How to launch a token on PonsFamily, start to finish
Launching on PonsFamily costs 0.0005 ETH and takes about a minute. The part worth slowing down for is not the launching — it is the three decisions that are written permanently into the contract at that moment and cannot be revisited.
What you need before you start
A wallet with ETH on Robinhood Chain, chain id 4663. This matters more than it sounds: the same address on Ethereum or Arbitrum holds a separate balance, and ETH sent to the wrong network is not lost but is not reachable from the launch either.
Beyond that, very little. There is no liquidity to provide, because the bonding curve is the counterparty from the first second. There is no pool to create and no pair to fund.
- ETH on Robinhood Chain for the launch fee and the opening buy
- A name, a symbol and a logo
- The list of wallets you want exempt from the opening tax, decided in advance
The three things that are permanent
Everything else about a launch can be worked around. These cannot.
The first is the token itself: name, symbol, supply and decimals are set at creation and there is no function to change them. The second is the creator tax, up to 10%, fixed at the same moment — it cannot be raised on holders later, which is the point of fixing it, but it also cannot be lowered if you set it too high.
The third is the exemption list. Up to 32 addresses that the opening tax does not apply to, written when the token is created and closed immediately. A wallet you forget pays the full tax for the rest of the window, and there is no way to add it afterwards.
What it costs
The launch fee is 0.0005 ETH. Gas on Robinhood Chain runs to a fraction of a cent, so for practical purposes the fee is the cost. Trades on the curve pay 1%, split between the protocol and the creator.
The larger cost is not a fee at all: it is the opening buy. Whatever position you want in your own token has to be bought at the same prices everyone else pays, minus the tax you are exempt from.
The opening window
The moment a token is created, buying is taxed at 99%, and the rate decays to nothing within three seconds. This is why the exemption list exists and why it is decided in advance rather than during.
Your own dev buy is not affected either way: it executes inside the launch transaction itself, so nothing can trade before it. Wallets buying separately need to be on the list and need to arrive while the window is still open.
After the launch
The curve trades until it has collected 4.2 ETH, then graduates: its reserves seed a Uniswap v4 pool and the position is locked permanently. Nothing about your holdings changes at that point — same token address, same balances, same wallets.
Creator fees accrue to the launching address throughout, in the currency the launch is priced in, and are withdrawn from an escrow contract rather than arriving automatically.

Check a launch yourself
The pons bundle checker reads any PonsFamily launch and reports how many wallets took the opening free of the launch tax, and whether they still hold it. Free, no account.

The exemption list: 32 addresses, fixed at creation
pons lets a creator name up to 32 addresses that the opening tax does not apply to. The list is fixed when the token is created and can never be extended.
