FEES
A share of every trade
Creators receive part of the trade fee on their token, in whatever asset the launch is priced in. It accrues to the launching address and can be withdrawn whenever.
PONSFAMILY
How launching on PonsFamily actually works.
PonsFamily is the token launchpad on Robinhood Chain, at pons.family. This page covers what happens between pressing launch and a token trading on Uniswap — the curve, the opening tax, the fees, and what is fixed forever.
A launch does not start as a pool
On most launchpads a creator has to seed liquidity before anyone can trade. pons does not work that way. The entire supply — one billion tokens on the standard configuration — is minted onto a bonding curve, and the curve itself is the counterparty. It will always trade with you in either direction, from the first second.
Price comes from how much of the supply has been bought. Buying raises it, selling lowers it, and nobody has to provide anything for the market to exist.
The opening price is not zero
The curve carries a phantom reserve: a virtual balance counted for pricing that nobody deposited and nobody can withdraw. On the standard settings it works out near 1.68 ETH, putting the opening price around 1.68 × 10⁻⁹ ETH per token.
The numbers, read off the contract
Every figure below comes from the deployed factory rather than from documentation. Where the two disagree, the chain is the one that settles trades.

Opening tax window — the docs say five
The 99% opening tax
A bot watching for new curves could buy the opening before anyone knows the launch exists, then sell into the people who arrive a minute later. pons prices that behaviour out instead of trying to block it: buying is taxed at 99% the moment a launch opens, and the rate decays exponentially to nothing.
The decay is steepest at the start. Roughly a quarter of a purchase is still taken one second in, around three percent at two seconds, and nothing by the end of the window. Selling is never taxed by it, at any point.
Whatever the tax collects is not burned. It joins the launch's trading fee and is distributed the same way, so value a would-be sniper gives up flows back into the launch.
Team wallets are exempt
A creator names addresses at creation that the tax does not apply to — up to 32 of them. The protocol documents this as being for a team bundling its opening buys across several wallets. The list is fixed the moment the token is created and cannot be extended afterwards.
What graduation means
When the curve has collected 4.2 ETH it closes, and everything it holds seeds a Uniswap v4 pool. The position is minted full-range and transferred straight to a locker where it stays permanently.
This is worth stating precisely. A rug pull almost always works by the creator withdrawing liquidity. On a graduated pons token that is not a promise to behave — the function to withdraw does not exist, for anyone, including the protocol.
Because the reserved share is fixed at creation, every launch on identical settings arrives at a pool of identical size at identical price, whether the curve was bought out by one order or by hundreds.
What a creator gets
TERMS
A tax you set once
An optional creator tax of up to 10%, fixed at creation. It cannot be raised on holders later, which is the point of fixing it.
BUYBACKS
Fees that buy back
A creator can route part of the fee into buying the token back. Bought tokens are locked rather than returned to circulation.
Worth knowing before you launch
- Name, symbol, supply and terms are fixed at creation and cannot be changed
- The exemption list is fixed too — decide your team wallets first
- pons v2 is unaudited by its own account: three reviews are open, none closed
- Robinhood Chain orders transactions by arrival, so paying more gas buys nothing
Where Arrow fits
Arrow creates the token on pons and takes the opening with 5 to 32 wallets named on that exemption list — one screen instead of a script. Everything on this page is true whether you use it or not.

Common questions
Is PonsFamily the same as pons?
Yes. pons.family is the site; the contracts and documentation call the protocol pons. People search for both, and they are one thing.
What does it cost?
0.0005 ETH to launch, plus gas measured in fractions of a cent. Trades on the curve pay 1%. A creator can add a tax of up to 10%, fixed at creation.
Can liquidity be pulled after graduation?
No. The pool position is minted to a locker and there is no withdrawal function — not for the creator, not for the protocol. That is a property of the contract rather than a promise.
Do I need a bundler to launch?
No. Anyone can launch directly on pons.family. A bundler matters only if you want an opening position across several wallets inside the tax window, which is fiddly to do by hand in three seconds.
