Indoor prices its exit the way Ethereum prices a block. Rush the door and it costs you satoshis. Those satoshis stay in the room, behind everyone who did not rush.

Two doors

Both are always open

Nothing is ever locked, paused, queued or vested. You choose which door, and the choice is the whole mechanism.

The market door

Sell into the pool

Instant, at whatever the market will pay, and it pays the congestion fee. The more satoshis leave through this door in one block, the more the next one costs.

The back door

Leave the room

Burn your INDOOR and take exactly your share of the satoshis in the room. No queue, no congestion, no haircut, and no market to move. It always pays the same price.

Because the back door pays a known price, the fast door can never trade far below it for long: below the floor, redeeming is free money and the discount closes itself. The floor is not a promise we make. It is an arbitrage.

The doorway

The fee is produced, not chosen

There is no admin behind this number. Each block it moves by how far that block’s selling missed its target, damped by 8, exactly as an Ethereum basefee does.

Tidying up

The room buys its own token back when the market is wrong

While the pool quotes INDOOR below what the room would redeem it for, anyone may call tidy(). It spends satoshis from the room to buy INDOOR out of the pool and burns every token it gets.

Buying below book value and destroying what you bought raises book value per token. Always, arithmetically, for everybody who stayed. The caller keeps 0.50% for the gas and the trouble.

The one claim

Satoshis per INDOOR never fall. Not on a sell, not on an exit, not on a tidy, not in any order you put them in.

That is the whole protocol, and it is tested as a single invariant rather than asserted as a slogan. What it does not claim: the market price. The room tells you what you can redeem, never what somebody will pay.
