Leverage your next Collector Crypt pull.

Beat the pack price and the pool pays you a bonus on top of your card. Miss it, and the pool keeps the card. Optional, honest odds, and you can lose your entire pack price.

Real Collector Crypt machines. Each one gets its own multipliers, worked out from its recent pulls.

How it works

Four steps, fully on-chain

  1. 01

    Pay the pack price

    One USDC payment from your wallet. Terms are locked when you confirm.

  2. 02

    The pool opens it

    Our pool wallet buys and opens the Collector Crypt pack, so it holds the card.

  3. 03

    Value decides

    Below the price is a loss, within 5% a push, above it a win, by CC’s insured value.

  4. 04

    Settled & logged

    Card and bonus to you, or the card is sold back. Every transaction is public.

1.5x is only for the example. Real multipliers are set per machine from Collector Crypt's pull data so the pool keeps about a 3–5% edge.

Levels

Pick your risk

Half risk

about 1.4–1.9x

Lose, and you still get half of what Collector Crypt pays to buy the card back.

Full risk

about 2.1–2.9x

Lose, and you get nothing. The multiplier is higher.

Short

about 0.5–2x per $1 under

Bet the next card anyone pulls is under the pack price. Wins often but small; a good card takes your stake.

Every level leaves the pool the same small edge (about 3–5%): your average is a normal open's minus that edge, or just minus the edge on a short. See the math
The pool

The pool sits in the middle

A separate wallet, so leverage never touches Pullback's loss coverage. Bigger machines unlock as it grows.

Losing packs

The card is sold back to Collector Crypt; the USDC goes to the pool.
