Constructors

constructor

new MRC721(address, provider): MRC721
Parameters
- address: string
- provider: Provider
Returns MRC721
Overrides MetrixContract.constructor
- Defined in src/metriverse/token/MRC/MRC721.ts:10

Properties

abi

abi: any[]

address

address: string

bytecode

bytecode: undefined | string

provider

provider: Provider

Methods

approve

approve(to, tokenId): Promise<Transaction>
Gives permission to to to transfer tokenId token to another account. The approval is cleared when the token is transferred.

Only a single account can be approved at a time, so approving the zero address clears previous approvals.

Requirements:
- The caller must own the token or be an approved operator.
- tokenId must exist.
Emits an Approval event.
Parameters
- to: string
- tokenId: bigint
Returns Promise<Transaction>
Implementation of IERC721Enumerable.approve
- Defined in src/metriverse/token/MRC/MRC721.ts:84

balance

balance(): Promise<bigint>
Get this contract balance

Returns Promise<bigint>
the satoshi balance of this contract
Inherited from MetrixContract.balance
- Defined in src/mrx/MetrixContract.ts:30

balanceOf

balanceOf(owner): Promise<bigint>
Returns the number of tokens in owner's account.
Parameters
- owner: string
Returns Promise<bigint>
Implementation of IERC721Enumerable.balanceOf
- Defined in src/metriverse/token/MRC/MRC721.ts:36

call

call(method, args): Promise<undefined | Result>
Perform calltocontract
Parameters
- method: string
  The contract method to call
- args: any[]
  The arguments
Returns Promise<undefined | Result>
see Result
Inherited from MetrixContract.call
- Defined in src/mrx/MetrixContract.ts:44

getApproved

getApproved(tokenId): Promise<string>
Returns the account approved for tokenId token.

Requirements:
- tokenId must exist.
Parameters

getEventLogs

getEventLogs(): Promise<EventLogs>
Get receipts from a transaction

Returns Promise<EventLogs>
an EventLogs object
Inherited from MetrixContract.getEventLogs
- Defined in src/mrx/MetrixContract.ts:94

isApprovedForAll

isApprovedForAll(owner, operator): Promise<boolean>
Returns if the operator is allowed to manage all of the assets of owner.

name

name(): Promise<string>
Returns the token collection name.

Returns Promise<string>
Implementation of IERC721Enumerable.name
- Defined in src/metriverse/token/MRC/MRC721.ts:143

ownerOf

ownerOf(tokenId): Promise<string>
Returns the owner of the tokenId token.

Requirements:
- tokenId must exist.
Parameters

safeTransferFrom

safeTransferFrom(from, to, tokenId): Promise<Transaction>
Safely transfers tokenId token from from to to, checking first that contract recipients are aware of the ERC721 protocol to prevent tokens from being forever locked.

Requirements:
- from cannot be the zero address.
- to cannot be the zero address.
- tokenId token must exist and be owned by from.
- If the caller is not from, it must be have been allowed to move this token by either approve or setApprovalForAll.
- If to refers to a smart contract, it must implement IERC721Receiver-onERC721Received, which is called upon a safe transfer.
Emits a Transfer event.
Parameters
- from: string
- to: string
- tokenId: bigint
Returns Promise<Transaction>
Implementation of IERC721Enumerable.safeTransferFrom
- Defined in src/metriverse/token/MRC/MRC721.ts:50

safeTransferFromData

safeTransferFromData(from, to, tokenId, data): Promise<Transaction>
Safely transfers tokenId token from from to to.

Requirements:
- from cannot be the zero address.
- to cannot be the zero address.
- tokenId token must exist and be owned by from.
- If the caller is not from, it must be approved to move this token by either approve or setApprovalForAll.
- If to refers to a smart contract, it must implement IERC721Receiver-onERC721Received, which is called upon a safe transfer.
