/// The V2 SOR Router contract.
///
/// This router is generic over the network type, allowing it to work with both standard
/// Ethereum networks and OP-stack networks (Optimism, Base, Fraxtal).
///
/// # Type Parameters
///
/// - `N`: The network type (defaults to `Ethereum`). Use `op_alloy_network::Optimism` for OP-stack chains.
/// - `P`: The provider type.
///
/// # Example
///
/// ```rust,ignore
/// use odos_sdk::V2Router;
/// use alloy_network::Ethereum;
/// use alloy_provider::ProviderBuilder;
///
/// // Standard Ethereum usage
/// let provider = ProviderBuilder::new().connect_http("https://eth.llamarpc.com".parse()?);
/// let router: V2Router<Ethereum, _> = V2Router::new(address, provider);
///
/// // OP-stack usage
/// use op_alloy_network::Optimism;
/// let op_provider = ProviderBuilder::new()
///     .network::<Optimism>()
///     .connect_http("https://mainnet.base.org".parse()?);
/// let op_router: V2Router<Optimism, _> = V2Router::new(address, op_provider);
