I'm trying to build a colored coin wallet using NBitcoin and any block explorer. The thing is that I can use any block explorer for almost every functionality of the wallet besides asking for my balance in colored coins. What are the ways to get the balance of an address in colored coins if not using CoinPrism API?? If I'm not wrong every other block explorer like BlockTrail, Blockchan.info or Blockr do not let me to do that.
Another question is related to the structure and components of a web or hybrid wallet. I recognized the following main components:
* Library for Key Management and Signing (NBitcoin, BitcoinJS, BitcoinJ)
* Block explorer to interact with the network and publish transactions
Is that correct? What other components shouls I take into account for the development of a colored coin wallet?
Please let me know if something is not clear.
Thanks in advance!
