위 소스코드를 통해서 KIP7을 발행하려합니다.

contract KIP7Token is KIP7Mintable, KIP7Burnable, KIP7Pausable, KIP7Metadata {  
constructor(string memory name, string memory symbol, uint8 decimals, uint256 initialSupply) KIP7Metadata(name, symbol, decimals) public {  
\_mint(msg.sender, initialSupply);  
}  
}

상기 코드에서 토큰 이름 및 심볼, 소수점, 초기유통량을 설정해서 발행하려면 어떻게 해야하는지 안내 부탁드릴게요.

안녕하세요 🙂 질문주셔서 감사합니다.

먼저 caver-js에서는 KIP-7 token contract를 쉽게 배포할 수 있는 기능을 제공합니다.  
caver-js v1.5.0 이상의 버전을 사용하는 경우에는 [caver.kct.kip7.deploy](https://docs.klaytn.com/bapp/sdk/caver-js/api-references/caver.kct/kip7#caver-klay-kip7-deploy)를 사용할 수 있으며 v1.5.0 이전 버전의 경우 [caver.klay.KIP7.deploy](https://docs.klaytn.com/bapp/sdk/caver-js/v1.4.1/api-references/caver.klay.kip7#caver-klay-kip7-deploy)을 사용하실 수 있습니다.

deploy 함수를 호출할 때에 오브젝트 내부에 name, symbol, decimals, initialSupply를 정의하실 수 있으며 사용 방법은 아래 예제를 참고해 주세요.

```
// caver-js v1.5.0 이상 버전
const caver = new Caver('https://api.baobab.klaytn.net:8651/')
const deployer = caver.wallet.add(
    caver.wallet.keyring.createFromPrivateKey('0x0c66be6f6a0c539be9e99d883e897cdc10cb016a958c9a61485ae57cace5d7bf')
)

const kip7 = await caver.kct.kip7.deploy(
    {
        name: 'TokenName',
        symbol: 'TKN',
        decimals: 18,
        initialSupply: '100000000000000000000',
    },
    deployer.address
)
console.log(`Deployed KIP-7 token contract address: ${kip7.options.address}`)

console.log(`Token name: ${await kip7.name()}`)
console.log(`Token symbol: ${await kip7.symbol()}`)
console.log(`Token decimals: ${await kip7.decimals()}`)
console.log(`Token totalSupply: ${await kip7.totalSupply()}`)

```

위의 예제 코드는 caver-js v1.5.0 이상의 버전에서 동작하는 코드입니다.  
v1.5.0 이전 버전의 경우 아래의 예제를 참고해 주세요.

```
const caver = new Caver('https://api.baobab.klaytn.net:8651/')
const deployer = caver.klay.accounts.wallet.add('0x0c66be6f6a0c539be9e99d883e897cdc10cb016a958c9a61485ae57cace5d7bf')

const kip7 = await caver.klay.KIP7.deploy(
    {
        name: 'TokenName',
        symbol: 'TKN',
        decimals: 18,
        initialSupply: '100000000000000000000',
    },
    deployer.address
)
console.log(`Deployed KIP-7 token contract address: ${kip7.options.address}`)

console.log(`Token name: ${await kip7.name()}`)
console.log(`Token symbol: ${await kip7.symbol()}`)
console.log(`Token decimals: ${await kip7.decimals()}`)
console.log(`Token totalSupply: ${await kip7.totalSupply()}`)
```

답장 감사합니다.  
caver를 통해 컨트렉트를 deploy하면 scope에서 컨트렉트 verification을 위해 요구하는

- **Contract Address**
- **Environment of the smart Contract**
  - Compiler Type
  - Compiler Version
  - Open Source Licence Type

- **Smart Contract Detail**
  - Optimization
  - Source code  
(or upload all files)

- **ABI-encoded value**
- **EVM version**

위 사항들을 모두 제출할 수 있나요?  
클레이튼 ide을 통해 직접 컴파일하는 방식이 아니라서 소스코드나 emv version 등에 있어서 제출이 조금 어려울 수 있을 것 같은데 다른 부분 수정없이 caver.kct.kip7.deploy 를 사용하면 verification을 용이하게 할 수 있는지 답변 부탁드릴게요.

네 안녕하세요. caver-js에서 컴파일해서 사용하고 있는 KIP-7에 대한 정보를 말씀드리겠습니다.

await 키워드는 async 함수에서만 사용 가능합니다.  
async함수가 아닌 경우 `then`을 사용해 주시거나 event emitter를 사용하여 구현하시면 됩니다.

안녕하세요, 시간이 지나 다시 한번 해당 정보 안내 부탁드리겠습니다.  
소스코드의 경우 url이 변경된 것 같습니다.  
컨트렉은 당시 caver.kct.kip7.deploy 로 배포했었습니다.

- Compiler version
- Open Source License Type
- Optimization 여부
- Optimization Runs: Solidity에서 200이 default 값입니다. 컴파일 과정에서 변경을 한 경우 알려주셔야 합니다.
- Source code: 파일이 여러개인 경우 flatten해서 싱글 파일 하나로 만들어주셔야 합니다. 실제 체인상에 디플로이된 코드를 flatten해서 주셔야 합니다. (반드시 컴파일된 형태로 전달 부탁드립니다.)

소스코드를 안내해주신 깃헙에서 받아 하나의 파일로 만들었습니다.  
해당 파일로 Klaytn IDE 에서 정상적으로 컴파일되고 기 배포된 스마트컨트렉트 주소에 연결해 함수들 작동하는 것까지 확인했습니다.  
해당 소스코드를 오지스 측에 전달했는데 verification 진행 시 Byte code and transaction input data do not match. 오류 발생한다고 하네요. 어떤 부분이 잘못되었는지 안내 가능할까요?

저렇게만 봐서는 어떤 부분이 잘못되었는지 안내드리기 어렵습니다.  
오지스측에 문의해서 어떤 데이터가 다른건지 문의하시기 바랍니다.

그리고 혹시 스마트 컨트랙트를 언제 배포하셨을까요?  
컨트랙트를 꽤 이전에 배포한 경우 현재 제공되는 소스코드가 아닐 수도 있습니다.
