How it works

The market is the meta

A mood oracle reads $BNBC/BNB price action and rewrites the game's economy in real time.

Every $BNBC swap triggers BnbCardsHook.afterSwap, which writes a uint8 mood to BnbCardsCore. That single byte multiplies expedition rewards, shifts pack rare-rates, and sets the per-direction trading fee. A whale buy doubles expedition rewards for 100 blocks (a halving in-game). A whale sell triggers FUD: rare-drop rates drop 10% for 100 blocks.

What makes it different

If any of these stop being true, BNB Cards is no longer BNB Cards.

Fully on-chain art

Every pixel of every card SVG is generated by the contract. tokenURI() returns a complete data URI. No IPFS, no centralized image hosting.

bolt

Trustless combat

the on-chain combat resolver is pure. Same decks always produce the same winner. No oracle, no commit-reveal, no signer.

currency_BNB Chain

Halving cycles

Every 210,000 blocks (~29 days), BASE_REWARD halves. The economy mirrors BNB Chain's identity: capped supply, predictable issuance.

hub

mood oracle integration

The mood meta is not a script. It is a PancakeSwap v2 hook. Whale buys trigger HALVING. Whale sells trigger FUD. The pool is the game.

grid_on

Pixel-art discipline

Strict 32-color palette across cards, UI, and animations. Every illustration is a 16×16 sprite at 12×.

key_off

No admin keys

No owner, no proxy, no upgrade path, no pause. The deployer renounces control before the first pack opens. The contracts are forever.

Stack your first deck

The contracts are deployed. The hook is wired. The first daily tournament starts at next entry-window open.
