Zenless Zone Zero Trust System Guide: Max Rewards & Daily Farming

Introduction

Building strong bonds with your Agents in Zenless Zone Zero isn't just for story - it's a direct path to premium currency and exclusive rewards. The Trust system is a core progression mechanic, but navigating its events, caps, and priorities can be confusing. This guide breaks down everything from daily farming loops to max-level payouts, so you can efficiently turn friendships into Polychromes.

Understanding the Zenless Zone Zero Trust System

What is Agent Trust & Why It Matters

Trust is Zenless Zone Zero's friendship mechanic, which means every playable Agent has a personal bond meter that tracks how close they feel to you as the Proxy. Think of it as a relationship tracker that fills up as you spend time with each character, and unlike some gacha games, each Agent's Trust is completely independent of the others.

So why should you care? Well, increasing Trust yields some pretty sweet rewards:

• Polychromes (the premium currency you need for pulls)
• Dynamic Wallpapers for your phone interface
• Deeper story content and exclusive voice lines
• More entries in the Agent's Partner Archive

The system caps at Trust 4 for every Agent, and hitting that max bond is the only way to see their full story.

The 4 Trust Levels: Familiar to Trusted

The Trust grind breaks down into four distinct ranks, and each one gates specific rewards and content. Here's the full breakdown:

Rank 1: Familiar This is your starting point once you recruit an Agent. At this level, they'll start sending you DMs and can be found hanging around the neighborhood, but you won't get any materials yet. It's basically the 'we just met' phase.

Rank 2: Friendly Now we're getting somewhere. You'll need 4 Trust points to hit this rank, which means you'll find the Agent in more locations around town and they can work as a Video Store promoter. The rewards here include Polychrome ×20, Denny ×5000, plus 3 Skill Chips based on the Agent's Attribute. Not bad for just starting to get close.

Rank 3: Close This is where the investment starts to show. Requirements get a bit tricky here because S-Rank and A-Rank Agents have different thresholds. S-Rank Agents need 6 Trust points (10 total), while A-Rank Agents only need 5 points (9 total). The big reward here is the Agent-exclusive Resonium, plus you'll pocket Polychrome ×30 and another Denny ×5000.

Rank 4: Trusted The final level requires 6 more Trust points, bringing you to 16 total for S-Rank Agents or 15 total for A-Rank Agents. This is the big one - it nets you the Agent Live Wallpaper that you can show off, along with Polychrome ×30 and Denny ×5000 to round things out.

If you're doing the math, that's 140 Polychromes per Agent when you max them out, which adds up fast if you're building a full roster.

7 Types of Trust Events: Complete Guide to Each Method

1. Street (Random) Trust Events

These are the bread-and-butter random encounters you'll stumble across while exploring New Eridu. As you walk around, agent pop-ups appear - think of them as Wandering-Agent Encounters that trigger mini-conversations. The catch? There's a hard daily limit of roughly three in-game days, which translates to about 9-10 events before spawns completely dry out until the next server reset.

So you can't just mindlessly farm these forever. The smart move is using the Travel menu to spot agent silhouettes before you even start walking, that way you won't waste time wandering empty streets. The optimal daily route is pretty straightforward: start at Sixth Street, head to Bard Street, then swing by Lumina Square. Once you've hit those three zones, check the Travel menu again and directly invite any remaining agents you can - that's your maximum yield for the day.

2. Agent Invitation Events

Agent Invites are a whole different beast, and they open up once you hit Inter-Knot level 30 and finish the Chapter 2 Interlude. Unlike street encounters, each agent can only send you one invite per real-world day, and you'll receive these through the Messages app. The good news? These aren't subject to that harsh street spawn cap, which means they keep coming even after your random encounters run dry.

When you're actually in the hangout, picking the best dialogue choices (marked with a heart icon) grants +60 Trust XP, while neutral options only give +40. It's a noticeable difference that adds up fast, so you really want to aim for those heart responses whenever possible.

3. Quality Time Events (Version 1.4+)

Introduced in Version 1.4, Quality Time Events are basically the upgraded bonding system for newer agents, and this is where the real efficiency happens. You're looking at daily point goals of 60-120 points, and hitting that cap is the fastest way to max trust post-1.4 - we're talking roughly 25 days to hit 3,000 points.

There are two main types to focus on: Wish Events grant 50 Trust XP plus 40 Polychromes on first clear, and they count for 30 daily points. Fun Events are smaller but still valuable, giving 20 Trust XP plus 20 Polychromes and adding 20 daily points. The math is simple - if you can knock out both types daily, you'll cap that 120-point limit and watch your trust levels skyrocket.

