Trade Fairness Checker

Every item value here comes from verified game data — no guesses, no scraped community estimates. Specifically:

• Crops: the in-game sell price (crop.baseValue) from src/data/crops.ts.
• Gear: the documented estimated value from src/data/gear.ts. Gear without a verified value is excluded from the trade pool.
• Pets: a rarity baseline (Common: 500, Uncommon: 2K, Rare: 8K, Epic: 25K, Legendary: 75K, Mythical: 250K, Divine: 1M, Prismatic: 5M). Pets don't yet have per-pet community values, so all pets at a given rarity share this baseline. Pet entries are labeled (rarity baseline) to make this clear.

Demand tier mapping (deterministic, derived from rarity):

Fairness formula:

yourValue = Σ (item.currentValue × quantity) for items you give
theirValue = Σ (item.currentValue × quantity) for items you receive
yourDemand = Σ (tierWeight × qty) ÷ Σ qty (S=5, A=4, B=3, C=2, D=1)
theirDemand = Σ (tierWeight × qty) ÷ Σ qty

adjustedYours = yourValue × (yourDemand / 3)
adjustedTheirs = theirValue × (theirDemand / 3)

ratio = adjustedYours / adjustedTheirs

ratio ≤ 0.91 → You Win (you receive >10% more adjusted value)
0.91 < ratio < 1.11 → Fair Trade
ratio ≥ 1.11 → You Lose (you give >10% more adjusted value)

Honest disclosure: this tool does not yet ingest live community trade prices. Demand tiers are derived from rarity, not from community sentiment. When we add verified per-item community demand data, this page will be updated and labeled accordingly.
