Description

button.fun launchpad hook — the single Uniswap v4 hook governing every bonding-curve memecoin pool on Robinhood Chain. Static LP fee is 0; the hook takes the entire trading fee on the quote side via before/after-swap deltas and routes it to a FeeRouter (protocol/creator/social/referrer split). Three phases per pool: launch-guard (anti-sniper fee decaying 90%->3% over ~5s), curve (flat 1% until graduation), graduated (flat 1% forever). Liquidity is managed by a PermanentLocker; graduated pools open to public LPs. Swaps require no custom hookData. Verified source on Blockscout.
