#![cfg_attr(docsrs, feature(doc_cfg))]

//! Solana chain support for the x402 payment protocol.
//!
//! This crate provides implementations of the x402 payment protocol for Solana blockchain
//! with the "exact" payment scheme based on SPL Token `transfer` instructions with
//! pre-signed authorization.
//!
//! # Features
//!
//! - **CAIP-2 Addressing**: Uses CAIP-2 chain IDs for chain identification
//! - **SPL Token Payments**: Token transfers using pre-signed transaction authorization
//! - **Compute Budget Management**: Automatic compute unit limit and price configuration
//! - **`WebSocket` Support**: Optional pubsub for faster transaction confirmation
//! - **Balance Verification**: On-chain balance checks before settlement
//!
//! # Architecture
//!
//! The crate is organized into several modules:
//!
//! - [`chain`] - Core Solana chain types, providers, and configuration
//! - [`exact`] - Solana "exact" payment scheme
//!
//! # Feature Flags
//!
//! - `server` - Server-side price tag generation
//! - `client` - Client-side payment signing
//! - `facilitator` - Facilitator-side payment verification and settlement
//! - `telemetry` - `OpenTelemetry` tracing support
//!
