Exactly that's why it's advisable to download the official wallet, it makes the network so much better if everyone who's using nano or who has nano will keep a node running, it really helps in making the transactions of nano super fast. Yeah you're right even though nano isn't a staking coin it can really help the community if everyone takes time and download the official wallet. Is nanovault.io from the official team? It's the first time that I heard about it, I doubt it's created by the official dev team, I could be wrong though. I hope somebody can confirm. Yeah the official wallet is definitely the safest when it comes to storing your nano but sadly it's not everyone's cup of tea and I think the official wallets that's been provided by the team is also safe and can really secure your nano as well.
This wallet is not maintained by the devs. Here is it's github if you are interested and want to investigate into it further
https://github.com/cronoh/nanovault. So far I have tested it and it works. Devs are currently working on mobile implementations and I am not sure if they have anything planned for lightweight wallets for Desktop.
Oh it's not? Then better stay away from it though, it's quite risky to use a wallet that's not being maintained by the devs but if you have the private key then maybe this site is safe, so far is it any better that the official web wallet? How's your experience so far, does it seem safe to use?. I'm pretty sure they already have that planned but right now they're focusing on the mobile wallet first because it's more convenient to a lot of users and in all honestly having a mobile wallet can really attract a large number of people. I think in their roadmap the team mentioned that there will be a light wallet released by the end of this year. Honestly I can't wait to use the mobile wallet, I heard it's lightning fast and super light weight, I hope they can meet all of the community's expectations.
