CNGN
CNGN (cNGN) is a Nigerian Naira-backed stablecoin pegged 1:1 to NGN. It serves as the intermediary for all fiat on/off ramp operations:
- On-ramp: NGN → CNGN → Target Token (if not CNGN)
- Off-ramp: Source Token → CNGN (if not CNGN) → NGN
This means:
- Buying CNGN directly is the cheapest on-ramp (no swap fee)
- Selling CNGN directly is the cheapest off-ramp (no swap fee)
- Other tokens incur an additional 20 NGN swap fee for the CNGN conversion step
