How PACKD works

PACKD is a pack-opening product on Robinhood Chain (chain ID 4663). Open a drop with USDG and receive a real tokenized stock ERC-20.

$PACKD trading tax (via Flap) funds the prize vault, buybacks, and ops — so the token still earns from volume even though packs are paid in stablecoins.

1. Pay USDG to open — packs are priced in stablecoins.
2. Flap buy/sell tax on $PACKD routes into FeeVault.
3. Vault splits into prizes, buyback & burn, and ops.

Pack proceeds also top up the reserve / jackpot and can buyback-burn $PACKD.

1. Connect a wallet and switch to Robinhood Chain.
2. Hold USDG for packs (and optionally $PACKD to stake for better odds).
3. Choose a drop — Chip Drop, Mega Bag, or Orbit Rip.
4. Approve USDG and open. Your open is anchored to a future block.
5. A moment later it settles: rarity is rolled from that block’s hash and the matching stock token is bought on-chain and sent to your wallet.

Settlement is permissionless — a keeper normally triggers it, but if it ever doesn’t, you can settle your own open and still receive your stock. See Randomness for how the outcome is made fair.

$PACKD launches on Flap as a taxed token (TOKEN_TAXED_V3). Tax routes into our custom vault.

Tax split (FeeVault)

When you open a pack

Flap pays the tax to the FeeVault in native ETH; the vault wraps and swaps it to USDG (prizes) and $PACKD (buyback & burn) with an oracle slippage floor. The owner can pause buybacks (that share goes to ops) or redirect 100% of fees to a single treasury wallet.

Each drop is a curated ticker set with its own odds and payout ranges set on-chain — so the three packs are genuinely different products, not reskins. Only stocks the vault can actually buy on-chain are eligible.

Per-pack rarity odds

Each pack holds one ticker per tier, so the per-stock odds above are exactly what the contract rolls. Rarer tiers pay bigger prize budgets; the exact ranges also differ per pack (Mega Bag has the highest floor, Orbit Rip the biggest legendary ceiling).

PACKD uses a commit-reveal scheme, not a trusted operator roll. When you open, the request is anchored to a future block that doesn’t exist yet.

1. Opening records your entropy + the target block number.
2. After that block is mined, its blockhash is mixed with your entropy and the request ID to pick the outcome.
3. Nobody — not you, not us — can predict a future block hash, so the result can’t be ground or censored. Settlement is permissionless, and a fallback re-anchors the roll if it’s left unsettled too long.

This is fair against the operator today. A hardware VRF (e.g. Chainlink VRF, if available on Robinhood Chain) is the strictly-stronger upgrade and remains on the table for the highest-value drops.

Stake $PACKD for better odds and jackpot multipliers — buy-and-lock demand on top of spend demand.

Hard rule: a payout can never exceed vault reserves. No IOUs — every prize is a real on-chain swap + transfer, and swaps enforce an oracle-based slippage floor when a price feed is configured.

• Every pack is designed with expected payout below its price (~84–87% RTP), so the reserve grows on each open before any fees are added.
• Single payouts are capped as a % of available reserve, and a pull can never exceed what the vault holds.
• Prize budgets shrink automatically if the reserve is low, so the vault can never be drained below zero.
• Flap trading tax continuously refills the reserve on top of pack proceeds.
