The door is open.
Until it isn't.

When a SOL lending vault lends out every loose coin, withdrawals stop and a line forms behind the door. OpenDoor turns your spot in that line into something you hold. Sell it for SOL right now, or keep it and the vault pays you when your turn comes.

Green at the slot means the vault is paying. When it goes dark, the line starts.

01 / the reserve

The SOL is in there.

A lending vault lends what you deposit. When everyone wants SOL at once, your balance is still yours and the loose SOL is gone.

02 / the line

Then you wait.

Every withdrawal that can't be paid joins a first-in, first-out line. It moves as borrowers repay.

03 / the door

Stand through the door.

Same line, same wait. Your ticket sits in a program account and the place sits on a ledger, so it can change hands.

04 / the exit

Sell it, or keep it.

Put a discount on your place. A buyer pays you SOL in one transaction and takes over the wait. No buyer, no loss.

05 / the token

$DOOR takes a cut.

Each place that sells pays a small door fee. Most of it goes back to $DOOR holders.

Set how many people are ahead of you and how fast the line moves, then drag the clock.

Nothing on the wall.

Places go on sale when a vault stops paying and a line forms. Each lit pane would be a place someone has priced. Buy one at a discount and the vault pays you in full when the line reaches it.

Places only come through the door. Tickets filed straight with a vault can't be bought.

$DOOR is the doorman.

Every place that sells through the door pays a 0.30% fee in SOL. That fee is split three ways, and holding $DOOR lowers what you pay and raises what you get back.

What is the line, exactly?

SOL lending reserves lend out deposits. When every loose SOL is lent, there is nothing to pay a withdrawal with, so the reserve files it as a ticket in a first-in, first-out queue. Tickets get paid as borrowers repay or liquidations land.

Why can't I just sell my ticket?

A ticket filed straight with the vault belongs to that wallet until it is paid. OpenDoor files the ticket from a program account made for one place, and keeps who holds that place on its own ledger. That is what lets the place change hands.

What does standing cost?

About 0.017 SOL of rent for a moment, for the place account, its token account and the ticket. Most of it comes back to the wallet that stood when the place closes, even if the place was sold. First-time standers can get it covered by the rent desk.

What if nobody buys my place?

Nothing is lost. You stay in line and the vault pays you in full when the line reaches you. The door fee only applies to a sale.

Where does $DOOR come in?

The 0.30% door fee on every sale is split between holders, buybacks and the rent desk. Holding more $DOOR lowers your own fee, down to zero at the Landlord tier.

Is this live?

Not yet. The program goes live with the token, and the CA is posted on X at @OpenDoorSol. Until then the calculators on this site run on numbers you type in.
