Introduction
JackPackz is a provably-fair booster-pack platform on Robinhood Chain. Pick a pack, rip it, and a fair on-chain roll drops a real tokenized asset — a stock or a Robinhood-chain meme — straight into your wallet. Non-custodial by design: every asset lives in your wallet, never ours.
Think trading-card booster packs, but every card you pull is a real ERC-20 token. Blue-chip stocks give you the floor; memes give you the moonshot. Rarity, upside and the jackpot are decided by verifiable randomness — no house-controlled outcomes.
One rip, a real asset
Every opening settles a genuine tokenized stock or meme to your wallet.
Non-custodial
Assets go straight to your wallet. JackPackz can't move, freeze or reclaim them.
Provably fair
Published odds + on-chain VRF. Anyone can verify every roll.
Routed on-chain
Best-price swaps across Robinhood Chain liquidity in one atomic transaction.
What ships today
The landing experience, wallet connection on Robinhood Chain, the full pack & collection catalog, and provably-fair reveal previews. On-chain minting via Uniswap v4 and the jackpot vault roll out as liquidity deepens — tracked in Contracts.
Who it's for
Degens who love ripping packs, collectors chasing the set, and anyone who wants exposure to tokenized stocks and Robinhood-chain memes without juggling ten swaps and ten tabs.
How this documentation is organised
Start with Quickstart to rip your first pack. Core concepts explains packs, cards, rarity, $JACKZ and the jackpot. Using JackPackz covers the day-to-day. On-chain documents the contracts and security model.
Quickstart
From zero to your first pull in under a minute.
- Connect a wallet. Click Connect Wallet — Robinhood Wallet, MetaMask or Coinbase. The app adds Robinhood Chain automatically.
- Pick a pack. Browse the catalog — AI, Magnificent 7, Meme Moonshot and more. Each shows its published odds.
- Rip it. Pay in USDG. A provably-fair VRF roll selects your asset and swaps for it on-chain.
- Own it. A real tokenized asset settles to your wallet. Sell it anytime on any Robinhood Chain DEX.
Every rip also grows the shared jackpot vault — one lucky opening takes the pot.
Connect a wallet
JackPackz uses standard EVM wallet connection (EIP-6963 multi-wallet discovery). Supported out of the box:
- Robinhood Wallet — native to the chain.
- MetaMask — the most common EVM wallet.
- Coinbase Wallet — mobile & extension.
On connect, the app checks your network and, if needed, prompts you to add or switch to Robinhood Chain (chainId 4663) via wallet_addEthereumChain. No seed phrases, no custody — you approve each action in your own wallet.
JackPackz will never ask for your seed phrase or private key. Only ever sign transactions you understand.
What is a pack
A pack is a sealed, themed booster you buy — for example the AI Pack or Magnificent 7. Each pack draws from a curated pool of assets. When you rip it, a provably-fair roll reveals which card(s) you get, and the corresponding real token settles to your wallet.
Packs collapse what used to be ten tabs, ten swaps and ten fees into a single signed transaction: pick a pack → we route your USDG through Robinhood Chain's on-chain aggregator → the revealed asset lands in your wallet as a real ERC-20 token.
Packs vs cards
Two different objects — this trips people up, so it's worth being precise:
Pack
The sealed foil booster you buy. Themed (AI, Mag7, Meme…). Contains cards.
Card
What you pull from a pack. Each card = one real tokenized asset, with a rarity.
You buy packs; you collect cards. Complete a set of cards to earn collection rewards.
Rarity & odds
Every card has a rarity, and every pack publishes its weighted odds. The rarest assets are the hardest to pull — and the ones that flex hardest on the timeline.
Holding & staking $JACKZ tilts these odds in your favour by tier.
The $JACKZ token
$JACKZ is the engine of the platform, not just a ticker. It powers the loop and shares the upside with the community.
- Luck boost — stake to raise your rare-pull odds by tier.
- Vault rake — stakers share pack fees and jackpot rake.
- Pay-in discount — open packs with $JACKZ for a fee discount.
- Exclusive drops — holder-gated limited seasonal boosters.
Contract address: soon — published here on launch.
The jackpot vault
Every pack you rip feeds a shared, non-custodial jackpot vault. It's locked in the smart contract — the team can't withdraw it. Someone has to win it, or it stays locked forever.
- Every opening contributes a small amount to the vault.
- 1 in 25,000 rips wins 90% of the pot.
