# kaia\_signTransactionAsFeePayer

Constructs a transaction with given parameters and signs the transaction with a fee payer's private key.

This method can be used either to generate a fee payer signature or to make a final raw transaction that is ready to submit to Klaytn network. In case you just want to extract the fee-payer signature, simply take the `feePayerSignatures` from the result. Note that the `raw` transaction is not final if the sender's signature is not attached (that is, `signatures` in `tx` is empty).

#### **Parameters**

The required parameters depend on the transaction type. Check the proper parameters in [Klaytn Docs](https://docs.klaytn.foundation/dapp/json-rpc/api-references/klay/transaction/transaction-type-support).

#### **Return Value**

| Type | Description                                            |
| ---- | ------------------------------------------------------ |
| raw  | Signed raw transaction                                 |
| tx   | Transaction object including the fee payer's signature |
