/**
 * Veil.cash Service — privacy pool integration for private transfers on Base.
 *
 * Uses @veil-cash/sdk for ZK proof generation and relayer submission.
 * Supports ETH and USDC privacy pools.
 *
 * SDK provides:
 *   - Keypair.fromSigner() — derive privacy keypair from Bankr sign API
 *   - deposit() — deposit into privacy pool (public → private)
 *   - withdraw() — withdraw from privacy pool (private → public)
 *   - transfer() — private-to-private transfer
 *   - balance() — check shielded balance
 *
 * Requires: @veil-cash/sdk npm package (optional dep, ~50KB).
