**address** | **String** | Indicates the wallet address to be used as the source of funds. - For UTXO-based chains: both `address` and `included_utxos` are optional. If both `address` and `included_utxos` are provided, the UTXOs must belong to the specified address. If neither `address` nor `included_utxos` is provided, the system will select UTXOs from the wallet associated with `wallet_id`. - For account-based chains: You need to provide `address` otherwise the token transfer will fail. However, when estimating fees for a transfer, `address` is not required.  For detailed rules on `address` and `included_utxos` in both regular and RBF transactions, see [Address and included_utxos usage](https://www.cobo.com/developers/v2/guides/transactions/sources-and-destinations#address-and-included-utxos-usage).  | [optional]
