This Witcher 3 Mod
For years, Geralt of Rivia has roamed the Continent as a master monster slayer, but a humble financier he is not. That changes with a brilliant new mod that finally gives The Witcher 3: Wild Hunt a realistic economic system by introducing a fully functional bank where players can invest their hard-earned crowns.

The “Bank System” mod, created by modder liludev, cleverly expands the role of the existing Vivaldi Bank in Novigrad. Instead of just being a currency exchange, the bank now allows Geralt to open an account and deposit his funds. Once deposited, the money isn’t just sitting idle—it accrues daily interest, growing his wealth over time.
The system is both simple and customizable. By default, the bank offers a 1% daily interest rate. This means depositing 1,000 crowns would earn you 10 crowns the next day. To keep things balanced, the mod includes a daily payout cap (default 200 crowns), preventing players from becoming impossibly rich too quickly. For those who want to tweak their financial experience, the mod allows adjustment of both the interest rate and the daily cap.
This addition is more than just a novelty; it has practical gameplay benefits. Earning money, especially in the early game, can be a grind. This mod provides a steady, passive income stream for completing contracts and exploring. It also acts as a safe storage system, protecting a portion of Geralt’s wealth from being lost if he dies in combat, particularly against city guards.
