3//! Solana chain support for the x402 payment protocol.
4//!
5//! This crate provides implementations of the x402 payment protocol for Solana blockchain
6//! with the "exact" payment scheme based on SPL Token `transfer` instructions with
7//! pre-signed authorization.

10//!
11//! - **CAIP-2 Addressing**: Uses CAIP-2 chain IDs for chain identification
12//! - **SPL Token Payments**: Token transfers using pre-signed transaction authorization
13//! - **Compute Budget Management**: Automatic compute unit limit and price configuration
14//! - **`WebSocket` Support**: Optional pubsub for faster transaction confirmation
15//! - **Balance Verification**: On-chain balance checks before settlement
