# Transaction

### klay\_call <a href="#klay_call" id="klay_call"></a>

블록체인에 트랜잭션을 생성하지 않고 즉시 새 메시지 호출을 합니다. 결과 데이터를 반환하거나 또는 에러가 발생하면 JSON RPC의 에러 객체를 반환합니다.

**Parameters**

| gas      | QUANTITY     | (선택 사항) 트랜잭션 실행을 위해 설정한 가스양의 정숫값입니다. `klay_call`은 가스를 소비하지 않지만 트랜잭션 실행 중 일부에서 이 매개변수가 필요할 수 있습니다.                                                          |

**Return Value**

| Type | Description       |
| ---- | ----------------- |
| DATA | 실행된 컨트랙트의 리턴값입니다. |

컨트랙트를 배포했다면 [klay\_getTransactionReceipt](#klay_gettransactionreceipt)를 사용해 컨트랙트 주소를 확인하세요.

**Error**

문제가 발생할 경우 JSON RPC의 에러 객체를 반환합니다. 예를 들어, 어떤 메시지 호출이 `REVERT` opcode로 종료되면 "evm: execution reverted"라는 메시지의 에러 객체가 생성됩니다.

**Example**

```shell
// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "klay_call", "params": [{"from": "0x3f71029af4e252b25b9ab999f77182f0cd3bc085", "to": "0x87ac99835e67168d4f9a40580f8f5c33550ba88b", "gas": "0x100000", "gasPrice": "0x5d21dba00", "value": "0x0", "input": "0x8ada066e"}, "latest"], "id": 1}' https://public-en-baobab.klaytn.net

// Result

```

### klay\_estimateGas <a href="#klay_estimategas" id="klay_estimategas"></a>

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. 이때 발생한 트랜잭션은 블록체인에 추가되지 않습니다. Klaytn 가상머신의 메커니즘, 노드 성능 등의 다양한 원인에 의해 추정치가 실제 사용된 가스양보다 훨씬 클 수도 있습니다.

**Parameters**

| Name       | Type   | Description                                                                  |

| gas      | QUANTITY     | (선택 사항) 가스 추정을 위해 제공되는 가스 한도의 정숫값입니다. 가스 한도를 지정하지 않으면 Klaytn 노드는 지정된 가스 한도를 상한으로 설정합니다.                                                                    |

| input    | DATA         | (optional) Hash of the method signature and encoded parameters. It replaces `data` field, but 'data\` field is still supported for backward compatibility. |

**Return Value**

| -------- | ----------------------- |
| QUANTITY | The amount of gas used. |

  "result": "0x5208" // 21000
}
```

### klay\_estimateComputationCost <a href="#klay_estimatecomputationcost" id="klay_estimatecomputationcost"></a>

트랜잭션을 실행하는 데에 들 연산 비용의 추정치를 생성하여 반환합니다. Klaytn은 한 트랜잭션을 실행하는 데에 너무 많은 시간이 걸리지 않도록 하기 위해 현재 트랜잭션당 연산 비용을 `100000000`으로 제한합니다. 이때 발생한 트랜잭션은 [klay\_estimateGas](#klay_estimategas)와 마찬가지로 블록체인에 추가되지 않습니다.

**Parameters**

[klay\_call](#klay_call)의 매개변수들을 보면 모든 속성이 선택사항인 것을 볼 수 있습니다. 하지만 가스 한도를 지정하지 않으면, Klaytn 노드는 기본 가스 한도(uint64 / 2) 를 상한으로 설정합니다.

**Return Value**

| Type     | Description   |
| -------- | ------------- |
| QUANTITY | 사용된 연산 비용입니다. |

**Example**

```shell
// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_estimateComputationCost","params":[{"from":"0x73718c4980728857f3aa5148e9d1b471efa3a7dd", "to":"0x069942a3ca0dabf495dba872533134205764bc9c", "value":"0x0", "input":"0x2a31efc7000000000000000000000000000000000000000000000000000000000000271000000000000000000000000000000000000000000000000000000000000000420000000000000000000000000000000000000000000000000000000000003039"}, "latest"],"id":1}' https://public-en-baobab.klaytn.net

