/SDT pool to earn additional rewards.

## Fees

* **Minting Fee:** No fee will be charged for minting.
* **Staking Fee:** Initially, there will be no fees for staking. However, a 10% fee will be introduced in the upcoming months.
