Four concepts drive everything in BaseFit. Understand these and the rest of the docs will click into place.
Sneaker NFT
The item you equip to earn. An ERC-721 with on-chain attributes that set your earning rate, luck and durability.
Energy
Your daily earning budget. Each activity consumes energy; it refills over time. No energy, no rewards.
Durability
Sneaker health. It decays as you move and is restored by repairs. Higher durability keeps earnings at full rate.
Rewards
What you earn — paid roughly 70% in USDC and 30% in BFIT, scaled by energy spent and your sneaker.
Sneakers
Every earning session requires an equipped sneaker. Sneakers come in five types and several rarities, each with four base attributes — Efficiency, Luck, Comfort and Resilience. They level up, can be upgraded, and accept gems for stat boosts. See Sneaker Types and Attributes.
Energy
Energy is the core balancing mechanic. It caps how much you can earn per day so the economy stays sustainable. Each activity type has an energy cost per unit of time:
| Activity | Energy cost |
|---|---|
| Walking | 0.5 / 10 min |
| Running | 1.0 / 10 min |
| Cycling | 1.5 / 10 min |
| Swimming | 2.0 / 10 min |
| Gym workout | 1.0 / 30 min |
Energy regenerates over time, and your maximum energy grows as you own and upgrade more sneakers. Full mechanics live in Rewards & Energy.
Durability
Each session reduces your sneaker's durability. As durability drops, so does your earning efficiency — a worn sneaker earns less. Spend a small fee to repair it back to full. The Resilience attribute slows durability decay.
Rewards
When a verified activity ends, your reward is calculated from energy spent, your sneaker's attributes, and your share of the network. Rewards are paid mostly in stable USDC with a smaller BFIT component.
