Buildings & Chains
Buildings are NFTs that generate Yield Points (YP). Each building belongs to one of four chains, each offering unique bonuses.
Chain Overview
There are four building chains in FuelCraft. Each chain has its own progression path from Tier 1 through Tier 4, with increasing YP and unique chain-specific bonuses.
Industrial Chain
Industrial buildings reduce crafting time. The more industrial buildings you own, the faster your crafts complete.
| Tier | Building | Base YP |
|---|---|---|
| T1 | Workshop | 5 |
| T2 | Foundry | 15 |
| T3 | Factory | 40 |
| T4 | Megaplex | 100 |
Knowledge Chain
Knowledge buildings improve your upgrade roll outcomes, giving you a better chance at higher YP when upgrading items.
| Tier | Building | Base YP |
|---|---|---|
| T1 | Study | 5 |
| T2 | Library | 15 |
| T3 | Academy | 40 |
| T4 | Observatory | 100 |
Military Chain
Military buildings contribute the highest combat score, making your city more powerful in raids — both offensively and defensively.
| Tier | Building | Base YP |
|---|---|---|
| T1 | Barracks | 5 |
| T2 | Armory | 15 |
| T3 | Fortress | 40 |
| T4 | Citadel | 100 |
Residential Chain
Residential buildings provide balanced YP with no specialized bonus. They are the most straightforward path to increasing your yield share.
| Tier | Building | Base YP |
|---|---|---|
| T1 | Cottage | 5 |
| T2 | Townhouse | 15 |
| T3 | Manor | 40 |
| T4 | Palace | 100 |
Chain Bonuses
Each chain provides a unique passive bonus based on how many buildings of that chain you own:
- Industrial — Reduces crafting time by 3% per item (capped at 40%).
- Knowledge — Adds +2 YP per item on upgrade rolls (capped at +20).
- Military — Provides the highest combat score for raids.
- Residential — Balanced YP generation with no cap modifier.