4. Trust Rank-Up (Milestone) Events

These are the automatic cutscenes that trigger when you hit trust thresholds at 3,000, 6,000, and 10,000 points. Each milestone rewards 100 Polychromes, which means you're getting a total of 300 Polychromes per agent just for bonding consistently. The rewards don't stop there - you'll also unlock character-specific W-Engines, live wallpapers, and exclusive titles as you climb.

Reaching that final rank (Trust 4) is the big prize: it unlocks the agent's dynamic wallpaper and their partner archive entry. These events are guaranteed, no RNG involved, so they're basically free milestones you can plan around.

5. Story-Locked Character Quests

Some of the biggest trust gains come from story-locked events, but you'll need to put in the work first. These require completing the agent's Agent Story commission chain and specific Phaethon story chapters. For example, Soldier 11 unlocks additional Trust Events only after you clear Phaethon Chapter 3-1.

Each completed agent story commission dumps a hefty 200-300 Trust points into your pocket, which is way more than random street chatter. Even here, dialogue choices matter - optimal picks still grant +20 Trust XP, so you might as well choose wisely.

6. Commissions with Trust Options

Trust Commissions show up on the daily board with a handshake icon right next to the agent's chibi portrait, so they're hard to miss. Unlocking them requires sending DM invites to agents and finishing their story prerequisites first.

Here's a pro tip: you can force a commission to spawn by inviting an agent, exiting out to the street, then re-entering the VR lab. When you're actually running these, correct dialogue choices in the final nodes award +20-30 Trust XP, but even wrong choices still give you +10. It's basically impossible to walk away empty-handed.

7. Seasonal & Special Patch Events

These are the limited-time trust events tied to version updates and banners, and they're absolutely not permanent. They only appear during the version patch where an agent debuts - typically a 6-9 month window before any potential rerun.

For context, Version 2.5 runs from December 30, 2025, to February 5, 2026, which means any trust chains for Zhao must be completed before the 2.6 maintenance hits. Picking preferred dialogue options in seasonal events awards +20 Trust XP instead of the usual +10, and completing the final node grants a one-time bundle with 100 Polychromes, W-Engine modules, and a profile badge. Miss these, and you're waiting nearly a year for another shot.

Your Daily Trust Farming Checklist

Everything resets at 04:00 UTC+9, so that's when your daily timer starts ticking. The fastest way to knock out your trust gains is the 90-second street event loop - leave Random Play, pop over to the 6th Street arcade for the first white bubble, then fast-travel to Lumina Square north for the second, and finish at Brant Street alley for the third. That's three quick interactions that'll net you roughly 45 trust points split across whichever agents show up, and you're completely done with street events for the day.

After that, you'll want to tackle your three Work Orders and three Errands. These each drop trust items, but here's the key: always pick your target agent for the day. Errands alone dump +30 trust onto whoever you select, which adds up fast. The Work Orders are just gravy on top.

Now for the big one: Quality Time appointments. These unlock at Trust Rank 2 and award 60-90 trust plus some gift vouchers, but they'll cost you 30 Battery each. The good news? You can stack these after grabbing your daily free Battery from the VR headset, so you're not really sacrificing much. One date per agent per day is the limit, so spread the love if you're juggling multiple targets.

Your Weekly Trust Maximization Plan

The weekly rhythm builds on your daily grind but adds a few high-impact moves. Hollow Zero is your main weekly trust injection - clear it five times and you'll get trust item crates. The trust-per-minute isn't amazing compared to street events, but it's passive income while you're farming other materials, so you might as well.

The real game-changer is the Agent Invite system, which opens up after you finish Chapter 2 Interlude. You get three invites per day through the Contacts menu, and each agent can only be invited once per day on a 20-hour cooldown. Here's where it gets interesting: if you keep inviting the same agents consecutively, they'll start appearing on the streets for extra dialogue and even some hidden achievements.

When you're actually on the invite, always pick the top-heart (blue) dialogue option - that's the big trust chunk, anywhere from 40-60 points, and it'll trigger a 30 Polychrome pop every time you hit a Trust Rank milestone. Since Patch 1.5, you can bank up to three days of invites (nine total), which means busy weeks don't have to cost you progress.

Who to Focus First: Smart Agent Priorities

Here's the deal: not all agents are worth the same investment. If you're playing the meta, you want Yixuan (Ice DPS), Zhao (Fire DPS), Miyabi (Ether DPS), and Astra Yao (Support) at Trust Rank 4 as soon as possible - that's where you'll unlock 80+ Polychrome per agent, and that adds up to serious pull currency.

