CARD
field manual

Two tokens enter. One pile pays.

CARD settles on relative return, not price. Whichever side moves further from its own opening mark takes the other pile, minus rake. Everything below is the whole rulebook.

step 01 · list

Anyone posts a pair from the whitelist and bonds it.

One pair per season slot. Lister keeps 15% of rake, released after 72h.

the verdict

Each side gets an opening mark at t0 and a closing mark at t1. The relative return of a side is its own move, so a $400 token and a $12 token are compared on equal terms:

r = (p1 − p0) / p0
Δ = (rA − rB) × 10000

If Δ > +ε side A wins. If Δ < −ε side B wins. If |Δ| ≤ ε the bout is a push: both piles come back minus the push fee. A missing or stale mark on either side never produces a guess — the bout is voided and every entry is returned whole.

One pair can only have one live bout at a time. Listing costs a 0.05 ETH bond and pays the lister 15% of the rake, claimable for 72h after settlement.

A side of a bout is one Stock Token from this list. The hold buys only 60% HOODX / 40% SPYX.

Until the on-chain Stock Token feed adapter is deployed, the reference mark is the underlying equity price from a public market feed. Every screen that shows a mark says which one it used.

what is not built yet
  • No contracts are deployed. Piles, rake and payouts are recorded in the protocol ledger, and the addresses above stay empty until they are real.
  • The Stock Token oracle adapter is not wired, so marks come from the underlying equity feed and are labelled as such everywhere.
  • No convert router is whitelisted, so conversion is priced at the oracle cross with no modelled slippage instead of a fake fill.
  • There is no fabricated volume, leaderboard or holder count anywhere in this app. Empty means empty.
