EIP-1559 Rules: Each block has a target of 15M gas. If a block is >50% full, base fee increases by up to 12.5%. If <50% full, it decreases. The base fee is burned (removed from supply). Miners only keep the priority fee (tip). Your max fee caps total spend: effective fee = min(base_fee + priority_fee, max_fee).
