Invent a unit.
Put it on the shelf.

Say what one of it is worth and place the entire supply on sale at that price. Coins can then be denominated in it exactly the way they are denominated in a currency — and it costs one transaction, because you put up no money of your own.

1

Name the unit

What it is, and how coins will refer to it.

Shown everywhere the unit appears.
How coins priced in it refer to it. First come, and permanent — nobody can take it off you and you cannot change it either.
2

Price it, once

This is the only price this unit will ever have. There is no keeper here and no instruction that could move it.

Understand what you are signing

Three things become permanent the moment you sign.

The code is first come. Once taken it is yours and it is fixed. If the code you want is already on the shelf, pick another — there is no transfer and no dispute process.
The price is placed once. Every listed currency has a keeper moving its wall whenever Pyth and Switchboard agree the real rate has drifted. A forged unit has neither. Whatever you type above is what this unit is worth forever, however far the world moves around it.
You never receive the money. The dollars buyers pay stay in the pool as the liquidity later sellers sell back into — exactly as nobody receives what the euro wall takes. What you get is a unit that exists and trades.

One transaction, plus network fee and rent. Nothing is reversible after signing.
