Every launch mints 1,000,000,000 tokens and opens a Uniswap v4 pool with 99% of them. The pair you pick is what the chart is quoted in, forever. Same form on Base, Robinhood Chain and Arc - chain is the first choice, and the differences are marked below.

​
What one signature does

1

Creates the token and opens the pool

At the market cap you chose, converted to a pool price from the pair’s live on-chain price.
2

Runs your dev buy

If you asked for one. Nobody gets in ahead of you.
3

Proves the launcher holds nothing

One token left in it and the whole transaction reverts. This is why liquidity can never be pulled.
On Robinhood Chain and Arc the form keeps to $500 - $10,000. The launcher contract on both chains accepts $250 - $15,000, and so does the agent API on Robinhood Chain. Some stock pairs refuse very low caps; the form warns and shows the exact opening price before you sign.

​
The form

basestonk.io/create has six tabs, in order: On a phone the tabs are a menu that reads Step N of M. Back and Continue move between them. A tab that does not apply to your launch is left out, and a tab with a problem carries a red dot. Your draft saves itself as you go. Above the launch button, a progress strip follows the launch through three stages: Preparing, Sign in wallet and Live. If a stage fails, it turns red and the reason is written under it. Not on the list? On Base you can nominate any token with a real market.

​
Simple or Advanced

They differ in one thing: who sets the tax and how it is divided. Simple starts with your whole half going to your fee address. One press on Recommended sends half of it to holders instead.

​
Presets

Advanced starts as Custom at 1% buy and 1% sell, with half your share going to holders. You set the rates and the split yourself. To start from a preset instead, choose Advanced under Launch type on the Info tab. A Presets menu appears on the line below it, showing Custom until you pick something. Open it and each preset lists its buy tax, sell tax and split. Picking one fills in the rates and the split. Change either afterwards and the menu reads Custom again. A preset only appears where the launch can do what it describes:
  • Where the $BSTONK basket is not offered (Robinhood Chain, Arc), Holder rewards gives that 20% to holders, so holders get 70%.
  • A B20 launch cannot pay holders, so Holder rewards, Balanced and Anti-dump are not offered for it.
  • Anti-dump needs different buy and sell rates, so it is hidden where a launcher cannot set them.

​
The wedges

An Advanced launch divides the creator’s share among these. Each runs inside the swap itself; none can be changed after launch by anyone.
On Base, the recommended split (Simple’s Recommended, and where Advanced starts) sends half of the holders’ share through the $BSTONK basket.

Protections

​
Your own buy

The amount is in the pair token, not dollars. Priced in AAPLc, 123 means 123 AAPLc. Read the symbol and the % of supply badge before signing.
Short of the pair token? The form swaps into it in the same flow; WETH pairs just wrap your ETH.

​
After launch

With supply SS and a pair worth PpairP_{\text{pair}} dollars, cap MM gives p0=M/(S⋅Ppair)p_0 = M / (S \cdot P_{\text{pair}}), stored by v4 as p0⋅296\sqrt{p_0} \cdot 2^{96}. The launcher opens a one-sided position from p0p_0 upward, so the first buyer moves the price first. PpairP_{\text{pair}} is read on-chain at execution - Chainlink, a routed feed, or a gate-verified route. A feed that cannot answer honestly refuses rather than guesses.
The launcher materialises an integer count of the pair’s smallest unit. Against a $150 stock, a $10,000 cap opens near $8,968, and under about $1,500 rounds to zero and reverts. The form shows the real opening figure.
St+1=St−V⋅wburn10,000⋅ptS_{t+1} = S_t - \dfrac{V \cdot w_{\text{burn}}}{10{,}000 \cdot p_t} - the same dollar burns more tokens at a lower price, which is when it matters.