- The remaining rake is shared with $JACKZ stakers.
The vault balance and every payout are verifiable on-chain.
Opening a pack
- USDG in. Your payment enters the pack contract.
- Verifiable randomness. A provably-fair VRF draw selects your asset.
- Uniswap v4 swap. USDG swaps for the asset on-chain, best-price routed.
- Real ERC-20 minted. A tokenized stock or meme, Chainlink-priced.
- Settles to your wallet. The card is yours — self-custody, always.
The whole flow is one atomic transaction. If any step fails, nothing settles and you keep your USDG.

Provably-fair reveals
Outcomes are decided by on-chain verifiable randomness (VRF), not a server the team controls. Each pack's odds are published up-front, and every roll produces an on-chain proof you can inspect.
Because the randomness is committed on-chain, neither the team nor a player can predict or alter the result. This is the trust core of JackPackz: the gamble is on which asset and what rarity — never on whether you receive a real asset at all.
Collections & sets
Cards belong to collections. Complete a portfolio to earn a badge, a bonus asset, and a free pack. Examples:
- AI Collection — NVDA · AMD · INTC · MU → +$5 bonus, 1 free pack.
- Magnificent Seven — the seven titans → +$10 bonus, 2 free packs.
- Meme Legends — WSB · VLAD · ROCKET · CASHCAT · WOJAK → +$6 bonus.
Progress is tracked per wallet and settles rewards on completion.
Selling & redeeming
Because every card is a real ERC-20 token in your own wallet, you're never locked in. Sell any asset anytime — on JackPackz or on any Robinhood Chain DEX. There is no wrapper token, no vault, no manager holding your assets.
What you see in your wallet is what you own. JackPackz can't reclaim it.
Staking & luck boost
Stake $JACKZ to earn a share of platform fees and jackpot rake, and to unlock luck-boost tiers that raise your rare-pull odds. Higher tiers = better odds and bigger rake share. Staking, tiers and reward math are published at token launch.
Pack themes
Six curated boosters at launch — each a themed foil pack drawing from its own pool of assets.
AI Pack
Magnificent 7
Meme Moonshot
Index Pack
Dividend Kings
Future Tech
Coming soon
Some packs go live as their underlying assets are tokenized / bridged onto Robinhood Chain. For example, Dividend Kings unlocks fully once KO, PG, JNJ and PEP hit the chain. New seasonal and limited packs (Earnings Season, Meme-stock revival, AI-bubble) drop over time — holder-gated for $JACKZ stakers.
Robinhood Chain
JackPackz runs on Robinhood Chain, an Ethereum Layer-2 purpose-built for real-world assets and tokenized stocks. Key parameters:

Uniswap v4 routing
When you rip a pack, USDG is swapped for the revealed asset through Uniswap v4 pools on Robinhood Chain. Prices are read from live pools and Chainlink oracles. Routing finds the best price across available liquidity and executes atomically in the same transaction as the reveal — no inventory, no IOUs.
Contracts
Addresses are published here as they deploy. Until then they read soon.
| Contract | Address |
|---|---|
| $JACKZ token | soon |
| Pack contract | soon |
| Jackpot vault | soon |
| USDG | soon |
Security
- Self-custody — assets settle directly to your wallet; the app never holds keys.
- Non-custodial jackpot — the vault is locked in-contract; the team cannot withdraw it.
- Provably fair — outcomes use on-chain VRF with published odds.
- No secrets in the client — all sensitive config is server/env-side; nothing private is hardcoded.
Always verify the contract address before interacting, and only sign transactions you understand.
FAQ
Do I always get something real?
Yes. Every rip settles a real tokenized asset to your wallet. The randomness decides which asset and what rarity — never whether you receive value at all.
Can the team rug the jackpot?
No. The vault is non-custodial and locked in the smart contract. It can only pay out to winners.
Can I sell what I pull?
Anytime — on JackPackz or any Robinhood Chain DEX. Your cards are standard ERC-20 tokens.
Is $JACKZ live?
Not yet — contract shows soon until launch. Utility (staking, luck boost, rake) ships with the token.
Risk & disclaimers
Opening packs involves chance and financial risk, including loss of principal. Digital assets are volatile and memecoins can go to zero. Nothing in this documentation is financial advice. Provably-fair gaming mechanics may be restricted in some jurisdictions — you are responsible for compliance with your local laws.
