kaiak-wallet's Issues

Deeplinking

Add Deep linking.
Ideal case: nano://nano_3wm37qz19zhei7nzscjcopbrbnnachs4p1gnwo5oroi3qonw6inwgoeuufdp?amount=1
Still fine: app://nano/nano_3wm37qz19zhei7nzscjcopbrbnnachs4p1gnwo5oroi3qonw6inwgoeuufdp?amount=1
Maybe it is only possible to link with app:// and not with nano:// in that case, we have to use app, even though it is not the best case scenario.

Prevent "backspace" in input fields to pop history

Currently when developing now and using input field with keyboard, a 'backspace' press will pop history and "go back".

Backspace not working in all input fields

Probably related: https://stackoverflow.com/questions/60890475/backspace-doesnt-work-in-number-input-field-kaios-svelte3

Keep display on while using QR code

Disable turning off display when the QR is shown. If possible, of course.

Don't hide top status bar

The top status bar with battery status etc. is hidden. I guess this has something to do with the toast. It should be visible.

Back-press on account overview throws exception

We should clear state after "unlocking" so that it's impossible to go back.

Research: Export encrypted Seedfile

Whatsapp, Facebook? Something accessible for the user. Find out what options users have.

We need storage functionality with some base security

Relates to #1

Make app work on device

Somewhere along the lines we broke old firefox compatibility: #20

Need to fix that somehow!

Figure out how to handle feedback to user on wrong input, errors etc

Opening app first time in kaios and click an account results in white screen

Closing the app and opening again works though.

Add PIN security

Add PIN for security

Looking at account, popping state should reflect new state

When I am in the transaction history, update and get a tx added and go back, the state isn't updated.

Add KaiAds to about page

Preserve storage on restart

It seems we lose local storage on restart. Are there alternative storage methods? Related to #45

Push menu to history

When the user selects the menu, it doesn't get pushed to the history. Therefore, the user is not able to return back after they selected something in the menu. The menu should be included in the history.

Keep wallet account in sync with wallet state

Comment from #56

When receiving funds and updating the wallet with the update button, the amount in the top doesn't get updates, but the transactions does

PIN + QR Code for two factor authentication

PIN + QR Code in order to make a cheap multi factor authentication system.

Core logic for send / receive

Implement core logic for sending and receiving funds.

Support basic keyboard navigation

Figure out what to do on these keyboard presses:

• ArrowUp -> Select element before
• ArrowDown -> Select element after
• ArrowLeft -> Go back
• ArrowRight -> Select nav element, get to supmenu etc.
• Backspace -> Go back
• Enter -> Enter middle menu item
• SoftRight -> Enter right menu item
• SoftLeft -> Enter soft menu item

Transactions not updated

Receiving Nano via QR Code -> Go back -> Transactions -> Updates (repeat)
It will not show the transactions, but when you go back and to transactions again, the tx is there.

Keyboard not reactivatd on app close → open

Add ESLint

I just recognized that I use { name } while you use {name}.
I am not strongly opinionated on this. But I guess it makes sense to have a common style rules on that. So, adding ESLint makes sense, I guess.

Add Configuration Menu and View

Add Localization

Move to https://github.com/kaios-design/gaia-l10n for texts

• Use localizationKey instead of title etc. in views, headers etc.
• Use localizationKey instead of primaryText in order to resolve the text accordingly

When adding account, require account alias

Comment from #56

Receiving 0.000001 shows 0.00000

Just a minor issue. The minimum amount you can send in Natrium is 0.000001.
When sending this to the KaiOS wallet, it just show 0. Maybe we should make it dynamic. So, that the sub 1 adapts to the highest depth ever received/send.

Load transactions from Node

This is a first step for communicating with a Node (and nice to do before send/receive).

Fix UI scrolling issue

See this stackoverflow question for more suggestion what might work.

Fix security issues

There are a couple of vulnerabilities in our dependencies. They need to get fixed.

Better handling of QR scanning

• Fullscreen - view / height ratio
• Loading on scanning screen
• Feedback when capture fails

Research: Contact list

Check, if it is possible to have a contact list system. Where is it possible to attach addresses to specific contacts and identify incoming and outgoing transactions.

Import wallet

It must be possible to import wallet from SEED / mnemonic.

Update function without losing the seed

It probably would be annoying for the user to backup the seed and import it again after a backup. So, there should be some mechanism to update without losing the seed.

Menu not scrollable

Similar to #44. To keep track of it.

Add icon for the wallet

Here's the general guidelines: https://developer.kaiostech.com/design-guide/launcher-icon

Add texts to navigation

Add texts to navigation, so that the user is able to scroll over it.

Input address with QR code

We need some way of inputting address with QR code!

Download localizations

In order to reduce the size of the app localization needs to get downloaded dynamically. Find and implement a way how to handle this mechanism. When the user opens the app for the first time, it should download the required localization and caches it. When the user is offline there needs to be an error message with the information that there is the need to get connected to the Internet, in order to download the localization file.

Add Typescript

Fix scrolling to update

When scrolling to update, the button isn't visible. Fix it.

Remove Secondary

Remove Secondary and implement functionality in ListElement

Storing text in transaction

There is this small trick/hack to store text in the raw value. Do we want to use this trick to support small texts in a transaction?

Bundle CSS

Implement toasts

Implement toast notifications.

Move css into components

Add Balance API

Add API interface for getting balances, instead of fake data.

Implement dpow

Need to apply for api key so that we can use https://dpow.nanocenter.org/

• Apply for Key
• Implement

Possible to configure representative

Both with address, and a predefined list?

Creating seed, loading not always showing

Seems to be a timing issue, happens more than not on kaios, and never on desktop 🤔
