Ensuring Sustainable Horse Breeding Through a Dynamic Fee & Rarity System

Breeding in MetaHoof is a strategic investment balancing economic health, genetic integrity, and market engagement. Fees are determined by:

• Base Generation Fee
• Parent Rarity Multipliers

This model incentivizes thoughtful breeding while regulating supply and preserving rarity.

1️⃣ Base Breeding Fees by Generation

Generation	Base Fee (USD)
G1 (Genesis) Mint	$20 (fixed)
G2	$18
G3	$15
G4+	$13

2️⃣ Parent Rarity Multipliers

Each parent's rarity applies a multiplier to the base generation fee:

Parent Rarity	Multiplier
Common	1.0×
Rare	1.1×
Legendary	1.25×

• Total Fee = Base Fee × (Multiplier of Parent A) × (Multiplier of Parent B)

Example

For breeding two Rare parents for G2:

$$F=B\times m_1\times m_2$$

Where:

• (B = 18) (Base Generation Fee for G2)
• (m_1 = 1.1) (Multiplier for Parent A)
• (m_2 = 1.1) (Multiplier for Parent B)

Therefore:

$$F=18\times 1.1\times 1.1=21,6$$

Resulting in a final breeding fee of $21.60.

3️⃣ Offspring Rarity Probabilities

Parent combinations determine offspring rarity probabilities:

Parent Combination	Common (%)	Rare (%)	Legendary (%)
Common + Common	80	15	5
Common + Rare	70	20	10
Common + Legendary	60	25	15
Rare + Rare	50	30	20
Rare + Legendary	40	35	25
Legendary + Legendary	30	40	30

This probability model aligns breeding costs with genetic outcomes, encouraging strategic parent selection.

4️⃣ Strategic Benefits

• Supply Regulation: Higher fees for rarer parents curb over-breeding.
• Rarity Preservation: Probability model rewards combining rare lineages.
• Economic Incentives: Players weigh cost vs. potential offspring value.
• Market Dynamics: Diverse parent pairings stimulate marketplace activity.

Conclusion

MetaHoof’s updated breeding fee model leverages generation-based costs and parent rarity multipliers, underpinned by a probabilistic rarity table, to balance supply, preserve genetic integrity, and drive a dynamic breeding economy.
