in line,
on chain.

Block order, not trust
Position is determined when your transaction mines. No one can cut the line, no admin can reshuffle.
Transferable positions
Your slot is yours. Send it to any wallet that isn't already in the queue — OTC, gifting, whatever you need.
Creator controls
Open or close the queue at any time. Set a cap. The on-chain state is always the source of truth.
How it works
Four steps.
No middleman.
Every action is a transaction. Every position is a slot on the contract. Nothing happens off-chain.
01
Open
Any wallet calls createQueue() with a name, optional cap, and description.
02
Join
Wallets call join(). Your position equals the block your tx mines in — first in, lowest number.
03
Hold or Transfer
Call transfer(to) to move your slot to any other wallet. Vacate with leave().
04
Close
Creator calls setOpen(false). The final slot list is immutable on-chain forever.
The product
Exactly what it looks like
No dashboards, no wallets-of-spreadsheets. Just a list of positions, in order, on chain.
