- Refactor `get_wallet()` to return `ton_balance` and `usdt_balance` in `WalletInfo`. - Update transaction processing to validate balances for both TON and USDT payment methods. - Introduce `parse_required_payment_amount` utility to extract payment amounts from responses. - Modify tests to cover new balance checks and payment method handling. - Upgrade GitHub Actions artifact upload action to v7. - Enhance documentation and examples to reflect changes in wallet balance handling.

Fragment transaction payloads are BOC-serialised TVM cells. This function
