Atrium
A four-station production line drawn as a printed plate: an empty room is framed up, a ticker plate is slotted into its roof, keys are struck from a press, and a pool fills in a basin beneath the finished room, with a token travelling the single rule that joins all four. 1 2 3 4

Four steps, and then the room does the work.

Opening a room takes about a minute. What happens afterwards is the part that matters: every eligible trade on the room's keys buys the stock token the room chose, into a pool its holders claim from.

From empty to funded

The four steps.

Nothing here is reversible by the site. Each step writes to a contract or to a room record the contract reads.

Open

Name the room

Give it a name, a picture and a description. The picture is locked at creation because it is used for key mint metadata and cannot be rewritten later.

Choose

Pick its stock token

Choose one asset from the allowlist. 16 are live today. This choice is permanent for the life of the room, so the reward cannot be swapped out from under the holders.

Launch

Set the curve and keep keys

Set the base price and the step, and take your own creator keys at the same time. The creator is on the curve, not beside it.

Grow

Trades fund the pool

Eligible key trades buy the room's chosen token into a pool. Holders claim from that pool in the same stock the room picked.

What a trade actually does.

The four mechanics worth understanding before you mint a key, in the order you meet them.

Price

Price steps with supply

Each key minted raises the next key's price by the room's step. The curve is arithmetic and public, so the next price is something you can compute rather than something you are told.

Sell

Selling burns against the same curve

A sale burns the key and returns along the curve. Rooms may set a sell fee in basis points, which is a public property of the room, not a surprise at the point of sale.

Claim

Rewards are claimed, not airdropped

The pool accrues to the room. Holders call a claim rather than waiting for a distribution, so nothing depends on an operator remembering to run a script.

Metadata

Key metadata lives at a fixed URI

Each room's keys point at a metadata URI recorded when the room was created. It is why the room picture is immutable.

Creator alignment

The creator is on the curve.

A creator who can mint keys for free has no reason to care what a key is worth. A creator who bought theirs on the same curve as everyone else has exactly one.

  • Creator keys are taken at launch on the room's own curve.
  • The room's reward token cannot be changed after launch.
  • The room picture is immutable because key metadata points at it.
  • Selling is public: a creator leaving the curve is visible on chain like anyone else.

Read the contract terms before the marketing.

The documentation carries the curve, the fee behaviour, the safety controls and every deployed address.
