Gacha
Gacha opens Collector Crypt machines from your own wallet. Each pull is a vaulted graded card delivered as an NFT. Omni shows the machine's math before you pay and the keep-or-sell call after you pull.
- Omni fee
- $0.00
- Paid in
- USDC on Solana
- Per open
- 1, 3, 5, or 10
- Sell-back window
- 72 hours
Open it at /packs. You pay Collector Crypt directly from your wallet. Omni never holds the funds and adds no fee. Solana charges a small network fee in SOL.
Opening gacha
- Pick a machineEach machine has a gacha price, published odds for four tiers (Common, Uncommon, Rare, Epic), and a buyback rate.
- Choose a quantityOpen 1, 3, 5, or 10 at once. The total is shown in USDC before you start.
- Approve in your walletCollector Crypt builds the purchase for your wallet. You sign it, and Omni relays exactly that transaction, nothing else. If the wallet cannot cover the full amount, the open is rejected and nothing is signed.
- The drawCollector Crypt draws each card with on-chain randomness (VRF). The card’s NFT goes to your wallet. A pack that stays unopened for more than 2 hours is refunded in USDC by Collector Crypt.
- Keep or sell backFor each pull, Omni shows the instant buyback next to what the card is likely to fetch on resale, and marks the better exit.
Reading a machine
- Gacha
- What one open costs.
- CC EV
- Collector Crypt's average insured value per gacha, weighted by its published odds. Insured value is not cash; you only realize it by selling back or reselling.
- Market EV
- What a gacha is worth if you take the better exit on every card: the higher of sell-back and resale, where resale is the lower of last sold and Alt.xyz Value, minus 2% for selling fees. Shown as ≥ while under 60% of the prize pool has a market price.
- Sell-back EV
- What a gacha is worth if you sell every pull straight back. CC EV times the buyback rate.
- Beats gacha
- The chance a single pull is worth more than the gacha price, taking the better exit on that card.
- Buyback
- Collector Crypt's instant buyback rate, paid on the card's insured value.
Percentages next to each figure compare it with the gacha price. Green means the figure is above the price.
Tier gaps
Each tier shows how many pulls have passed since it last hit, against its average gap. Once a tier has at least 20 recorded hits it is labelled Cold (under half its average gap), Warming (under its average), or Hot (at or past it).
Selling back
Collector Crypt buys a pull back at the machine’s buyback rate for 72 hours after it is drawn. Choose Sell back on the pull, approve the transaction, and the USDC is paid to your wallet. After 72 hours the card is yours to keep, list, or redeem.
Turbo, on machines that offer it, sells each pull back automatically at the buyback rate the moment it is drawn. You get USDC instead of the card.
The keep-or-sell call compares the buyback with the card’s last sale, or its Alt.xyz Value when there is no sale, after a 2% selling fee. It is arithmetic, not advice.
