Holding Robinhood stock tokens and nervous about next week?
Don't sell them. Hedge them.
Hedge my wallet reads what you hold and sizes a Bear² hedge for it. Nothing in your wallet is moved or locked. Sell the hedge any time.
useparabol.com/mainnet/#hedge
(No guarantee of protection. The hedge costs carry.)
You don't know if it goes up or down.
You just know it's going to move.
That's VOL²: half Bull², half Bear².
Stock +20% → about +6.7%.
Stock −20% → about +10%.
Stock flat → you pay the carry.
Earnings week, anyone?
useparabol.com/mainnet
(Before carry and fees.)
Most apps show you what you could win.
We show you what you could lose. Before you click buy.
$5 of NVDA Bull². NVDA +20% in 30 days → $7.00.
Flat for 30 days → −$0.14.
NVDA −20% → −$1.89.
That's the Squared Receipt.
useparabol.com/mainnet/#recei…
Market down? You can still win.
NVDA −5%. AMD −15%.
Back NVDA over AMD → +24.9%.
A Duel doesn't care where the market goes. Only which stock does better.
4 match-ups live: NVDA/AMD · MSFT/GOOGL · TSLA/PLTR · QQQ/SPY

(Before carry, fees and the payout cap.)
NVIDIA this month: −6.9%.
Bull² index: −13.3%.
Bear² index: +15.4%.
Same stock. Same month. You pick the side.

Why Parabol² exists.
Robinhood Chain put real stocks on chain. Most of what got built on top is a copy of something you can already do at a normal broker.
We wanted one thing you can't: hold the square of a stock's move.
NVDA +10% → Bull² about +21%.
NVDA −10% → Bear² about +23%, with a built-in cap.
(Before the daily carry.)
Fully paid. No margin, no liquidation, no expiry.
That doesn't make it safe. Squared moves cut both ways, there is a daily carry, and you can lose what you put in. But it's new, it's simple, and it only works on chain.
That's why we build it.

Hey, thank you. Honestly, this one made our day.
Messages like yours mean more than you'd think. Building something new is mostly quiet work: long days, small numbers, and a lot of people scrolling past. So when someone says "I've been watching since launch, keep going", it lands.
You're right that everyone starts from the beginning. We did too. Our vaults are still small and our limits are small on purpose, because we'd rather grow slowly and safely in public than fast and sloppy. Every number we show is read straight from the contracts, so anyone can check it.
And you nailed the hardest part: getting people to understand it. Squared exposure sounds complicated, and people are afraid of what they don't understand.
That's fair. So that's exactly where a lot of our work is going:
· a free practice mode, so you can try it without real money
· the Squared Receipt, which shows in plain numbers what a move would do to your position
· simpler explanations, like "Bull² is the bouncy version of a stock"
We're not going anywhere. We just shipped Phase 2, and there's more coming. We'll keep adding, keep fixing and keep explaining until it clicks for a lot more people.
If anything ever confuses you on the site, or you have an idea that would make it easier to understand, please tell us. Feedback from people who've followed us from day one is gold.
Thanks again for the support. It genuinely helps. 🙏
Parabol² team
They thought we were done.
We weren't. Phase 2 of Parabol² is live on Robinhood Chain, and you don't have to take our word for it. Every claim below links to the chain.
━━━━━━━━━━━━━━━
WHAT PHASE 2 IS
━━━━━━━━━━━━━━━
In phase 1 everyone had the same small limit. In phase 2, your $PARABOL stake sets your own trade limit, and part of the trading fees you pay comes back to you every week, in USDG.
Max trade size per tier:
· No stake: $10
· Bronze (250K $PARABOL): $50, 10% fee rebate
· Silver (1M): $100, 20% fee rebate
· Gold (5M): $250, 30% fee rebate
· Platinum (10M): $250, 40% fee rebate
The trading engines read your tier straight from the staking contract on every buy. Selling is never limited by your tier.
━━━━━━━━━━━━━━━
HOW TO USE IT
━━━━━━━━━━━━━━━
1. Go to useparabol.com and tap "Phase 2 is live"
2. Type how much you'd stake and see your tier
3. Hit Stake, connect your wallet, approve, then stake
4. Trade: your limit and your rebate follow your tier
━━━━━━━━━━━━━━━
PROOF: IT'S ON CHAIN
━━━━━━━━━━━━━━━
Phase 2 is switched on in the staking contract itself.
currentPhase() returns 2. 3.3M $PARABOL is staked right now.
robinhoodchain.blockscout.com/address/0xC4c6…
Both trading engines read their tier from the TierAdapter:
robinhoodchain.blockscout.com/address/0x47Ca…
Weekly fee rebates go out from the FeeRebateDistributor, owned by the Safe:
robinhoodchain.blockscout.com/address/0x47BC…

PROOF: THE MONEY IS THERE
━━━━━━━━━━━━━━━
Every vault is a public contract. Open it, check the USDG balance yourself.
Bull² vault: holds 29.04 USDG (cash plus its stock hedge), owes 4.75 USDG to open positions, 24.30 USDG net
robinhoodchain.blockscout.com/address/0x8d7E…
Bear² vault: 24.00 USDG
robinhoodchain.blockscout.com/address/0x716F…
Duels vault: 25.00 USDG
robinhoodchain.blockscout.com/address/0x57fF…
Bull² and Bear² vaults together: 53.04 USDG held, 4.75 USDG owed right now. That is 11x coverage.

PROOF: NO ONE CAN DO IT ALONE
━━━━━━━━━━━━━━━
Every upgrade and every setting change goes through a 2-of-3 Safe. No single key can touch the engines or the vaults.
robinhoodchain.blockscout.com/address/0x9a6D…
The new code the Safe upgraded to (check the implementation on each proxy):
· Bull² engine: 0x9254a77403119c480b7af63cbdb0428abfb560ce
· Bear² engine: 0xeb5b6d5f6ffbf5aeeaa54316a95768f394445c1a
· Bull² vault: 0xf769ff7a9bdaf47b18f189cd4faf737601a0a9d9
· Bear² vault: 0x185cfe6ab2b5860b3aab6185612cd38d8b7f5265
━━━━━━━━━━━━━━━
SECURITY FIXES SHIPPED
━━━━━━━━━━━━━━━
The same upgrade fixed seven findings from our internal security review: PRB-M2, M4, M5, M6 and M7, plus L1 and L2. M1 was fixed on 17 Oct.
The full report is public, open findings included. We'd rather show you what's left than pretend nothing is:

Internal review, not an independent audit. Early access with small limits. Leveraged products can lose value fast, and you can lose what you put in. Not investment advice.
Parabol², explained like you're 10 🧸
Imagine a stock, like NVIDIA.
When it goes up 10%, a normal share goes up 10%.
Bull² is a "bouncier" version.
NVIDIA up 10% → Bull² up about 21%.
NVIDIA down 10% → Bull² down about 19%.
Small moves get roughly doubled. That's the "squared".
Bear² is the opposite.
It goes up when the stock goes down.
NVIDIA down 10% → Bear² up about 23%.
It has a built-in cap, so it can't go up forever.
The rules are simple:
· You pay in full. No borrowing.
· Nobody can force-close you. No liquidation.
· No end date. Sell when you want.
· The most you can lose is what you put in.
The catch, honestly:
· Bouncy works both ways. Losses get bigger too.
· There's a small daily fee (carry) for holding.
· It's early, so limits are small: $10 per trade to start.
Want to try it without real money first?
There's a free practice mode on useparabol.com
Not investment advice. Start small. 💙
