How long.cards works

A leverage pack is a normal Collector Crypt (CC) pack with a deal attached before it opens. If your card is worth more than the pack price, the pool pays you a bonus on top of the card. If it's worth less, you don't get the card: the pool keeps it and sells it back to CC. Losers' sellbacks pay winners' bonuses, and the pool sits in the middle.

Leverage is optional. It sits next to Pullback's loss coverage, but they are separate: different wallets, different rules.

1. You choose a machine and a level and see every outcome, its chance, the biggest possible bonus and the average result before you commit.
2. You confirm the HIGH RISK warning and sign one USDC payment for the pack price in your wallet. The terms (multiplier, floor, bonus cap) are locked at this moment.
3. Our LEV_OPS wallet buys and opens the CC pack. Because it's our wallet that opens it, the card arrives with us, never directly with you. That's what makes a losing card impossible to keep.
4. We read the card's insured value from CC (GET /api/pack/status) and settle automatically: sell it back, or send you the card (and bonus).
5. The settlement is logged publicly on the Pool page with every transaction link and CC's fairness proof.

Most packs settle within a minute. If CC is slow, the pack waits and retries on its own; your payment is never lost (see Refunds).

The card's value is compared with the pack price P. Values within 5% of the price count as a push.

The cap is , fixed when you confirm the pack. The Open page always shows the exact cap before you pay.

A $100 pack at 1.5x (the multiplier is just for the example):

• $60 card: loss. Full risk gets $0. On a 90% buyback machine, CC pays $54 for the card, so Half risk gets $27.
• $100 card: push. You get the card.
• $300 card: win. You get the card plus (300 − 100) × 0.5 = $100.

And one real settlement from practice mode: a $25 Starter pack at Full risk 2.10x pulled a $28 card, so the player got the card plus (28 − 25) × 1.10 = $3.30.

Half risk: a losing pack still pays you half of what CC pays to buy the card back, so you never lose everything. The multiplier is lower, roughly 1.4–1.9x.

Full risk: a losing pack pays nothing. The multiplier is higher, roughly 2.1–2.9x.

Each machine has its own multipliers. A level shows a lock until it's ready: either more pull data is needed to price it fairly, or the pool needs to grow before it can pay that level's biggest bonuses. Today:

A short is the opposite bet: that the next card anyone pulls on a machine comes out under the pack price. You don't open a pack and you never get a card. Your stake is the pack price.

• Next card under 95% of the price: you win. You get your stake back plus (price − value) × S, where S is the machine's short multiple.
• Within 5% of the price: push. You get your stake back.
• 105% of the price or more: you lose your stake. It goes to the pool.

Example on the $25 machine with S = 2.00: a $20 card is $5 under, so you win $10 and get $35 back. The cheapest card on that machine pays the most. A $30 card, or a $500 one, loses your $25.

Which pull counts: the first pull on that machine that Collector Crypt stamps at least after your payment confirms, by anyone, anywhere on CC. Their pack isn't touched and they never pay you: your stake and your winnings are with the pool. The waiting gap means nobody can short a pull they've already seen.

How S is set: no pack is bought for a short, so Collector Crypt's cut isn't in it. S is solved from the same real pulls as the multipliers, so the pool keeps only its edge:

So your average result on a short is exactly minus the pool edge. S is rounded down to 0.05x. Shorts usually win (about 5 to 8 times in 10, depending on the machine) but win small, and a good card takes the whole stake.

Limits: every short waiting on a machine rides the same next pull, so together they're one bet: their top payouts share the same cap as one pack's bonus (). If no pull comes within , your stake is refunded in full.

Multipliers aren't picked by hand. Every day each one is solved from the machine's real CC pulls over the last , so the pool keeps only a small, fixed edge.

Start from a normal open: buy the pack and sell the card straight back to CC. On average that returns a little less than the pack price (the “normal open” column below). Valued the same way, the pool and the leverage player split exactly what a normal open returns, so:

The pool edge is at launch, dropping to on a machine once its data is strong enough. The multiplier that gives exactly that edge is:

L is the average value of losing pulls (as a share of the price), W is how far winning pulls beat the price on average, and floor is 0 for Full risk and 0.5 for Half risk. With the bonus cap applied it's solved numerically. Multipliers are always rounded down to the nearest 0.05x.

A level only opens when the data is strong enough to be confident the pool really keeps its edge: the 95% lower bound of the pool's result must stay above zero. A level never opens at a worse multiplier to make up for thin data; it waits for more pulls instead.

A card's value is CC's insured value, the reference value CC assigns each graded card and shows on its own site. CC doesn't publish how it sets that value.

When a pack loses, the pool sells the card back through CC's instant buyback, which pays a fixed share of the insured value: 85–93% depending on the machine (the “CC buyback” column above). That money goes straight to the pool, and Half-risk players get half of it.

CC buys cards back for 72 hours after a pull, so losing cards are sold back right away.

The leverage pool is its own wallet (LEV_POOL), separate from Pullback's loss-coverage pool, so a bad run of leverage packs can never touch loss coverage.

• Money in: sellbacks of losing cards, plus 85% of our coin's creator fees. The fees are claimed in $CARDS and swapped to USDC on Jupiter, and every transfer into the pool is listed on the Pool page.
• Money out: win bonuses and Half-risk floors.
• Reservations: while a pack is open, its biggest possible bonus is set aside, so every bonus in progress is always payable. “Free” balance is what's left.
• Unlocks: a level opens only when the free pool can absorb that level's ups and downs (under a chance of running dry) and its bonus cap is at least . Bigger machines unlock as the pool grows.
• Auto-pause: if the free pool drops under , new packs pause until it refills; packs in progress still settle. A machine also pauses if its odds haven't been re-checked in 48 hours.
• Pool HP: the health bar shows the free pool against a target.

Every pull comes from CC's own machines. CC draws them with a verifiable random function (VRF), and each settled pack links to CC's proof (/api/vrf/verify).

The pack's CC order is tied to your purchase before it opens. A pull can't be reassigned to someone else after the result is known.

Each settlement shows its transactions on Solscan, and every entry on the Leaderboard opens its full proof trail:

• payment — your USDC to LEV_OPS
• pack — LEV_OPS paying CC for the pack
• card — the card to your wallet (push or win)
• bonus — the bonus from LEV_POOL (win)
• sellback — CC buying the card back into LEV_POOL (loss)
• floor — your Half-risk share (loss)

• You have 2 minutes to approve the payment in your wallet. If you don't, the pack expires and nothing is charged.
• If CC won't sell from the machine (“machine is low/off”), or the pool can no longer cover the pack's top bonus, you're refunded the full pack price automatically.
• A short with no pull on its machine within is refunded in full.
• If something unexpected happens, the pack goes to manual review. Your payment is safe, and the team either finishes the pack or refunds it. A refund only happens if no pack was bought.

• Opt-in: leverage is off for every wallet until you turn it on, and you can turn it off any time on the History page.
• Every pack asks you to tick “HIGH RISK — you can lose your entire pack price”. The box always starts unticked.
• Your own daily loss limit: lowering it is instant; raising or removing it takes 24 hours.
• Breaks: .
• No pressure: no discounts, no “open another” buttons after a result, no near-miss animations.
• 18+ only. If it stops being fun, stop.
