ERA SMP is a Java/Bedrock compatible server with a barter-based trading approach instead of a money system, encouraging players to set up barter centers and trade directly. It also features a leveling system, with paths that mention miners, potion brewers, and fighters who can allocate skill points into a weapons/armor skill tree. To protect builds, ERA SMP includes a claims system aimed at preventing griefing. The world is intended to never refresh, so there are no planned map resets, and the server notes that upcoming updates and biomes should remain accessible, alongside a developing End-themed focus.
