# Staking & Fee Sharing

> Stake $PETRA to earn protocol revenue and unlock lower trading fees.

Staking is the core mechanic of \$PETRA. You lock tokens in the Staking Vault, earn a cut of Perpetra's trading fees in USDC, and unlock reduced fee tiers for your own trades.

## Staking Vault

The Staking Vault is a smart contract on Robinhood Chain. You deposit \$PETRA; in return, you earn a pro-rata share of the protocol's fee revenue.

**How it works:**

1. Deposit \$PETRA into the Staking Vault
2. Protocol trading fees accumulate in the vault (in USDC)
3. Rewards are distributed proportionally to your stake
4. Claim USDC rewards anytime

Your share of rewards depends on two things: how much you stake relative to the total vault, and how much volume the protocol does.

<Tip>
  Rewards are paid in USDC—not in more tokens. This is real yield from real trading activity, not dilutive emissions.
</Tip>

### Revenue Split

A percentage of all taker fees collected by Perpetra flows to the Staking Vault. The exact split is subject to governance, but the initial parameters are:

| Destination           | Share             |
| --------------------- | ----------------- |
| **Staking Vault**     | 40% of taker fees |
| **Insurance Fund**    | 20% of taker fees |
| **Protocol Treasury** | 40% of taker fees |

As the protocol matures and the Insurance Fund reaches target capitalization, governance can vote to redirect a larger share to stakers.

### Unstaking

Unstaking has a **7-day cooldown**. Once initiated, your tokens unlock after the cooldown period. During cooldown, you stop earning rewards on the unstaking amount. No slashing—you always get your full principal back.

<Warning>
  During the cooldown period, your unstaking tokens do not earn rewards. Plan accordingly.
</Warning>

## Fee Tiers

Staking \$PETRA unlocks better trading fees. The more you stake, the lower your taker rate.

| Tier         | Staked \$PETRA | Taker Fee | Maker Fee |
| ------------ | -------------- | --------- | --------- |
| **Base**     | 0              | 0.060%    | 0.000%    |
| **Bronze**   | 1,000+         | 0.050%    | 0.000%    |
| **Silver**   | 10,000+        | 0.040%    | 0.000%    |
| **Gold**     | 50,000+        | 0.035%    | Rebate    |
| **Platinum** | 200,000+       | 0.030%    | Rebate    |

<Info>
  Fee tiers stack with volume-based tiers. If you qualify for a better rate through volume alone, you keep the better rate. Staking can only improve your fees, never worsen them.
</Info>

These tiers apply automatically. Stake the threshold amount and your next trade uses the new rate—no application, no waiting.

## Insurance Fund Staking

Beyond the standard vault, you can optionally stake \$PETRA into the **Insurance Fund Pool**. This pool backstops the protocol's liquidation engine. In exchange for taking on tail risk, you earn a share of liquidation fees.

| Market        | Liquidation Fee to Pool      |
| ------------- | ---------------------------- |
| BTC, ETH, SOL | 0.30% of liquidated notional |
| Others        | 0.60% of liquidated notional |

Insurance Fund staking carries more risk. In extreme market conditions (cascading liquidations, ADL events), the pool absorbs losses before the main Insurance Fund. Only stake here if you understand the risk profile.

<Warning>
  Insurance Fund staking is higher risk, higher reward. Your principal can be partially used to cover protocol shortfalls in extreme scenarios. This is not a risk-free yield.
</Warning>

## Governance

\$PETRA holders who stake in the vault can vote on protocol decisions:

* **Market listings** — Propose and vote on new perpetual markets, especially RWA pairs
* **Fee parameters** — Adjust the revenue split between stakers, insurance, and treasury
* **Protocol upgrades** — Approve changes to vault mechanics, cooldown periods, or tier thresholds

Voting power is proportional to your staked balance. Tokens in cooldown do not count toward voting power.

<Info>
  Governance is on-chain and transparent. Proposals require a minimum quorum to pass, and all votes are publicly verifiable on Robinhood Chain.

## Quick Reference

<AccordionGroup>
  <Accordion title="How often are rewards distributed?">
    Rewards accrue continuously as trades execute. You can claim accumulated USDC at any time—there's no fixed distribution schedule.
  </Accordion>

  <Accordion title="Is there a minimum stake?">
    No minimum for the Staking Vault. Fee tier benefits kick in at 1,000 \$PETRA (Bronze tier).
  </Accordion>

  <Accordion title="Can I stake and trade at the same time?">
    Yes. Staking and trading use separate balances. Your USDC collateral for trading is independent from your staked \$PETRA.
  </Accordion>

  <Accordion title="What happens if I partially unstake?">
    Only the unstaked portion enters cooldown. The rest keeps earning rewards and maintaining your fee tier (as long as you stay above the threshold).
