Launch pools and pooled buying

LaunchPools creates a new ERC-20 together with its own ZKDepth pool in one transaction, so no one can hold or trade the token before its market exists. These are contracts anyone can call; the app's own flow is the Launchpad. A launch vault lets a group buy at launch for one price, and any Pons token can get a ZKDepth pool next to it.

What one launch does

1. 1
   Deploy the token

   A plain 18-decimal ERC-20 whose whole supply is minted once.
2. 2
   Create and seed the pool

   A DAMM pool of native ETH against the token, tick spacing 60, opened at your start price. The seed holds only the token and sells it to buyers at every higher price.
3. 3
   Buy, if you sent ETH

   The ETH buys the token as the pool's first swap, so nobody can trade ahead of it.
4. 4
   Hand out the rest

   Tokens bought and any ETH paid back go to you. The supply the pool did not take goes to the creator you named.

The token's address is unknown until the launch lands, so nobody can create the pool first. A launch cannot go through while the venue is paused.

The launch buy and the launch fees

A buy inside the launch transaction pays the full start fee. But the launch position is then the pool's only liquidity, so LaunchPools pays the LP part back to the buyer. Only the protocol share stays charged, 20 % of the fee at deploy: 500 bps of the buy with the form's defaults.

LaunchPools holds the seeded position and has no function that removes it. collectFees(id) is open to anyone and pays the LP fees to the launch's fee recipient, even while the venue is paused. setFeeRecipient(id, to) lets the current recipient, and only them, hand the fees on.

Pooled buying with a launch vault

Everyone's ETH goes into one first buy, so every depositor pays the same average price.

1. 1
   Open

   LaunchVault.open(p, depositEnd) stores the launch parameters for good. depositEnd must be at most 7 days away, and the form defaults to 24 h.
2. 2
   Deposit

   Until depositEnd anyone can deposit ETH and withdraw any part of their own deposit.
3. 3
   Launch

   From depositEnd until 3 days after, anyone can call launch(id), which spends the vault's whole balance as the first buy.
4. 4
   Claim, or refund

   After a launch, each depositor claims a share of the tokens and of the ETH paid back. If nobody launched in time, each refunds the whole deposit.

The unseeded supply and the position's fees go to the creator the opener named. A depositor's one cost is the protocol share of the start fee. The buy has no price limit, so the more ETH the vault holds, the higher up the curve it buys.

Pons tokens

Pons is a third-party launchpad on Robinhood Chain, and its tokens are at /launch/pons. A Pons token trades on a bonding curve until it graduates, and then in a Uniswap v4 pool. The Router takes either as a hop, under your minimum output and deadline.

Open a ZKDepth pool calls DammHook.createPool for the token against its pair token, at a start price prefilled from the live Pons price. Defaults: 100 bps base fee, 2,000 bps anti-snipe fee falling over 600 s, tick spacing 200. The pool starts empty, and only one per tick spacing can exist.

Curve trades pay the Pons curve fee and the creator tax, and buys also pay a snipe tax while one applies. ZKDepth does not list or vet tokens. The bonding-curve launchpad is a separate product, see Launch.
