Doorway

EthereumRegistered

Congestion-fee hook for a WBTC/INDOOR pool that charges a dynamic sell fee (1–25%) modeled on EIP-1559: the rate adjusts each block based on satoshis sold, and fees are routed directly to a fixed recipient ("the Room") via BeforeSwapDelta and afterSwapReturnsDelta. Buys are always free.

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.
