| ## [2.0.0-alpha.13] - 2026-04-14 | ||
| ### Added | ||
| - **`ContractPreferredPaymentMethodType`** type (`card` | `bank_transfer`). | ||
| - **`paymentMethodRequired`** and **`preferredPaymentMethodType`** fields on `Contract`, `CreateContractParams`, and `PaymentSetupParams` — control whether a payment method must be set up for invoice checkout and which method is preferred. | ||
| - **`ContractSendParams`** type and optional `params` argument on `contracts.send(contractId, params?)` — allows passing `messageToSigners`, `deadline`, and `isKycRequired` when sending a contract for signing. | ||
