caver.kct.kip17
caver.kct.kip17
helps you easily handle a smart contract that implements KIP-17 as a JavaScript object on the kaia 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 Kaia 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 Kaia Improvement Proposals.
caver.kct.kip17.deploy β
caver.kct.kip17.deploy(tokenInfo, deployer)
Deploys the KIP-17 token contract to the kaia 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 kaia 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 KAIA 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.

kip17.transferFrom β
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. |
NOTE The tokenId
parameter accepts 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

kip17.safeTransferFrom β
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. |
NOTE The tokenId
parameter accepts 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 KIP-17 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.
