//! CCTP contract bindings
//!
//! This module contains Alloy-generated contract bindings for interacting with
//! Circle's Cross-Chain Transfer Protocol smart contracts.
//!
//! - v1: Original CCTP contracts (7 chain families)
//! - v2: Enhanced contracts with Fast Transfer, hooks, and 11 v2-capable
//!   chain families (the v1 set plus Linea, Sonic, Sei, HyperEVM). The
//!   protocol parser handles all 21 announced CCTP v2 domain IDs
//!   independently of bridge SDK support.
//!
//! ## Public API
//!
//! Contract wrappers provide type-safe, instrumented interfaces to CCTP contracts:
//!
//! - v1: [`TokenMessengerContract`](token_messenger::TokenMessengerContract), [`MessageTransmitterContract`](message_transmitter::MessageTransmitterContract)
//! - v2: [`TokenMessengerV2Contract`](v2::TokenMessengerV2Contract), [`MessageTransmitterV2Contract`](v2::MessageTransmitterV2Contract)
//! - ERC20: [`Erc20Contract`](erc20::Erc20Contract) for approval and allowance operations
