It works well with other blockchains like Ethereum so I can send ether from my own blockchain right into another chain without having problems of gas costs etc.. The UI could be improved as there are some things that aren't clear enough in terms what they mean (like transaction fees). If you want interoperability between different chains this one will work very good! Using Etherium contracts we're able transfer ETH onto our project where people have access via an API key which allows them use their funds easily through any browser by just typing "openChain".
