A free mod for Valheim, by aedenthorn.

You might have also heard of the mod called Server Rewards. In this mod, the developers created a new UI for the game and gave every player a chance to get some in-game currency. All you need to do is log into your Steam account and install the mod. After you log in, you will be rewarded with in-game currency, either in the form of a reward box, which can be opened to get a random amount of gold and various items. The way the developers created the mod is very easy to play, even for people who have never played the game before.

You will not be able to access the rewards unless you log in to the server.
