- Live reference: https://pokehood.world/
- Typical timeline: 8-10 weeks

Snappy removes the manual work from farming. A user deposits any supported token and the platform automatically converts it into a SNAPPY/BNB LP position, applies impermanent loss protection and pays a fixed APR over a defined lock period.
