Overview
Launch Trace is a token launchpad on Robinhood Chain (chain id 4663). A launch goes straight into a Uniswap v4 pool. There is no bonding curve, no graduation target and no migration. The token is tradable on the pool, on aggregators and on charts from the first block.
Launch flow
- You fill in name, ticker, image, X link and an optional website.
- You choose supply, starting market cap, allocation and fees within the limits below.
- Metadata is uploaded to Irys. The token stores the link as
metadataURI. - One transaction from the launcher creates the token, a dedicated fee hook and the v4 pool, then adds the remaining supply as single sided liquidity at your starting price.
- The LP NFT is held by the launcher contract. It has no function to withdraw it.
Because liquidity is single sided, the deployer wallet only needs ETH for gas. The deployer and the recipient are always two different wallets.
Fees
Three fees apply to every swap. All of them are set at launch and cannot be changed later.
| Fee | Range | Charged on | Paid to |
|---|---|---|---|
| Pool fee | 1–3% | Every swap | Recipient, via locked LP |
| Buy fee | 0.5–10% | Buys, in ETH | Recipient, via hook |
| Sell fee | 1–5% | Sells, in ETH | Recipient, via hook |
Hook fees are recorded as claims in the PoolManager and collected with collectFees(). Pool fees are collected from the locked position. Anyone can trigger a claim; the ETH always goes to the recipient.
Allocation
Between 10% and 30% of supply is sent to the recipient wallet at launch. The rest goes into the pool. Default supply is 1,000,000,000 tokens.
Liquidity lock
The Uniswap v4 position NFT is owned by the launcher contract for that token. The launcher can collect fees from it but has no path to decrease liquidity or transfer the NFT. That makes the lock permanent.
Metadata
Name, ticker, image, X and website are stored on Irys. Images are limited to 100 KB. Website is optional; image and X are required.

Each launch deploys its own launcher and fee hook. Their addresses are shown on the token page.
Risks
- Anyone can launch a token. A launch on Launch Trace is not an endorsement.
- Locked liquidity does not stop the price from falling. The recipient can sell their allocation.
- High buy or sell fees reduce what traders receive. Check the fees before every trade.
- Tokens with a similar name or ticker to a known project may be impersonations. Verify the contract address.
- Smart contracts can contain bugs. Only trade what you can afford to lose.
