Do you mean the dropdown menu with the list of coins? That's built from an API call to the service to query the supported coins and adding/selecting three hardcoded coins. The latter can be configured on `nrs.settings.js`. ---

Yes. I want to know which file is the list of all the coins in the list. I will place the Changelly Api key and list it in my own coin project. ---

Hello Sergi. I got a message from "Changelly" ("Could you please kindly provide me with the ETA on integrating Changelly API?" ). What do I need to send? (Estimated time approximately) is she asking this? ---

ETA traditionally means Estimated Time of Arrival, or finish time of journey (estimated=approximately), so yes they are asking when will the Changelly API integration be finished (your best estimate) Not sure what you need to send ---

Thanks Sergi. [TimmyTendies] answered. I asked what ETA means. I have one more question for you. Changelly sent me Api Key. I placed it in (nrs.settings.js). I am getting the error ( Changelly generateAddress error -32603 An error encountered during address generation. Please try again later.) on swap. Could it be because Changelly didn't activate the Api key? ---
