Transaction

klay_call

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

callObject	Object	The transaction call object. See the next table for the object's properties.
blockNumberOrHash	QUANTITY \| TAG \| HASH	Integer or hexadecimal block number, or the string `"earliest"`, `"latest"` or `"pending"` as in the default block parameter, or block hash.

callObject

Object

The transaction call object. See the next table for the object's properties.

blockNumberOrHash

QUANTITY | TAG | HASH

Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter, or block hash.

NOTE: In versions earlier than Klaytn v1.7.0, only integer block number, the string "earliest" and "latest" are available.

klay_estimateGas

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.

klay_estimateComputationCost

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 100000000으로 제한합니다. 이때 발생한 트랜잭션은 klay_estimateGas와 마찬가지로 블록체인에 추가되지 않습니다.

Parameters

klay_call의 매개변수들을 보면 모든 속성이 선택사항인 것을 볼 수 있습니다. 하지만 가스 한도를 지정하지 않으면, Klaytn 노드는 기본 가스 한도(uint64 / 2) 를 상한으로 설정합니다.

klay_sendTransactionAsFeePayer

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.

참고: 서명하려는 트랜잭션 수수료 납부자의 주소는 잠금 해제되어 있어야 합니다.

Parameters

The required parameters depend on the transaction type. Check the proper parameters in Working with Klaytn Transaction Types.

Return Value

Type	Description
32-byte DATA	The transaction hash

Type

Description

32-byte DATA

The transaction hash

If you deployed a contract, use klay_getTransactionReceipt to get the contract address.

txError: 트랜잭션 실행 실패에 대한 상세한 설명

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