We are planning to open our product to the public for live testing. We want to support both Ropsten and Rinkeby networks, just in case.
When registering, each user should get around 10 ether on their account so that they can freely play around with the product. The product is an abstraction layer over a blockchain implementation, so we do not want users to have to deal with faucets in order to get it. Because of that, we would like to fill our main account with enough ether so that we can redistribute them to the users when necessary.
For Ropsten, that is easy because we can automate withdrawal from the faucet.
For Rinkeby that approach is not possible, because of the social network account limitation.
Do you know of any other way to get a one-time injection of larger amount of Rinkeby ether?
