Staking Vault
The Staking Vault is a smart contract on MegaETH. You deposit $PETRA; in return, you earn a pro-rata share of the protocol’s fee revenue. How it works:- Deposit $PETRA into the Staking Vault
- Protocol trading fees accumulate in the vault (in USDC)
- Rewards are distributed proportionally to your stake
- Claim USDC rewards anytime
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 |
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.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 |
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.
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 |
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
Governance is on-chain and transparent. Proposals require a minimum quorum to pass, and all votes are publicly verifiable on MegaETH.
Quick Reference
How often are rewards distributed?
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.
Is there a minimum stake?
Is there a minimum stake?
No minimum for the Staking Vault. Fee tier benefits kick in at 1,000 $PETRA (Bronze tier).
Can I stake and trade at the same time?
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.
What happens if I partially unstake?
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).
