Get Customer Stablecoin Balances
Returns the live on-chain balances for a customer’s Smart Contract Wallet, read directly from Polygon PoS via eth_call — both balance_usdc and balance_usdt, since Rach supports the two stablecoins equally. Balances reflect settled on-chain state; there is no caching or internal ledger. Phone number must be URL-encoded (use %2B for +).
