Note Keys is live (and very much in Beta) for /veil 
 
Docs on how to use it to follow shortly - but if you know how this works. Feel free to give it a go.

- Note keys address does not need gas and should not be your main wallet. These keys (a public + private Ethereum wallet) are used to encrypt and decrypt your note. 

- Notes are stored onchain using your normal web3 wallet you use for Veil with a tx.

- Manual upload only for now - will integrate in the deposit flow once some feedback / initial bugs sorted.

- Bunch of site improvements too.
