All tokens are now implemented as a strongly-typed Contract, Erc20Contract, or Erc721Contract. This prevents having two separate lists of overlapping tokens/contracts and normalises how to retreive the current SNT contract (depending on the network).
Fixes: #926.
Gas estimations were not being decoded correctly (indicated with "error getting gas price predictions" in the console) and were preventing transaction dialogs from continuing past the step containing the GasSelector component. This affected mainnet only, because in testnet we have hardcoded gas prices (for when the gas prices on mainnet are insane) which is why it was not apparent in testnet.
fix: Contract address not showing correctly
This was caused by `getStickerMarketContractAddress` being moved to `utilsView` but not updated in QML
Closes: #586
Previously, loading sticker packs and stickers would show a lot of blank and non-interactive content.
Now, stickers and sticker packs have grey circles to indicate loading. Additionally, the sticker market button (+) shows a loading indicator until the sticker packs are loaded.
Supports system dark mode. Changes the user appearance setting to a 3-way setting of System, Light, Dark.
New accounts will have their appearance setting set to "System", which uses the system setting to determine if dark mode should be applied.
Breaking change: Users who had their settings on Light Theme, will now get the system theme (light or dark). Users who had their theme set to Dark, will now get the Light theme.
At startup, the onboarding screens will have the system-level setting of dark mode applied or not. Once, logged in, the user settings will be applied.
## Note
An appearance setting of "System" is not dynamic to the system-level setting. This means that if a user has "System" set for their appearance (and ie, the user has light mode set), and then user then changes their system setting from light to dark, the app will not respond until it is restarted. This is due to a limitation of Qt not having a reliable way to propagate these changes to QML.
Use nim-web3 library and remove internal encoding funcs that were copied from nim-web3.
Remove all instances of EthAddress (and therefore eth/common/eth_types imports)
Currently, exceptions thrown during transactions or gas estimation that were spawned in another thread are not being propagated, due to a limitation in nim (see https://nim-lang.org/docs/manual_experimental.html#parallel-amp-spawn).
This means any exceptions from status-go were not propagated correctly and would cause the app to crash. This includes entering the wrong password when trying to send a transaction.
The issue was addressed by passing a `success` variable by reference, which is set to false if an exception was thrown by status-go.