For everyone else, there's a clean breakpoint: push every agent to Trust Rank 2 to claim the first 80 Polychrome cache, then park them. Don't waste time going further unless they're actually on your main team.

The smartest move is to check who's closest to the next trust tier. Each milestone pops 30 Polychrome at Rank 2, another 30 at Rank 4, and 20 at Rank 6, so finishing someone who's 90% there gives you immediate returns. This is especially true for your main team members, since Trust Rank 2 unlocks trust-exclusive Resonium in Hollow Zero and live wallpapers for your profile.

If you want to get hyper-efficient, match your farming to the agent: run Daily Combat Simulations with Yixuan as your on-field carry for +15 trust per run, use Hollow Zero exploration for Zhao to grab +20 trust per zone cleared, and send Miyabi on 12-hour Investigation commissions for 30 trust plus 5 extra Polychromes. It's a bit extra, but it shaves days off your grind.

Trust Level 4 Rewards: What You Get for Maxing Relationships

Alright, so you've been spamming those Trust commissions and finally maxed out an Agent. Here's what actually hits your mailbox when you hit Trusted status - and yeah, it's worth the grind.

80 Polychromes Per Agent (But It's All At The End)

The main draw is the 80 Polychromes, which drops instantly once you reach Trust Level 4. No RNG, no hidden quests, just pure pull currency straight to your mail. But here's the thing: you don't get 80 at every rank. The payout only happens once, and only when you max the relationship.

Here's how the distribution looks across the ranks:

Trust Rank	Polychromes Reward
Friendly (Lv. 2)	20
Close (Lv. 3)	30
Trusted (Lv. 4)	80

So while you do get smaller chunks along the way, that final rank is where the real money is. If you're running the numbers, that's 80 Polychromes per Agent, which means your theoretical ceiling is whatever your roster size is. For F2P players, this is one of the biggest consistent pull sources in the entire game - maxing your whole cast is basically a free multi-banner's worth of pulls.

Your Agent Becomes Your Wallpaper

Currency is nice, but the real flex of Trust Level 4 is the Dynamic Wallpaper you unlock. Each Agent gives you their own live animated background you can equip on your main menu or phone.

• How to set it: Open Settings → Main Screen Wallpaper → Dynamic Wallpaper tab. Any Agent at Trust Level 4 shows up here automatically, no extra steps needed.
• The good ones: Ben's got that chill loop, Burnice's wallpaper is pure fire (literally), Anby's is a classic, and even newer Agents like Zhao have slick animations in their Trust 4 rewards.
• These aren't static images - they're full loops, so your menu actually feels alive instead of just sitting there.

The Extra Goodies Nobody Talks About

On top of the Polychromes and wallpaper, Trusted status comes with a care package that most people gloss over. You get 30,000 Denny and 3 Advanced Skill/W-Engine Chips specific to that Agent's Attribute. It's not game-changing, but it's a nice chunk of upgrade material that saves you a few stamina runs.

You also earn an Affinity Sticker - a chibi portrait or catch-phrase bubble of the Agent. You can plaster these on your Inter-Knot profile card or flex them in chat, which is perfect for showing off your favorites without saying a word.

And there's one more quiet bonus: collecting multiple Trust Level 4 Agents completes the Compendium mission 'Raise 3 Agents' Trust to Lv. 4,' which throws in another 50,000 Denny plus a profile title. It doesn't flash on screen, but it's there if you're tracking your missions.

Advanced Tips & Common Mistakes to Avoid

Dialogue Choice Optimization

Trust dialogue choices aren't as cryptic as they seem. The best options are almost always the supportive or empathetic ones, which means you can usually trust your gut when it feels like you're being a good friend. For example, when Ben hits you with his 'Bear's Duty' line, the optimal answer is 'A real teddy bear never abandons his squad' - that extra sincerity is what the system rewards.

Picking these friendly responses doesn't just feel good; it gives you maximum Trust EXP per interaction, which accelerates your rank progression significantly. If you're ever stuck or want to min-max, the community has your back. There are maintained spreadsheets and Game8's daily-update hub that list every Agent's confirmed optimal lines, so you can check before you grind.

Managing Daily & Weekly Limits

Here's where things get time-gated. Trust Events have hard caps, and if you don't plan around them, you'll waste a lot of time.

• You can trigger three full Trust Events per real-world day, but this is an account-wide cap - not per-Agent, unfortunately.
• The daily limit resets at server reset (03:00 UTC), so that's when your three-Event allowance comes back.
• Game8 confirms this is three per in-game day, so you'll need to keep track of both clocks.

