MRPHook

EthereumRegistered

Collects a 3% tax on ETH-denominated exact-input swaps by intercepting both beforeSwap and afterSwap deltas, accumulating the tax as ERC-6909 native-ETH claims, and distributing the collected ETH to a token mine distributor. Also advances a rolling per-swap entropy seed using block randomness to support downstream randomized minting.
