A safe is an NFT token on BNB Smart Chain. While it sits on your internal wallet (staking), its AM weight works for your share of the network. Everything else about a safe — class, level, traits, mints — affects its weight or how cheaply you can grow it.
Safe parameters
| Parameter | Meaning | Affects |
|---|---|---|
| Weight (AM) | The main parameter | Share of AMA2 rewards |
| Class | Regular, Silver or Gold — random | Weight multiplier, level gain, level cap, forge luck |
| Quality | Weight multiplier rolled within the class range | Gain of every level |
| Level | Bought for AMA2 | +8% × quality to weight, mint slots |
| Start weight, “+xx%” | Weight at purchase or mint; next to the weight — how much it grew since | Shows what levels, keys and growth added |
| Capacity | The maximum weight of the safe: base weight × class multiplier | The weight never grows above it; it can be expanded |
| Growth | % of the base weight the safe gains every day | Free weight gain until the safe is full |
| Rarity gene | P.p. added to the top class chance in the forge | Chance to forge Gold |
| Mint (resource) | How many mints the safe can join, and how many it has done | Forge freshness: −15% luck for each mint |
Safe traits
Every paid safe is born with four traits. The lighter a safe is born within its range, the better they are — a light safe is a promising one: it grows longer and faster and works better in the forge.
| Trait | Regular | Silver | Gold |
|---|---|---|---|
| Capacity, × base weight | ×4–8 | ×6–12 | ×10–20 |
| Growth, % of base weight a day | 0.02–0.06 | 0.04–0.08 | 0.06–0.12 |
| Rarity gene, p.p. | 0.5–4 | 2–6 | 4–10 |
| Mint resource | 2–4 | 3–5 | 4–6 |
Base weight is the start weight of the safe (when bought, with class, sale, first purchase bonus and coupon, or when minted). For safes bought before traits existed, the base weight is their weight when they got their traits. A forged safe inherits 20% of its parents capacity and growth.
Capacity
A safe never weighs more than its capacity: levels, keys, daily growth and the collection bonus stop there (weight already gained is never taken away). The bar under the weight on the card shows how full the safe is. A full safe takes no level.
Expansion — “Expand capacity” in the ☰ menu of a safe: +10% of the base capacity per step, up to 10 steps. The price is 100% of the showcase price of the added AM (at least 400 AMA2). Expansions stay with the safe when it is sold.
Growth
Every day a safe gains a percent of its base weight — linearly, until it is full. Every 5 account levels add +0.002% a day. Details and the table are in AM weight. A growth key adds +0.01% a day forever (up to the class maximum +0.05%), see Modifiers.
Rarity gene
In the forge the parents genes add to the chance of the top class: the five strongest in full, the rest by half, with freshness; plus the account level (+0.1 p.p. a level, up to 2). At most 40 p.p. in total, the top class at most 85%. Every 5 safe levels add +0.25 p.p. to its gene.
Mint resource
How many mints a safe can join. The card shows “Mint: 2 of 3 free”: used of available. Safe levels 5 and 10 open one more slot each.
Series collections
Different designs (pictures) of one series you hold give every safe of that series extra weight in the distribution — a share of its base weight: 3 designs +2%, 5 +4%, 10 +7%. Example: a safe with a base weight of 50 AM counts 3.5 AM heavier in the distribution at +7%, however many levels it has. Never above the safe capacity; the safe own weight and its “+xx%” do not change. The card shows the series bonus next to its name, e.g. “Space +7%”.
All traits, expansions and growth from keys belong to the safe and go to the buyer when it is sold; account level bonuses follow the owner.
Safe classes
The class is rolled when a safe is bought from the showcase or forged. Each class has its own chance (a share among all active paid classes) and weight multiplier range. The account level raises the chance of advanced classes — up to +13 pp.
| Class | Weight multiplier | Level cap | Feature |
|---|---|---|---|
| Regular | ×1 | 10 | The backbone of the network, cheap forge material |
| Silver | ×1.1–1.3 | 15 | Levels give more weight, "alloy" in the forge |
| Gold | ×2–3 | 20 | Each level is 2–3 times stronger, highest cap |
Level: formula and price
Levels are bought with the “Level up” button on the safe card or on its page. The gain depends on the current weight and quality, and the price on the level number:
Put simply: a safe of the epoch start weight pays the table — 100 AMA2 for the first level, each next one 1.5 times dearer. A heavier safe pays more, but not in proportion to its weight: four times heavier — twice as dear; a lighter one pays less, but at least 30 AMA2. A level cut by the capacity costs only the part of the price that matches the part of the gain it adds. High levels are a goal to save for: they bring weight, mint slots at levels 5 and 10 and a stronger rarity gene.
| Safe | Lvl 1 | Lvl 5 | Lvl 10 | Weight at lvl 10 | Total 1–10 | Avg per 1 AM |
|---|---|---|---|---|---|---|
| Regular 35 AM | 100 +2.8 | 590 +3.8 | 5,434 +5.6 | 75.6 | 14 977 | 369.26 |
| Regular 140 AM | 200 +11.2 | 1,180 +15.2 | 10,869 +22.4 | 302.3 | 29 960 | 184.64 |
| Gold 35 AM | 100 +7.0 | 728 +14.5 | 8,731 +36.1 | 216.7 | 22 151 | 121.90 |
Prices in AMA2 for epoch Ziton; next to them — the weight gain of the level in AM. The exact price of the next level is shown in the safe menu.
Level cap and mint slots
- Cap: Regular — 10, Silver — 15, Gold — 20. Safes upgraded beyond it before the cap was introduced keep their levels.
- Mint slots: a safe can join the forge as many times as its mint resource allows; levels 5 and 10 open one more slot each.
- Capacity: a level never lifts the weight above the capacity; a full safe has to be expanded first.
- Demo safes can't be upgraded.
Safe actions
- Upgrade — raises level and weight for AMA2 (☰ menu on the safe card).
- Modify — apply a modifier key.
- Forge — take part in minting a new safe; the source safe stays yours.
- Sell and withdraw — from the Wallet page. A safe withdrawn to an external wallet no longer counts towards your weight.
