How We Source, Review and Publish Our Data

Who maintains this site

Brainrot Vault is an independent fan project, not a company and not a game studio. Active Steal a Brainrot players maintain the codes list, the item database, the tier list and the trade calculator. There is no sponsored placement anywhere on the site: no item is ranked higher, and no code is listed longer, because someone paid for it.

Where our codes come from

Codes reach us from three kinds of source, and we treat them differently. First, official channels — the game description on the platform, and announcements published by the developers themselves. Second, established community trackers and Discord servers with a record of getting it right. Third, individual player reports sent through our contact form. A code from an official channel is treated as confirmed. A code from anywhere else is treated as a claim we have not confirmed, and it is labelled that way on the page.

What the trust labels mean

Every code on the site carries one of these labels, and the label is the honest limit of what we know:

• Official — the code was published by the game developers through a channel we can point to. This is the strongest claim we make about a code.
• Pending Check — the code has been reported to us but we have not confirmed it ourselves. It may work. It may already be dead. We still show it, because a code you cannot see is a code you cannot try, and a failed redemption costs you nothing.
• Expired — we have reason to believe the code no longer works, such as a stated end date or a developer announcement. Absence of confirmation is not evidence of expiry, so we do not move a code here just because it has gone quiet.

Why a listed code can still fail

Codes fail for reasons that are invisible from outside the game. Most are capped at a fixed number of redemptions and die silently once the cap is hit. Many are one-per-account, so a code that works for a friend will bounce for you if you already used it. Some are tied to an event that has ended. And codes are case-sensitive and space-sensitive — a trailing space copied from a screenshot is enough to break one. If a code fails for you, telling us through the contact page helps us date it correctly.

How item trade values are sourced

A trade value on this site is a reading of what the trading community actually gives up for an item — not a price set by the game. We read it from active trading channels and cross-reference more than one source before publishing. Values are stored as a single number because that is what a calculator needs, but read each one as the middle of a range that real trades scatter around.

What we will not do to a trade value

We do not derive a trade value from an item's in-game purchase cost or its income per second. Those are real numbers published by the game, and we show them where we have them, but they do not predict trade value — across the items we track, the ratio between cost and trade value varies enormously. Filling an empty value with a figure computed from cost would look like data and behave like a guess, so we leave it empty instead.

Why some items show no value at all

When a new brainrot is released we can usually confirm its rarity, its in-game cost and its income per second on day one. Its trade value does not meaningfully exist yet, because the trading community has not converged on one. Those items are published with their confirmed data and a blank trade value, shown as a dash. They are not broken pages and they are not oversights — a blank is the accurate answer until enough real trades exist to replace it.

Why values change

An item's value moves when its supply moves, or when demand does. A brainrot that was hard to obtain becomes common when it returns in an event, and its value falls. A limited item that can no longer be obtained grows scarcer every week, and its value climbs. Updates that change income rates, add fusions, or introduce a stronger item at the same rarity reprice everything around them. We re-check values on a rolling basis and update them when the shift is large enough to change a trade decision.

How the tier list is decided

Tiers are bands of trade value, adjusted for how readily an item actually moves. S is the top band, D the entry band. Two items with similar raw values can land in different tiers if one of them trades easily and the other sits. Because tiers are derived from value, an item with no confirmed value has no tier either — you will see both fields blank on the same page, which is consistent rather than missing.

What the trade calculator does and does not do

The calculator adds up the values on each side of a trade and reports the gap, treating a difference of roughly ten percent or less as fair. What it cannot see is the part of a trade that is not arithmetic: how badly the other player wants your item, whether either item is about to be re-released, or whether you are trading for something you simply enjoy owning. Treat the verdict as one input, not a ruling.

Corrections

If a number here is wrong, we would rather hear it than defend it. Report an expired code, a stale value or any other error through the contact page, and include what you saw and where. Code reports are the fastest to action. Value corrections take longer, because we look for corroboration before moving a published number — one report of a bad trade is not the same as a shift in the market.

Independence and affiliation
