# Staking Protocol

SPA holders can stake SPA tokens and receive veSPA tokens which are non-transferable. veSPA balance is proportional to the lockup period, meaning if user locks up for higher duration they receive proportionally more veSPA tokens. veSPA balance determines the share of staking reward and voting power

1. **Staking rewards**: Rewards will be distributed proportionally to the user's veSPA balance. Users who lock SPA for longer periods are eligible for proportionally more rewards (accrued on a weekly base) than users who locked the same amount of SPA for shorter periods. Rewards are accumulated through:

   * As per [SIP-66](https://snapshot.box/#/s:speraxdao.eth/proposal/0x401841b87ef3b503e8732eaace2b867faab15b91383e94bad9c90ec61e2540cd), the emission of xSPA for veSPA holders has been increased to 420,000 xSPA tokens per week from the treasury to account for the decrement in APR due to cutting the allocation from bought-back SPA.
   * **Fee Rewards** - 100% of the Fee income from USDs mints and redemptions.

   The yield and fee income are originally generated in USDs. It is then swapped for SPA tokens before distribution. This makes the reward claiming process simple for stakers and maintains a constant buying pressure on the SPA token.
2. **Voting power**: once governance protocol is launched, voting power will depend on users' veSPA balance. Users who are committed to longer lockups will own more votes, whatever they are voting for.

veSPA balance at the moment of staking will not stay the same all the time - it will decay/reduce linearly. User's rewards per week and voting power will also decrease over time, together with the veSPA balance. Stakers can increase their veSPA balance and thereby their staking rewards and voting power by either extending the locking period or locking more SPA or re-staking SPA rewards.

At the end of the lockup period, veSPA balance will reduce depending on the pre-selected withdrawal option:

1. For Auto-cooldown option - to zero.
2. For the "Staying Staked" option (manual cooldown) - to \[0.01917\*staked SPA tokens]. Please note that for new stakers the "Staying Staked option" is not available.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sperax.io/staking-protocol.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
