caver.kct.kip17

caver.kct.kip17 helps you easily handle a smart contract that implements KIP-17 as a JavaScript object on the Klaytn blockchain.

The caver.kct.kip17 inherits caver.contract to implement the KIP-17 token contract. The caver.kct.kip17 holds the same properties of caver.contract whereas there are additional methods to implement extra features. This section only introduces the newly added bound methods of the caver.kct.kip17.

The code that implements KIP-17 for caver-js is available on the Klaytn Contracts Github Repo. KIP-17 for caver-js supports Ownable interface. Using this, you can designate a contract owner when deploying a contract

For more information about KIP-17, see Klaytn Improvement Proposals.

caver.kct.kip17.deploy


caver.kct.kip17.deploy(tokenInfo, deployer)

Deploys the KIP-17 token contract to the Klaytn blockchain. A contract deployed using caver.kct.kip17.deploy is a non-fungible token that follows the KIP-17 standard.

After successful deployment, the promise will be resolved with a new KIP17 instance.

Parameters

Name	Type	Description
tokenInfo	object	The information needed to deploy KIP-17 token contract on the Klaytn blockchain. See the below table for the details.
deployer	string \| object	The address in the keyring instance to deploy the KIP-17 token contract. This address must have enough KLAY to deploy. See Keyring for more details. If you want to define your fields to use when sending transactions, you can pass the object type as a parameter. If you want to use Fee Delegation when deploying KIP-17 contracts, you can define the fields related to fee delegation in the object. For the use of these fields, refer to the parameter description of approve.

The tokenInfo object must contain the following:

Name	Type	Description
name	string	The name of the token.
symbol	string	The symbol of the token.

Return Value

PromiEvent: A promise combined event emitter, which is resolved with a new KIP17 instance. Additionally, the following events can occur:

Name	Type	Description
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. Receipts from KIP17 instances have an 'events' attribute parsed via abi instead of a 'logs' attribute.
error	Error	Fired if an error occurs during sending.

Token Enrollment

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.

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

Parameters

Name	Type	Description
to	string	The address of the account who spends tokens in place of the owner.
tokenId	BigNumber \| string \| number	The id of the token the spender is allowed to use.
sendParam	object	(optional) An object with defined parameters for sending a transaction.

The sendParam object can contain the following:

Name	Type	Description
from	string	(optional) The address from which the transaction should be sent. If omitted, it will be set by `kip17.options.from`. If neither of `from` in `sendParam` object nor `kip17.options.from` were not provided, an error would occur.
gas	number \| string	(optional) The maximum gas provided for this transaction (gas limit). If omitted, it will be set by caver-js via calling `kip17.methods.approve(spender, tokenId).estimateGas({from})`.
gasPrice	number \| string	(optional) The gas price in peb to use for this transaction. If omitted, it will be set by caver-js via calling `caver.klay.getGasPrice`.
value	number \| string \| BN \| BigNumber	(optional) The value to be transferred in peb.

feeRatio	string	(optional) The ratio of the transaction fee the fee payer will be burdened with. If `feeDelegation` is `true` and `feeRatio` is set to a valid value, a partial fee delegation transaction is used. The valid range of this is between 1 and 99. The ratio of 0, or 100 and above are not allowed. If omitted, `kip17.options.feeRatio` will be used.

NOTE feeDelegation, feePayer and feeRatio are supported since caver-js v1.6.1.

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 KIP-17 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

kip17.transferFrom


kip17.transferFrom(from, to, tokenId [, sendParam])

Transfers the token of the given token id, tokenId from the token owner's balance to another address. The address that was authorized to send the token owner's token (the operator) or the token owner him/herself is expected to execute this token transfer transaction. Thus, an authorized account or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip17Instance.options.from. Unless both sendParam.from and kip17Instance.options.from are provided, an error would occur. It is recommended to use safeTransferFrom whenever possible instead of this method.

Note that sending this transaction will charge the transaction fee to the transaction sender.

Parameters

Name	Type	Description
from	string	The address of the owner or the approved operator of the given token.
to	string	The address of the account to receive the token.
tokenId	BigNumber \| string \| number	The id of the token you want to transfer.
sendParam	object	(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of approve.

Return Value

Example


// Send via a sendParam object with the from field given 
> kip17.transferFrom('0x{address in hex}', '0x{address in hex}', 2, { from: '0x{address in hex}' }).then(console.log)

kip17.safeTransferFrom


kip17.safeTransferFrom(from, to, tokenId [, data] [, sendParam])

Safely transfers the token of the given token id tokenId from the token owner's balance to another address. The address that was authorized to send the token 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 kip17Instance.options.from. Unless both sendParam.from and kip17Instance.options.from are provided, an error would occur.

If the to is a contract address, it must implement IKIP17Receiver.onKIP17Received. otherwise, the transfer is reverted.

Note that sending this transaction will charge the transaction fee to the transaction sender.

Parameters

Name	Type	Description
from	string	The address of the owner or the approved operator of the given token.
to	string	The address of the account to receive the token.
tokenId	BigNumber \| string \| number	The id of the token you want to transfer.
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 approve.

Return Value

Example


// Send via a sendParam object with the from field given (without data)
