UnlistedFoundryHookV4
0x1ceb9eb9d7caef0f1fba73d6c6b0ae9475e3c8ccBlockscoutShared fee hook for all Foundry launchpad pools on Robinhood Chain. Takes ETH-denominated fees (1.00–1.25% scaled by pre-trade market cap), splits them between creator and protocol with configurable payout wallets, enforces anti-snipe restrictions during the launch window, blocks outside liquidity additions pre-graduation, and supports a graduation mechanism after which the hook fee drops to zero.
What it can do to your swap
- Can block swapsSwaps are gated (other): only some addresses, or only at some times, can trade through it.
- Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
- Can change the price you getBefore your swap runs, the hook can take or add tokens, so the amount you get is set by its code as well as the pool.
- Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
- Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
