Smart Contract 배포 및 조회

앞서 등록 및 생성한 정보를 활용하여 Smart Contract를 블록체인에 배포합니다.

사전 조건

1. ChainZ API Service를 사용하기 위한 인증이 되어 있어야 합니다. 자세한 사항은 Getting Started > 인증 정보 생성 및 Getting Started > 액세스 토큰 발급 항목을 참고하시기 바랍니다.

2. 발급된 액세스 토큰이 유효 기간 내에 있어야 합니다.

3. Contract Artifact(ABI, Bytecode 및 추가 정보)가 ChainZ API Service에 등록되어 있어야 합니다. 자세한 사항은 'Contract Artifact 정보 등록 및 조회' 항목을 참고하시기 바립니다.

4. Account API를 통해 생성한 Account의 Address를 알고 있어야 합니다. 자세한 사항은 'Account 생성 및 조회' 항목을 참고하시기 바랍니다.

Smart Contract 배포 및 조회

Smart Contract 배포

1. API 정보

Transaction API의 callContractFunction을 사용합니다(참고 링크).

2. 입력 정보

  • 액세스 토큰 & API 키

  • ChainID - Blockchain 식별 정보

  • clientReqId - Request 의 사업자 고유 식별 정보

  • params - From Account의 Address, Contract ID, 초기값 매개변수

3. Smart Contract 배포 예시

Transaction API를 사용하여 Transaction을 전송합니다.

# Transaction API(Smart Contract 배포) 사용 예시 - Request
curl -X POST "https://tx-api.chainz.biz/api/v1/transactions/contract-deployment" \
    -H  "accept: application/json" \
    -H  "x-api-key: {API 키}" \
    -H  "Authorization: Bearer {액세스 토큰}" \

            "clientReqId": "dc397f5d-6eb6-49e2-a4b4-b603b29c4729",

clientReqId(Client Request ID) 생성 규칙은 UUID(Universally Unique IDentifier: 범용 고유 식별자) 규칙을 따릅니다. 테스트용 UUID는 다음을 참고하여 생성하시기 바랍니다.

Transaction 전송 시에 UUID는 다르게 발송해야 합니다. 여러 번 테스트가 필요하면, 기존에 쓴 UUID에서 한 두개 문자만 변경한 후 테스트를 하세요.
