Villera

Villera adds biome-adaptive banks and market districts to villages, so the buildings fit the biome they generate in. Villages with this content are rare in the Overworld, since the mod places them at a low rate during world generation, and the village structures are built into normal village generation.

Player accounts persist between sessions. Currency exists as physical coins and banknotes, and deposits and withdrawals take inventory space into account. Each bank card is bound to its owner, and transactions are rolled back when a failure would otherwise lose item currency. Separate Banker and Mineral Exchanger roles split the work at the bank, and the mod includes chunk rentals and stacked spawners that the author describes as performance-friendly.

Villera is a Fabric mod for Minecraft 1.21.11, released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, and it is not open source. Either side can run it, and neither needs it. The author notes that it works in single-player and on multiplayer Fabric servers, and that it is part of the Yufuus Mods family of expansions.
