Zenless Zone Zero (often shortened to ZZZ) is HoYoverse’s action‑RPG set in the futuristic city of New Eridu. Like many modern gacha‑style games, ZZZ uses premium currencies that help players progress faster, access exclusive content, and perform Signal Search summons for new Agents and items. One of the most important currencies in the game is Monochrome — a high‑value, real‑money currency players can buy to support their progression and pull on limited banners.

In Zenless Zone Zero, Monochrome refers to the premium currency that players cannot earn through normal gameplay. Instead, it must be purchased with real money through the in‑game store or official top‑up services.
Monochrome works much like premium currencies in other HoYoverse titles (such as Genesis Crystals in Genshin Impact): it can be directly converted into Polychrome, the currency primarily used for summons, restoring Battery Charge, and buying other in‑game items.
Here’s how that conversion works:
1 Monochrome = 1 Polychrome
That 1:1 exchange rate means Monochrome essentially buys you Polychrome directly — without waiting or grinding.
The primary and official way to buy Monochrome is through the Monochrome Market, which is part of the in‑game store. Players can choose from multiple purchase bundles that cost varying amounts of real money.
Typical tier options include:
Small bundles (e.g., ~60 Monochrome)
Medium packs (hundreds of Monochrome)
Large bundles (thousands of Monochrome)
Each purchase tier gives extra currency on the first time you buy it, a bonus called the initial top‑up bonus — meaning the wuthering waves lunite top up first purchase of a specific bundle gives you double Monochromes.
Buying Monochrome directly from the in‑game store ensures your purchase is safe, secure, and tied to your game account through official channels.
Another reliable way to get Monochrome is by purchasing Inter‑Knot Membership. It’s basically a time‑based subscription that rewards you each day for 30 days.
When you buy an Inter‑Knot Membership:
You receive 300 Monochrome instantly
You’ll also get daily Polychrome rewards for up to 30 days of claimed rewards
This option works well for players who want value over time rather than one‑off Monochrome purchases.
In certain regions, players also use trusted third‑party top‑up services to purchase Monochrome if they can’t use traditional payment methods inside the game (for example, if they don’t have international cards linked to their account). These services allow you to pay in local currency using methods like mobile wallets and local banking options.
These platforms usually require you to enter your ZENLESS Zone Zero UID and select a package. After you pay, the Monochrome will be credited to your account, often automatically.
⚠️ Always use reputable and official partners or well‑reviewed third‑party stores. Avoid unknown websites that ask for unnecessary account passwords.
Buying Monochrome isn’t required to enjoy the game — many players progress just fine via quests, missions, and natural Polychrome rewards. But Monochrome is attractive for several reasons:
1. Faster ProgressionMonochrome lets you convert directly to Polychrome, which you can then spend on Signal Search pulls — crucial for getting powerful Agents and W‑Engines without waiting to accumulate free currency.
Many players look forward to limited‑time banner events where certain Agents appear with better drop rates. Having extra Polychrome from Monochrome helps you take full advantage of these opportunities.
Some items in the in‑game shop are only purchasable with Monochrome. These might include cosmetic skins, timed offers, or special item packs that are otherwise unavailable.
For many players, buying Monochrome simply saves time. Rather than playing for weeks to stock up Polychrome, a Monochrome purchase gives instant access to currency for banners or limited‑time content.
Understand your goals: If you’re only interested in a specific character or Event, plan how much Polychrome you’ll realistically need before spending.
Use the first purchase bonus: The first top‑up bonus can nearly double the value of your money — always target that if you plan to spend.
Stay safe: Make purchases from official game menus or reputable top‑up partners to avoid scams.
Monochrome in Zenless Zone Zero is the premium currency that gives players the freedom to convert instantly into Polychrome, buy exclusive bundles, and maximize their experience in this urban fantasy action‑RPG. Whether you buy it through the in‑game Monochrome Market, get it as part of the Inter‑Knot Membership, or use trusted top‑up services, Monochrome can give you a competitive edge — as long as you spend wisely and sustainably.
