how nohup works

nohup is a fair-launch token launchpad on uniswap v4. every coin is a real pool from its first transaction with full supply locked into a five-band staircase of concentrated liquidity.

overview

launching a coin creates a fixed-supply erc-20 and a native-eth uniswap v4 pool in one transaction. the entire supply is minted into a permanently locked staircase of concentrated-liquidity positions.

lifecycle

  1. launch — creator sets name, ticker, creator tax, and deepen lp tax (each 0–5%). optional dev buy in the same tx (max 0.1 eth, coin fee only — not the opening tax).
  2. staircase mint — the hook initializes the pool at start fdv and locks five liquidity bands covering the full supply.
  3. live trading — buys walk down the bands as market cap rises; sells walk back up. for 30 seconds after launch, swaps pay a decaying opening tax (80% → the coin's fee); extra above the normal split goes to locked deepen LP. then the chosen fee applies on every swap. deepen fees can be claimed into more locked full-range lp after a short cooldown.

token

each coin is a vanilla erc-20: fixed supply, no owner, no mint after init, no transfer tax, no transfer hooks. the full supply is minted to the hook at create and deposited into locked staircase lp.

fees

platform fee0.5% (fixed)
creator tax0% – 5% (chosen at launch, step 0.25%)
deepen lp tax0% – 5% (chosen at launch, step 0.25%)
total swap fee0.5% – 10.5% after the opening window
opening tax80% → coin fee over 30s (parabola; extra → deepen LP)
splitthree independent ledgers (platform / creator / deepen)

both taxes are immutable after launch. the 80% opening tax is protocol-fixed and not a creator setting.

creator rewards

creator and deepen taxes accrue in separate pull-payment ledgers on the hook:

creator tax → wallet

anyone can call claim; eth goes to the fee recipient (usually the deployer). claimable any time creator fees have accrued.

deepen lp tax → locked liquidity

claimDeepen swaps accrued eth for tokens and adds permanently locked full-range lp in the same pool. callable after a short cooldown following the last public swap.

platform fees accrue separately and are claimed to the protocol treasury the same way.

fair launch

  • trading opens the second after launch (`block.timestamp` past `launchTime`)
  • optional creator buy inside the launch transaction, capped at 0.1 ETH (~5% of supply). pays the coin's swap fee, not the opening tax
  • for 30 seconds from launch, public buys and sells pay a decaying opening tax from 80% down to the coin's fee. extra above the normal split is 100% locked deepen LP
  • creator and deepen taxes are immutable for the life of the coin
