How Slabdex works

Slabdex is a gacha trading-card game on Solana. Every coin on CoinGecko is a card. You summon packs of 5, each card arrives graded and sealed in a numbered slab with the coin's market cap at the moment you pulled it, and every slab you hold scores points on a weekly leaderboard.

A card's tier is set by the coin's market cap at the moment you pull it. The tier fixes its grade, its stars and the points it scores.

Both are used in duels. Every slab has a public certificate page: its number, pull date, origin, owner and the coin's live data.

• Serial number. Every slab gets the next number in the Genesis series (#018233), for good.
• Edition. The certificate shows which pull of that coin it was: N° 3 of 12 means the third slab ever pulled of the coin, out of twelve so far.
• 1st pull seal. The very first slab of a coin wears a gold seal, once that coin has at least 2 slabs.

A summon gives 5 slabs. Cards 1 to 4 are mostly C and UC; card 5 is always R or better. At Basic odds a Legendary lands 0.32% of the time, about 1 in 313. Bigger packs are paid by burning $SLAB: the tokens are destroyed for good. Prices are a fixed share of the 1B supply.

Opening is a show: tear the pack, flip the slabs one by one, and the rarer the louder. The last slab climbs the ladder live: R locks first, then it tries each higher tier and stops on its real rarity. The pull is drawn on the server before the show starts, so the animation never changes the result.

Odds are per pack. Free, mission and duel packs use Basic odds. Full slot-by-slot odds →

Three missions a day, the same for everyone, reset at 00:00 UTC. There is always a summon to open; the other two rotate day by day among these. None of them needs $SLAB.

• Win a quiz duel
• List a slab on the market

Pick 3 cards. Each one faces a random coin of the same rarity, and you answer one question about the pair: which has the bigger market cap, which trades closer to its all-time high, or which has the higher price per token.

• 12 seconds per answer.
• Win 2 rounds out of 3 to earn 1 free summon.
• 3 duels a day. Your slabs are never at stake.

34 cases, each holding one card drawn from a themed pool: a blockchain, a narrative, a rarity band or an era. A case is priced at the expected value of its card, rounded up, and paid by burning $SLAB. A pool rich in big coins gets better odds on high tiers, and costs more.

Value of each tier, in $SLAB, used to price every case.

The risk label shows how spread the outcomes are. Low risk pays close to the price every time; high risk means mostly cheap pulls with a rare jackpot. Every case page lists its odds and the biggest coins of each tier.

The Inventory, at the right of the menu, holds everything you own: your slabs, the packs waiting to be opened (free summons, reward packs, Premium gifts) and your rewards.

Fusion: 5 slabs of one rarity become one slab of the next rarity, a random coin of that tier, plus a small $SLAB burn once the token is live. Legendary is the top: it can't be fused. Fusion fills your dex, it never adds points: 5 slabs always score at least as much as the one they become.

Re-grading: a slab keeps the market cap it was pulled at. If the coin has since grown into a higher tier, you can re-grade the slab to it for half the difference in value between the two tiers, burned. Grades only ever go up.

List a slab at any price from 1,000 to 100M $SLAB and cancel any time, unless a buyer is paying. Buying opens at the $SLAB launch; listing is open now.

Market payments go to the seller: unlike summons and cases, they are not burned.

Every slab you hold scores the points shown in 03. Each week, 80% of the token trading fees go back to players, paid in SOL: half to the top 4, pro rata to their points, half raffled among every other collector, one ticket per 10 points, 10 winners. Winners receive SOL straight to their wallet, and the draw seed is published. Points count what you hold right now: selling a slab takes its points with it.

Holding $SLAB in your wallet boosts your points and refills free summons faster: 100k+ ×1.1, 1M+ ×1.25 (a free summon every 8 h), 10M+ ×1.5 (a free summon every 6 h). The balance is read at the weekly draw.

$SLAB launches on pump.fun with a supply of 1B. Summons and cases burn it, so every purchase shrinks the supply; marketplace prices are paid in it, from buyer to seller. Token trading fees are collected in SOL and split two ways; the player rewards are paid out in SOL every week:

The 5% marketplace fee goes to the protocol.

• Market data comes from CoinGecko, refreshed about every 10 minutes for the big coins and in rotation for the rest of the catalog.
• Pulls use server-side cryptographic randomness, drawn only after your purchase is confirmed.
• Burns and payments are checked on-chain. Each transaction can be redeemed once, and only by the wallet that sent it.
• The market cap at pull is frozen on the certificate, so a grade never changes.
