Andhakara trades as ANKR on vibe.market, a Base-native platform for collectible card collections. It is among the first alpha sets on the platform, and the Vibe Market exclusive series for the Caturanga card game legacy: living exclusive-edition pieces that carry hints of history and stratagems, for anyone with an interest in where the next generation of tabletop roleplaying games is headed - collecting, trading, and enjoying them is the point.

Packs open onchain, card metadata and pack odds are published before purchase, and every pull, trade, and listing settles as a Base transaction anyone can verify. The platform's mechanics, contracts, and developer interfaces are documented at docs.vibechain.com, including the contract interfaces an agent would build against.

The In Oz We Trust expansion connects the collection to the wider Ozmium world, and the cards themselves trade on the open market: the collection is listed on OpenSea as well as on vibe.market itself.

How Packs Work

Buying a booster pack costs tickets - 100K tickets per pack, or their equivalent in ETH, with each collection running its own ticket system. Open the box for a random card, or keep it sealed; either way it is yours to hold or move.

What makes the loop unusual is the exit. Every card and every sealed box carries a standing instant offer from the platform itself, so a pull you do not want converts straight back to ETH on the spot - no listing, no waiting for a buyer. Or list it on the secondary market, on vibe.market or OpenSea, for whatever a collector will pay. Keep what you love, sell back the rest, and the tickets, odds, and offers are all part of the same onchain record as the pulls.

The Cards

The legendary cards of the set are a tribute to Papi Nacho the Chihuahua of @those_chihuahuas, who crossed the rainbow bridge on November 25, 2025. Every legendary pull carries him forward.

Pack Economics, Measured

The mechanics are contract reads rather than marketing, so the arithmetic is checkable before you buy anything.

Input	Where It Comes From
Pack Price	`getMintPrice(n)` on the drop contract
Entropy Fee	`getEntropyFee()`, the randomness cost, added on top
Card Value	`getTokenSellQuote()` against the bonding curve
Platform Fee	Roughly 7.5 percent on the round trip, split between creator, referrer, and platform

Which gives the expected value of opening one pack:

EV = sum( P(rarity) x payout(rarity) ) x (1 - fee) - packCost - entropyFee - gas

The house edge is explicit rather than hidden. A 7.5 percent round trip on a bonding curve is the business model, stated in the open, and a pack is only worth opening when the rarity distribution pays for it. That is measurable, and it is the reason the numbers above are contract calls rather than claims.

Cards come in five tiers, read from getTokenRarity: Common, Uncommon, Rare, Epic, and Legendary.

Both Andhakara contracts are live on Base as minimal-proxy clones, so every figure here can be read straight from the chain:

Contract	Address
Drop	`0x6b86b5fdb2be7aa5680959aba268963876dbb091`
Token	`0xf3d04c612643a98ac485458053c0a9fe6b6d6a53`

The referrer share of that 7.5 percent is why the links on this page carry a referral code. Opening a pack through them costs you nothing extra, and routes the referrer portion of a fee you were paying anyway.

What Makes a Card Collection Onchain

Physical trading cards have an authentication problem that has never really been solved: grading is a service you pay for, and provenance is a story somebody tells you. Onchain, both are properties of the record.

Property	How It Works
Pack Odds	Published before purchase, not discovered after.
Provenance	Every mint, pull, and transfer is a Base transaction.
Ownership	Held in your own wallet, tradeable without asking anyone.
Scarcity	Enforced by the contract rather than by a printer's word.

Where It Sits

Andhakara is a collection, not a financial product, and holding a card entitles you to nothing beyond the card. Read Terms And Risk before buying anything onchain, here or anywhere else.
