How MerchVault Works

Open vaults. Keep what you like. Ship the real merch when you are ready.

MerchVault is for music merch collectors who like the chase but still want the receipts. You buy stubs, open a themed vault, and land a real item in your collection. From there you can hold it, sell it back for stubs, or withdraw it for delivery. Odds are shown before every open. After the roll, the proof is there for you to check, and shipping has a real order trail.

Explanation

What MerchVault is, in plain English

Each vault is a published merch pool with visible odds. When you open one, the result lands in your collection with a proof record behind it. After that, you decide whether to hold it, sell it back for stubs, or ship it.

Vaults are item pools

A vault is a curated set of merch with published item values and probabilities. Some vaults are steadier. Some are built around bigger chase items. The page should make that clear before you open.

Stubs are closed-loop

Stubs are used to open vaults, pay shipping, and sell unwanted pulls back to the platform. They stay inside MerchVault.

Physical delivery is optional

A won item first lands in your collection. You only receive the physical item when you choose to withdraw it and meet the shipping minimum.

The Flow

How an opening turns into an item

Here is the path from choosing a vault to getting an item into your collection.

01

Choose a vault

Review the theme, price, item list, odds, and item values before spending stubs.

02

Open it

The fairness engine resolves the roll. The animation follows the recorded result.

03

Get the item

The item is added to your collection with quantity, value, and source context available to operations.

04

Decide

Keep it, sell it back for stubs, or add it to a withdrawal batch when you want the physical merch.

05

Track delivery

Withdrawals move through requested, sourcing, received, packing, shipped, delivered, hold, or canceled states.

Provably Fair

How the proof locks the roll

Every open uses a commit-and-reveal flow. The server commits to a hidden seed before the reveal, combines it with your client seed and nonce, then publishes the fields needed to recompute the result.

Commit before reveal

Before the open, the server seed stays hidden and its hash is committed. After the open, the seed can be revealed and checked against that hash.

Published inputs

The proof includes the server seed hash, revealed seed, client seed, nonce, drop table, and recorded item result.

Independent verification

After an open, use proof history to read the revealed seed, client seed, nonce, drop table, and awarded item. Hash the revealed seed, rerun the item selector, and compare it with the ledger result.

Proof checklist

The server seed hash exists before the item is revealed.

The revealed seed hashes back to the committed value.

The client seed and nonce match the open record.

The drop table used for verification matches the vault page.

The recomputed item ID matches the item awarded to the user.

Sourcing and Money

What happens after a user wins something

A pull creates an obligation the moment it lands. We track item value, held items, active withdrawals, sourcing status, supplier orders, and shipping status behind the scenes.

Some merch is stocked first

When we already have an item, fulfillment is simple: reserve it, pack it, and ship it once the user withdraws.

Some merch is sourced on win

For committed suppliers like Lambgoat Shop, Discogs, or future vendors, admins track vendor, order ID, order URL, cost, inbound tracking, and source status.

Liability is visible

Admin screens show held-by-users value and in-fulfillment value so we know how much merch may need to be sourced or shipped.

Fairness stays separate

Sourcing problems do not rewrite the roll. If an item cannot be fulfilled, support can place the order on hold, cancel it, or restore stubs without changing the proof.

Shipping

Withdrawals are treated like orders

Items stay in your collection until you choose to withdraw them. Once you submit a withdrawal, we show the order state, item list, source status when relevant, tracking information, and the next expected step.

Shipping minimum

Shipments require at least 5 items. The shipping fee is 500 stubs. This keeps small orders from turning into a fulfillment loss and lets users build a meaningful mail day before we pack it.

Requested

You submit a batch

You choose at least 5 items, confirm the address, and pay the 5 stub shipping fee.

Sourcing

We secure committed items

If an item must be ordered from a supplier, we track the source order separately from your outbound shipment.

Received

The item is in hand

Once sourced items arrive, the shipment can move into packing with the rest of the batch.

Shipped

Tracking is attached

Carrier and tracking number are added to the order monitor so you can follow the package.

Delivered

Order is complete

The shipment closes when delivery is confirmed or support resolves any exception.

Community

Reviews, Discord, and public receipts

Real shipment photos should come first. As orders go out, this page can grow into a receipts page with verified mail days, support visibility, community discussion, and clear updates when something is delayed.

Discord as the public room

Discord is where drop talk, support visibility, feedback, and community receipts can live once the invite is ready.

Verified mail days

After launch, this page should feature real shipment photos and withdrawal IDs from actual orders.

Transparent support

If sourcing is delayed, the order should say so. Accurate status builds more trust than a vague promise.

FAQ

Questions people ask before opening

Quick answers live here. The longer policy language lives in the Terms, Privacy Policy, and support pages.

Is the item decided by the animation?

The fairness engine decides the item. The animation shows the recorded result.

Can MerchVault change my item after the open?

The award record and proof stay separate from sourcing. If fulfillment has a problem, support handles the order path without rewriting the roll.

When do I receive the physical item?

Only after you withdraw it. Until then, the item sits in your collection and can be held or sold back for stubs.

Why is there a 5 item shipping minimum?

Small shipments can cost more to pack and send than they are worth. The minimum keeps fulfillment sustainable and keeps the shipping fee predictable.

What if a supplier order is slow?

The withdrawal can show sourcing or hold status while admins track the vendor order. If the item cannot be fulfilled, support can cancel or compensate according to policy.

Where should I check fairness?

Use your history page after an open. It shows the proof fields needed to verify the result inside the app.