Efficiency Mistakes Most Players Make

The biggest trap is pure RNG farming. Don't just wander hoping for events; instead, seed them by looping Sixth Street before 08:00 server time. You can also bypass the daily limit entirely by using Agent Trust Missions in the Video Archive, which is a game-changer.

Another common mistake is ignoring an Agent's Wish Destination. When Anby wants a Bunny Ride or Nicole craves Milk Teas, fulfilling these wishes gives you +25 Trust plus bonus gift boxes instead of the baseline +10. That's a massive difference you can't afford to skip.

Battery management trips people up, too. Don't burn it all on combat commissions - split it roughly 60/40 toward Hollow Expeditions that drop Trust Gifts, which you can gift for +20 Trust each.

Here's one that hurts: pre-leveling Agents to 35-40 before starting Trust. Keep them at Phase 2, level 30 max until Trust Rank 4, or you'll waste Dennies and Investigation Logs on disk-drive calibration you can't use yet.

And those green Quality Time SMS bubbles? That's free Trust. Answer the friendly chat within one real hour for an extra +10, because missed replies are a common loss that adds up fast.

Finally, stop grinding RNG Hollow runs when you don't have to. Weekly Officer Mewmew tasks and Godfinger Arcade high-score rewards hand out Trust Gift Selection Boxes that save you tons of time.

Character-Specific Trust Guides & Resources

Where to Find Agent-Specific Dialogue Answers

First things first: you need the answers. The best resource is a massive community Google sheet that Game8 maintains, and it updates within hours of every CN patch dropping. We're talking complete data for 45+ agents (including 1.3's Piper and Harrow), with every Trust Event location, the dialogue choice that gives you that sweet +20 Trust bonus, spawn cooldowns, and rewards. That's your bible right there.

While you're bookmarking that sheet, here are the clutch answers for your starter trio so you don't mess up early: tell Anby 'I'll stay and watch the movie with you.', call Nicole's plan 'actually clever', and challenge Billy to 'beat the high-score together.' These are simple choices, but they make a real difference in building that early rapport.

But none of this matters until you hit Inter-Knot Level 30 and finish Chapter 2 Interlude. That's when Trust Events become available globally. After that, you'll still need to clear each agent's specific story chapter before their events start spawning. So don't go hunting for Piper's events until you've done her story, you know?

Popular Agent Trust Farming Priorities

So who should you focus on first? The consensus is clear: start with Anby. She's the best 4★ stun engine in the game and actually scales with later W-Engines, which means she stays relevant. After that, prioritize Nicole since she's literally the only Ether support and basically has a permanent spot on any Ether team. Billy comes third, but here's the harsh truth - he falls off hard once you pull S-ranks, so don't over-invest in him.

Now for the F2P grind: you can buy three 500-Polychrome gift boxes each week from the shop, and that's it. This pace gets you one character to max gifts every 6-7 days, which sounds slow but it's sustainable. The golden rule? Never refresh the gift shop with Polychrome - it's a trap.

The real payoff hits at Trust-Rank 3 (around 5,000 points). That opens up the final Mindscape-Cinema slot and gives you 40 Polychrome per agent, which is enough to fund a 10-pull on the S-rank selector banner. So yeah, that's worth the effort.

New Agent Trust Unlock Requirements

Pulling a new agent is only step one; you can't just throw gifts at them immediately. There are three locks you need to break: first, obviously you need to acquire the agent, then you have to complete their specific Main Story Chapter (check the Partner Archive to see which one), and finally you need to hit the Inter-Knot Level requirement for their Trust Tier. For example, you won't get past Trust C without hitting Inter-Knot 30.

Speaking of those level gates, here's the full breakdown: F→E needs Level 5, E→D needs 10, D→C needs 20, C→B needs 30, B→A needs 40, and A→S demands Level 45. If you try to talk to an NPC and they tell you to come back later, this is why.

Your daily routine should focus on burning battery on Main Story commissions first since they give the biggest Inter-Knot EXP chunks. But don't skip those Agent Story commissions (the purple icon ones) because they reward both Trust progress and Inter-Knot EXP. It's the most efficient way to multitask your progression.

Conclusion

Mastering the Trust system is a marathon, not a sprint. By focusing on key Agents, optimizing your daily and weekly routines, and avoiding common efficiency traps, you can steadily unlock valuable Polychromes, dynamic wallpapers, and deeper character stories. Start applying these strategies today to build a stronger roster and a richer New Eridu experience.
