Why did you pick Ethereum instead of Ripple or Stellar? They have lower transaction fees and almost instant transfers in the seconds while their token contracts are way easier to setup and maintain if you are thinking on adding EUR, GBP, YEN, etc in the future. The only real advantage of Ethereum is their user base which is important but not the only decisive factor.
We considered a wide range of platforms before making a decision. At this point, however, Ethereum is really the only viable option particularly from a security and wallet support perspective. That said, we have been developing the technology in such a way that it can be adapted to other blockchains in the future should CENTRE choose to do that. However, while incredibly important, the contract implementation isn't nearly as much work as the legal, operational, risk and audit components necessary to connect the traditional financial system to cryptocurrencies in an open and compliant way. Should CENTRE choose to provide an implementation on another blockchain, much of those other components would simply apply with little modification.
Note I have no affiliation with Circle or Coinbase.
Ethereum tokens have far wider support among industry players and consumers, and a far larger set of compatible applications (e.g. state channel networks that allow near-free and instant ERC20 transactions, like Celer).
>>while their token contracts are way easier to setup
Setting up an ERC20 contract is literally a copy, paste, brand and broadcast job. In any case the technical cost of setup is not a factor that's relevant to large companies.