}
```

### klay\_getTransactionByBlockHashAndIndex <a href="#klay_gettransactionbyblockhashandindex" id="klay_gettransactionbyblockhashandindex"></a>

발신자 트랜잭션 해시로 조회한 트랜잭션의 정보를 반환합니다. This API works only on RPC call, not on JavaScript console. 이 API는 `--sendertxhashindexing`에 의해 인덱싱 기능이 활성화되어 있을 때만 올바른 결과를 반환합니다. [klay\_isSenderTxHashIndexingEnabled](https://archive-ko.docs.klaytn.foundation/content/dapp/json-rpc/api-references/config#klay_issendertxhashindexingenabled)를 호출하여 확인할 수 있습니다.

### klay\_getTransactionReceiptBySenderTxHash <a href="#klay_gettransactionreceiptbysendertxhash" id="klay_gettransactionreceiptbysendertxhash"></a>

SenderTxHash로 조회한 트랜잭션의 영수증을 반환합니다.

**NOTE**: The receipt is not available for pending transactions. Please note that this API returns correct result only if indexing feature is enabled by `--sendertxhashindexing`. This can be checked by call [klay\_isSenderTxHashIndexingEnabled](https://archive-ko.docs.klaytn.foundation/content/dapp/json-rpc/api-references/config#klay_issendertxhashindexingenabled).

**Parameters**

| Name | Type         | Description                                                                |
| ---- | ------------ | -------------------------------------------------------------------------- |
| Hash | 32-byte DATA | 트랜잭션 납부자(feePayer)에 의해 서명되기 이전의 트랜잭션의 해시입니다. (즉 senderTransactionHash입니다.) |

**Return Value**

### klay\_sendRawTransaction <a href="#klay_sendrawtransaction" id="klay_sendrawtransaction"></a>

Creates a new message call transaction or a contract creation for signed transactions.

**Parameters**

| Type | Description                  |
| ---- | ---------------------------- |
| DATA | The signed transaction data. |

**Return Value**

| Type         | Description                                                                    |
| ------------ | ------------------------------------------------------------------------------ |
| 32-byte DATA | The transaction hash or the zero hash if the transaction is not yet available. |

If you deployed a contract, use [klay\_getTransactionReceipt](#klay_gettransactionreceipt) to get the contract address.

**Example**

```shell
// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_sendRawTransaction","params":[{see above}],"id":1}' https://public-en-baobab.klaytn.net

**NOTE**: The address to sign with must be unlocked.

**Parameters**

필수적으로 있어야 하는 파라미터들은 트랜잭션 타입에 따라 다릅니다. [Working with Klaytn Transaction Types](https://archive-ko.docs.klaytn.foundation/content/dapp/json-rpc/api-references/klay/transaction/transaction-type-support)에서 적절한 파라미터를 확인하십시오.

**Return Value**

### klay\_sendTransactionAsFeePayer <a href="#klay_sendtransactionasfeepayer" id="klay_sendtransactionasfeepayer"></a>

주어진 파라미터로 트랜잭션을 구성한 다음, 트랜잭션 수수료 납부자의 개인키로 트랜잭션에 서명하고 트랜잭션을 Klaytn 네트워크에 전송합니다. 이 API는 오직 수수료 위임 트랜잭션(부분 수수료 위임 트랜잭션 포함)들만 지원합니다.

### klay\_signTransactionAsFeePayer <a href="#klay_signtransactionasfeepayer" id="klay_signtransactionasfeepayer"></a>

주어진 파라미터로 트랜잭션을 구성한 다음, 트랜잭션 수수료 납부자의 개인키로 트랜잭션에 서명합니다. 이 메서드는 트랜잭션 수수료 납부자 서명을 생성하거나, 최종적으로 Klaytn 네트워크에 전송할 준비를 마친 raw Transaction을 만들 때 사용할 수 있습니다. 수수료 납부자 서명을 추출하고 싶다면, 결과값에서 `feePayerSignatures`을 사용하십시오. 발신자 서명이 첨부되어 있지 않다면( `tx`에 있는 `signatures` 가 비어 있는 상태), `raw` 트랜잭션은 최종 상태가 아닙니다.

**NOTE**: The fee payer address to sign with must be unlocked.

**Parameters**

The required parameters depend on the transaction type. Check the proper parameters in [Working with Klaytn Transaction Types](https://archive-ko.docs.klaytn.foundation/content/dapp/json-rpc/api-references/klay/transaction/transaction-type-support).

**Return Value**

### txError: 트랜잭션 실행 실패에 대한 상세한 설명 <a href="#txerror-detailed-information-of-transaction-failures" id="txerror-detailed-information-of-transaction-failures"></a>

Klaytn은 트랜잭션 영수증의 `txError` 필드를 통해 트랜잭션 실행이 실패한 원인을 알려드립니다. 이 필드는 트랜잭션 실행이 실패한 경우에만 존재합니다. 스토리지와 네트워크 대역폭을 절약하기 위해 `txError`는 정숫값으로 표현됩니다. 아래 표는 `txError` 코드와 의미를 설명합니다.
