How it works
One signature,
four markets
This page follows the money and the trust, step by step. If you only read one section, read "who you trust".
01
What you pay
The form quotes one number, read live from the registry: the pons launch fee, one fixed ETH slice for each of the three remote venues, and a fou4pad fee. Add an opening buy if you want one. A slice is the relayer's gas budget for that chain. It sits in the registry until the venue is live, then moves to the relayer. It never moves anywhere else.
pons launch fee
Read from the pons factory at the moment you sign and forwarded whole. fou4pad does not mark it up.
Three slices
One per remote venue, set by the operator to cover a create transaction on that chain plus the attest back on Robinhood Chain. Refundable, see 04.
fou4pad fee
Credited to the treasury on launch. Read protocolFee() on the registry for the current value. It is zero today.
Opening buy
Optional. Spent on the PONS curve in the same transaction, with the tokens sent to your wallet, not the registry. You are exempt from pons's opening snipe tax on this buy.
02
In your transaction
The registry deploys a small fee sink for your coin and calls the pons factory with your name, ticker, image and description. The sink is named as the creator fee recipient, the creator tax is set to 1%, and buybacks are off so the sink can always sweep without asking anyone. When the factory returns, the coin and its curve exist. The registry records them, escrows the three slices, and emits one event the relayer listens for. Nothing about this leg depends on any server.
03
On the other three chains
The relayer reads the metadata JSON your launch pinned, then creates the coin on each venue with the same name, ticker, image and description.
pump.funA create transaction signed by the relayer and by a mint key derived from your launch id, so the same launch always maps to the same mint. No dev buy. Creator fees accrue to the maker's Solana wallet.
FlapA Tax Token V3 through Flap's portal with a 1% buy and 1% sell tax whose beneficiary is the maker's BNB wallet. Metadata goes through Flap's own pinning API so their terminals index it.
ClankerA Clanker v4 token opening straight into a Uniswap v4 pool at 1.68 ETH of market cap, the same as the PONS phantom reserve. LP rewards go to the maker's Base wallet.
For each venue that went live the relayer writes the address into that launch's slot on the registry. That call releases the slice. A slot can be written once.
04
Who you trust
One key. The relayer can do exactly two things to your launch: put an address in an empty venue slot, or mark that slot failed. Marking it failed refunds your slice on the spot. It cannot touch the curve, the fee sink, your tokens, or anyone else's slices. If the relayer goes quiet, any slot still pending two hours after launch can be reclaimed by you with no signature from anyone else.
What is on chain
The registry, the pons leg, the fee sinks, the escrowed slices, the venue addresses once attested, and the refund rules. All readable on Robinhood Chain.
What is not
The relayer process itself, the maker process, and the maker's parameters (threshold and band). This page states them; the contract does not enforce them.
What pons can do
A pons community takeover can redirect a coin's creator fee recipient after its public three-day timelock. No fee sink can prevent that. It is a property of pons, not of fou4pad.
05
The maker
Every ten seconds it reads the four market caps. Nothing happens until one of them crosses $60,000. From then on, whenever the highest market is more than the band above the lowest, it sells on the highest and buys on the lowest for the same dollars.
Trade size is a quarter of the gap in the low market's cap, capped by a per-trade ceiling and by what the maker actually holds: tokens on the high side, cash on the low side. It cannot spend what it does not have and it never borrows. A leg that has graduated to a DEX is read for the arm but not traded.
06
Where the maker's money comes from
Each coin's fees, on each chain, are pointed at the maker. On PONS that is the 1% creator tax plus the creator's share of the base fee, collected through the coin's own sink, one sink per coin so nothing is commingled. On Flap it is the 1% tax. On pump.fun the creator fee. On Clanker the LP rewards. The team seeds the maker as well: fees alone would take a while to build inventory on four chains, and a maker with nothing to sell holds nothing level.
