}Off-Ramp
Initiate Off-Ramp
Start an off-ramp transaction to sell crypto for NGN.
Custodial flow (walletId):
- Crypto is automatically debited from the Zet wallet
- If source is not CNGN, it’s swapped to CNGN first
- CNGN is sent to the off-ramp provider
- NGN is deposited to the user’s bank account
- You receive an
offramp.completedwebhook
Non-custodial flow (sourceAddress):
- Returns a
depositAddresswhere the user must send crypto - Once received, same process as custodial
