UniPerps

EthereumRegistered

A gamified ERC20 token hook that applies a 10% ETH tax on both buys and sells via BeforeSwapDelta/AfterSwapDelta, forwarding taxes to a fixed treasury. Sellers become a "corpse" for 100 blocks; the next buyer within that window "raises" the corpse, otherwise it expires.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.
