Head over to https://aion.network to learn about Aion and how it works, how you can use it, and the community that exists.
A wallet is an object that can be used to store Aion or ATS tokens. A wallet corresponds to either a private key or a seed phrase.
A vault is a single file that contains your AIWA-generated seed phrase, as well as any imported seed phrases or private keys. It is proprietary to AIWA at this time, but it does provide the easiest way to transfer your AIWA data to another instance of Chrome.
We have a page dedicated to that question at getaiwa.com/developers! You can also find more general information at https://aion.network/developers/.
First, have a look on the AIWA Github issue tracker. If the issue doesn't exist yet, feel free to create one.
Feel free to send an email to aiwa@getaiwa.com or Tweet at BlockX Labs detailing what and why and we'll consider it. Suggestions are always appreciated!
Just get in touch! BlockX Labs would love to help you out.
