caver.kct.kip37

caver.kct.kip37은 JavaScript의 객체로서 KIP-37을 구현하는 스마트 컨트랙트를 Klaytn 블록체인 플랫폼에서 쉽게 다룰 수 있도록 도와줍니다.

caver.kct.kip37는 KIP-37 토큰 컨트랙트를 구현하기 위해 caver.contract를 상속합니다. caver.kct.kip37caver.contract와 동일한 속성값들을 가지며, 추가 기능 구현을 위한 메서드를 더 가지고 있습니다. 이 장은 caver.kct.kip37 메서드들 중 오직 새롭게 추가된 것만을 소개합니다.

The code that implements KIP-37 for caver-js is available on the Klaytn Contracts Github Repo. KIP-37 for caver-js supports Ownable interface. Using this, you can designate a contract owner when deploying a contract

For more information about KIP-37, see Klaytn Improvement Proposals.

참고 caver.kct.kip37는 caver-js v1.5.7부터 지원됩니다.

caver.kct.kip37.deploy

caver.kct.kip37.deploy(tokenInfo, deployer)

KIP-37 토큰 컨트랙트를 Klaytn 블록체인에 배포합니다. caver.kct.kip37.deploy를 사용해 배포한 컨트랙트는 KIP-37 표준을 따르는 멀티 토큰입니다.

성공적으로 배포된 후, 프로미스는 새로운 KIP37 인스턴스를 반환할 것입니다.

Parameters

NameTypeDescription

tokenInfo

object

Klaytn 블록체인에 KIP-37 토큰 컨트랙트를 배포하는 데 필요한 정보입니다. See the below table for the details.

deployer

string | object

KIP-37 토큰 컨트랙트를 배포할 keyring 인스턴스의 계정 주소입니다. This address must have enough KLAY to deploy. See Keyring for more details. 트랜잭션 전송 시 사용할 필드를 자체적으로 정의하고 싶다면 객체 타입을 매개변수로 전달하면 됩니다. KIP-37 컨트랙트 배포 시 수수료 위임을 이용하고 싶다면, 객체 내 수수료 위임과 관련된 필드를 정의할 수 있습니다. 객체에 정의될 수 있는 필드에 대해서는 create의 매개변수 설명을 참고하십시오.

The tokenInfo object must contain the following:

NameTypeDescription

uri

string

The URI for all token types, by relying on the token type ID substitution mechanism.

Return Value

PromiEvent: 이벤트 이미터와 결합된 프로미스이며 새로운 KIP37 인스턴스를 반환합니다. Additionally, the following events can occur:

NameTypeDescription

transactionHash

string

Fired right after the transaction is sent and a transaction hash is available.

receipt

object

Fired when the transaction receipt is available. If you want to know about the properties inside the receipt object, see getTransactionReceipt. KIP37 인스턴스의 영수증은 'logs' 속성 대신에 ABI로 파싱된 'events' 속성을 가지고 있습니다.

error

Error

Fired if an error occurs during sending.

Token Enrollment

  1. To enroll a token on a block explorer, the contract creator must fill out a submission request form. Make note of the specified information required on the form.

kip37.safeTransferFrom

kip37.safeTransferFrom(from, recipient, id, amount, data [, sendParam])

Safely transfers the given amount tokens of specific token type id from from to the recipient.

The address that was authorized to send the owner's token (the operator) or the token owner him/herself is expected to execute this token transfer transaction. Thus, an authorized address or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip37.options.from. Unless both sendParam.from and kip37.options.from are provided, an error would occur.

If the recipient was a contract address, it should implement IKIP37Receiver.onKIP37Received. Otherwise, the transfer is reverted.

Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the transaction sender.

Parameters

NameTypeDescription

from

string

토큰을 소유한 계정 주소입니다. 이 계정 주소 잔액에서 allowance(kip7Instance.approve)를 사용해 토큰이 보내집니다.

recipient

string

The address of the account to receive the token.

id

BigNumber | string | number

전송할 토큰 ID입니다.

amount

BigNumber | string | number

전송할 토큰 수량입니다.

data

Buffer | string | number

(optional) The optional data to send along with the call.

sendParam

object

(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of kip37.create.

NOTE The id and amount parameters accept number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.

Return Value

Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP37 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

kip37.safeBatchTransferFrom

kip37.safeBatchTransferFrom(from, recipient, ids, amounts, data [, sendParam])

Safely batch transfers of multiple token ids and values from from to the recipient.

The address that was approved to send the owner's token (the operator) or the token owner him/herself is expected to execute this token transfer transaction. Thus, an approved address or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip37.options.from. Unless both sendParam.from and kip37.options.from are provided, an error would occur.

If the recipient was a contract address, it should implement IKIP37Receiver.onKIP37Received. Otherwise, the transfer is reverted.

Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the transaction sender.

Parameters

NameTypeDescription

from

string

The address of the account that owns the token to be sent with allowance mechanism.

recipient

string

The address of the account to receive the token.

ids

Array

전송할 토큰 ID의 배열입니다.

amounts

Array

전송하고자 하는 토큰 수량의 배열입니다.

data

sendParam

object

(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of kip37.create.

NOTE The ids and amounts array parameters accept number type as an element in array, but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.

Return Value

Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP37 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

kip37.mint

kip37.mint(to, id, value [, sendParam])

Mints the token of the specific token type id and assigns the tokens according to the variables to and value. The mint function allows you to mint specific token to multiple accounts at once by passing arrays to to and value as parameters.

Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the transaction sender.

Parameters

NameTypeDescription

to

string | Array

토큰이 발행될 계정의 주소 또는 주소들의 배열입니다.

id

BigNumber | string | number

발행할 토큰 ID입니다.

value

BigNumber | string | number | Array

kip37.mintBatch kip37.mintBatch

kip37.mintBatch(to, ids, values [, sendParam])

Mints the multiple KIP-37 tokens of the specific token types ids in a batch and assigns the tokens according to the variables to and values.

Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the transaction sender.

Parameters

NameTypeDescription

to

string

토큰들이 발행될 계정 주소입니다.

ids

Array

발행할 토큰 ID들의 배열입니다.

values

Array

발행할 토큰 수량들의 배열입니다.

sendParam

object

(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of kip37.create.

NOTE The ids and values array parameters accept number type as an element in array, but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.

NOTE If sendParam.from or kip37.options.from were given, it should be a minter with MinterRole.

Return Value

Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP37 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

Example

> kip37.mintBatch('0x{address in hex}', [1, 2], [100, 200], { from: '0x{address in hex}' }).then(console.log)
