This is not yet wallet release - this is pre-release. It's Alpha, main functions work hopefully but not everything. Please don't send more money than you are willing to lose! If you are afraid - don't use it, wait for official full release. https://github.com/webchain-network/webchain-wallet/releases, main things that we know that don't work yet
1) It doesn't show incoming transactions, only outgoing, although It does show correctly total balance. Sending money works fine, so if you want to see incoming transaction details, you should use explorer for now
2) few things in interface doesn't work as it should, feel free to share it, although we know about most things probably.
You can use Mainnet in right upper corner but be careful as this will slow down your PC during network synchronization, so you might prefer to use light node mode.
Although we do encourage you to run full node of course if your PC can handle it.
