Understand the flow.

Parabolarc launches a token straight into Uniswap v4. One transaction deploys it, creates the pool, puts the entire supply into that pool, and locks the position. There is no bonding-curve phase and no migration afterwards. The pool has no hook, so anything that already trades v4 on the chain can trade it.

Every token opens near a $5,000 market cap, with a fixed supply of 1,000,000,000. The pool fee is chosen once, between 2% and 5%, and then frozen. Collected fees are not a creator tax stacked on a protocol tax. They are one fee, split five ways: a bid under the chart, a cash rebate for holders who are below entry, Labs, a $PARC buyback, and the creator.

On Arc the rebate is USDC. On Robinhood it is ETH. If you do not buy on this site, your entry is not recorded, and there is nothing to pay you.

From the first trade to a payout

1. The launch pool holds only the new token. The first buy is what puts USDC, ETH, or a stock into it.
2. Buys and sells pay the frozen pool fee into the locked position. The fee sits there until someone collects it.
3. A collection splits the quote. 30% is reserved for the floor, 30% for rebates, 15% for Labs, 15% for the $PARC buyback, and 10% for the creator. The token side of the fee is burned.
4. The floor share is placed as a one-tick bid under the spot. It only moves up, and it never goes below the opening price.
5. The rebate share pays wallets that bought here, held for 15 minutes, are below what they paid, and have never sold. Payments stop at break-even.

• I’m buyingThe pool starts with no bid. A sell only pays out quote that buyers have already put in.
• I’m launchingOne transaction deploys the token, opens the pool, and locks the supply. No launch fee.
• I’m below entryWho gets paid, how the shortfall is split, and when a round is actually claimable.

The rest of the guide is the opening price, the fee split, the floor, $PARC, and the contracts.
