Anyone have IEO launcher plugin or instruction to make IEO launcher?
Also banking gateway plugin?
What do you mean by IEO launcher? You just make a new market and place a sell order. There you have an IEO launcher I suppose.
For bank gateway integration look into this: https://docs.hollaex.com/how-tos/bank-integration
Note that you need to have the fiat gateway associated to you. Fiat master plan would give you that access.
