NummusPad is a launchpad on Arc where every coin trades against a world currency instead of a dollar. A coin born in yen is priced in yen, raises yen, and pays its creator in yen.

You still pay with USDC. The desk swaps it into the currency on the way in and back on the way out, so the currency is a fact about the coin, not a chore for the trader.

Each currency is its own token on Arc, issued by the desk, one to one with the real thing at the live rate.

The desk mints a currency for USDC and burns it for USDC, at a rate a keeper posts from Pyth, the ECB and two more sources. It keeps a USDC reserve per currency that covers everything in circulation.

When the rate is stale the desk closes, launches pause, and existing coins keep trading in their currency.

Every coin starts on a bonding curve with the same shape as pump.fun, scaled to its currency so the dollar numbers line up across all of them.

When the curve fills, the 206.9M kept tokens and everything raised go into a Uniswap v4 pool against the currency. The position is held by a contract that cannot withdraw it, so the liquidity stays for good.

A hook on the pool sets the fee by market cap tier and keeps sending the creator their share of every trade.

Earnings accrue in the coin's currency on the curve and in the pool. Claim them from the coin's page whenever you like. The fee recipient can be changed by the creator.
