Questions
Is there a bonding curve?
No. Coins go straight into a Uniswap v4 pool at the starting market cap you choose. What you see on the chart is the real pool price from the first trade.
Can the liquidity be pulled?
No. The position sits directly in the Uniswap v4 PoolManager under the coin's own Shell contract, and Shell has no code path that removes liquidity. There is no LP NFT to sell or transfer. Fees can be poured out, liquidity cannot.
Why two wallets?
The deployer wallet only pays gas and deploys. The recipient wallet gets the allocation and every fee. Keep them separate so a throwaway deployer never touches your earnings.
Do contracts get shared between coins?
No. Every hatch deploys a fresh Hatch, Shell and token. Shell is the pool hook, the liquidity owner and the fee vault for that one coin only.
What does Yolkbop take?
Nothing. There is no platform fee on deploys or trades.
Risks, plainly
Anyone can hatch a coin, including people copying names of real projects. A locked LP stops a liquidity pull, it does not stop the recipient from selling their allocation.
Fees up to 10% on buys make small trades expensive. Check the settings panel on every coin page before you buy.
Nothing on Yolkbop is investment advice. Only trade what you can afford to lose.
