 * EVM charge method for MPP — shared schema used by both server and client.
 *
 * Supports ERC-20 token transfers on any EVM chain (SKALE, Base, Polygon, etc.).
 * The client sends a tx hash after broadcasting, and the server verifies the
 * Transfer event on-chain.
 *
 * SKALE chains are gas-free, making them ideal for MPP micropayments.
