How could one make an AE smart contract that can control transactions on another blockchain wallet. The primary concern here are:
- How would one protect the private key that are used on the other blockchain?
- How would one transmit the transaction to the bitcoin blockchain?
The transmitting of the signed transaction seems easier. But protecting keys seems a problem. I suppose, if the second blockchain were Ethereum, then you could have a smart contract on Ethereum communicate back & forth with the AE smart contract, and then transacting coins from the smart contracts wallet - assuming smart contracts can hold coins.
