Zenless Zone Zero Version 3.0 New Eridu City Fund Guide: Rewards, Plans, Dates, and Level Progression
The New Eridu City Fund returns in Zenless Zone Zero Version 3.0 with new rewards, premium upgrade options, and exclusive collectibles. Players can earn valuable resources simply by increasing their City Fund Level throughout the event period. While every player automatically receives the Basic Plan, upgrading to the Growth Plan or Premium Plan unlocks additional Polychromes, exclusive cosmetics, upgrade materials, and other high-value items.
Running from the Version 3.0 update until July 27, 2026, at 03:59 (server time), this season’s City Fund offers one of the most consistent ways to collect progression materials while completing regular gameplay activities. Players who plan to strengthen multiple Agents or W-Engines will benefit the most from completing Expansion Tasks and leveling their Fund before the season ends.
At Animon Life, seasonal updates like the New Eridu City Fund often generate increased interest among players following official Zenless Zone Zero content and licensed merchandise tied to major game updates.
Version 3.0’s New Eridu City Fund introduces three progression plans, exclusive cosmetics, and valuable upgrade materials. Every player starts with the Basic Plan, while the Growth Plan and Premium Plan unlock additional rewards, including Polychromes, exclusive avatars, namecards, W-Engine materials, Hamster Cage Passes, and menu decorations. Players must reach City Fund Level 30 to obtain the time-limited Great Builder’s Certificate before the event ends on July 27, 2026.
Version 3.0 City Fund Event Dates
The City Fund is available throughout most of Version 3.0 but has separate purchase and reward deadlines. Players should pay close attention to both dates to avoid missing premium upgrades.

Although purchases close one hour before the event ends, players can continue completing Expansion Tasks and claiming unlocked rewards until the event officially concludes.
Every Player Starts With the Basic Plan
The Basic Plan is automatically unlocked for every account at the beginning of the City Fund season. No purchase is required to begin progressing through the reward track.
Players increase their City Fund Level by completing Expansion Tasks, which award City Fund experience. As levels increase, additional rewards become available for collection.
This system functions similarly to a seasonal battle pass, rewarding consistent gameplay over several weeks.
Growth Plan Adds Premium Rewards
The Growth Plan immediately unlocks premium cosmetic and currency rewards. Purchasing this upgrade grants players several exclusive items before they even begin leveling the Fund.
Upon unlocking the Growth Plan, players instantly receive:
Polychrome ×680
Exclusive avatar “Focus on This!”
Beyond these immediate rewards, the Growth Plan also opens a premium reward track that becomes available as City Fund Levels increase.
Players who enjoy collecting exclusive profile customization items may find the avatar especially appealing since it is only available through this City Fund season.
Premium Plan Includes Additional Exclusive Items
The Premium Plan expands on the Growth Plan with even more exclusive rewards. Players who already own the Growth Plan can purchase a Plan Upgrade to unlock the highest reward tier.
The Premium Plan immediately grants:
Additional Polychrome ×208
Exclusive menu decoration set
W-Engine Microcontroller Unit
Resonating Core
Ether Batteries
These items provide both cosmetic customization and valuable progression resources, making the Premium Plan attractive for players investing heavily in Version 3.0.
Exclusive Rewards Unlock Through City Fund Levels
Raising your City Fund Level remains the primary way to earn the season’s best rewards. Simply purchasing a premium plan is not enough—players must actively complete Expansion Tasks throughout the event.
Major Rewards Available
| Reward Category | Available Items |
|---|---|
| Currency | Polychromes |
| Cosmetic Rewards | "Focus on This!" Avatar, "The Truth of the World!" Namecard, Menu Decoration Set |
| W-Engine Materials | W-Engine Microcontroller Unit, Resonating Core |
| Character Progression | Hamster Cage Pass, Ether Batteries, Upgrade Materials |
| Flexible Rewards | Selectable upgrade material types |
| Special Reward | Great Builder's Certificate (Level 30) |
Many of these resources are normally time-consuming to collect, making the City Fund one of the most efficient progression systems in Version 3.0.
Reach Level 30 to Earn the Great Builder’s Certificate
City Fund Level 30 unlocks one of the event’s most valuable exclusive rewards. Players who own either the Growth Plan or Premium Plan can claim the Great Builder’s Certificate after reaching this milestone.
However, HoYoverse confirmed that the certificate is time-limited.
Important details include:
Only available during the current City Fund season.
Does not carry over into future City Fund periods.
Expires automatically if unused before its deadline.
Players should therefore claim and use the certificate before the event concludes.
Expansion Tasks Drive Your Progress
Completing Expansion Tasks is the fastest way to increase your City Fund Level. These tasks award the experience required to move through the reward track.
Because every level unlocks additional rewards, regularly completing available objectives throughout Version 3.0 provides the greatest overall value.
Unlike event-specific combat challenges, Expansion Tasks naturally encourage players to continue participating in normal gameplay activities.
Should You Upgrade to the Premium Plans?
The best plan depends on how actively you play during Version 3.0. Casual players may find the free Basic Plan sufficient, while dedicated players who expect to reach Level 30 can maximize rewards by upgrading.
The Growth Plan is ideal for players primarily interested in Polychromes and exclusive cosmetics.
The Premium Plan offers additional long-term value by including progression resources such as W-Engine materials, Ether Batteries, and exclusive menu decorations.
As major seasonal updates introduce exclusive cosmetics and collectible items, licensed retailers such as Animon Life often see increased community interest in official Zenless Zone Zero merchandise connected to new character and event releases.
Tips to Maximize City Fund Rewards
Consistent participation provides the highest return. Rather than waiting until the final days of the event, players should complete Expansion Tasks regularly to avoid rushing progression before the deadline.
Keep these strategies in mind:
Complete Expansion Tasks Frequently
Finishing available objectives each week helps maintain steady Fund progression.
Purchase Before the Deadline
Players planning to upgrade should purchase the Growth Plan or Premium Plan before July 27, 2026, at 02:59 (server time).
Reach Level 30 Early
Unlocking the Great Builder’s Certificate sooner gives more time to use the reward before it expires.
Final Thoughts
The Version 3.0 New Eridu City Fund remains one of Zenless Zone Zero’s best seasonal progression systems. With free rewards available to every player and premium plans adding exclusive cosmetics, Polychromes, W-Engine materials, and upgrade resources, the event offers value for both casual and dedicated players.
Reaching City Fund Level 30 before July 27, 2026 is especially important for anyone hoping to claim the limited-time Great Builder’s Certificate, while early plan purchases ensure access to every premium reward tier throughout the season.
Animon Life continues to follow and update official merchandise releases like this for North American customers.
