Takoyaki NFT

Welcome to the Takoyaki NFT library.

The goal of this library is to simplify interacting with the Takoyaki NFTs (Non-Fungible Tokens) on the Ethereum blockchain.

It contains the art asset rendering and trait computation functions needed to create client side SVG files for a given set of traits as well as the algorithms required to compute the traits from the on-chain data for a given Takoyaki.

Installing

/home/ricmoo/my-project> npm install --save takoyaki
const Takoyaki = require("takoyaki");

API

Rendering and Display Logic

Takoyaki.getSvg ( traits [ , backgroundColor ] ) => string

Create an SVG string for the appearance traits and optionally a backgroundColor (100% transparent, by default).

Takoyaki.getLabelColor ( label [ , saturation = 90 [ , luminence = 90 ] ] ) => string

Create an hsl(hue, saturation, luminence) color for the given label, which can be used for the background (sat = 90, lum = 90), or adding lighter/darker features, such as borders or text.

Takoyaki.SVG => string

The raw SVG that is processed to generate individual Takoyaki.

Traits

Takoyaki.getTraits ( [ genes ] ) => Traits

Compute the traits for a given set of genes, which should include a salt and seeds, which is an Array of up to 5 bytes6. If genes is omitted, a random set of traits is returned.

URLs and Labels

Takoyaki.urlToLabel ( hostname ) => string

Converts a hostname into the label, accounting for Punycode, so international and emoji names can be used.

Takoyaki.labelToUrl ( label ) => string

Converts a label into the Punycode hostname.

Takoyaki.nomarlizeLabel ( label ) => string

Normalize a label string, folding cases, UTF-8 composition and UTF-8 canonical representation as per punycode.

Takoyaki Contract

Takoyaki.connect ( providerOrProvider ) => TakoyakiContract

Return a Contract instance to interact with the blockchain values for Takoyaki Tokens.

contract.getTransactions ( label , owner , salt [ , prefundRevealer ] ) => Object

Returns an object with two transaction Objects, commit and reveal, which can be signed and sent to the network to commit and reveal. You MUST have a delay of at least 4 blocks between commit and reveal, and no more than 5,760 blocks.

This is the recommended method of using this library.

contract.getTraits ( tokenId [ , hints ] ) => Promise:Traits

Returns the traits for a given Takoyaki. The hints can be used to save network calls and to indicate information which is not yet available, such as the salt prior to the reveal.

contract.tokenURI ( tokenId ) => Promise:string

Returns the URL of a JSON description of the token

contract.totalSupply ( ) => Promise:BigNumber

Returns the total number of Takoyaki currently issued. This may be higher than the actual number, since the total supply is only decremented for expired Takoyaki Tokens when destroy is called them.

contract.symbol => string

Returns "TAKO"

contract.name => string

Returns "Takoyaki"

contract.fee ( ) => Promise:BigNumber

Returns the fee for a Takoyaki.

contract.isValidLabel ( label ) => boolean

Returns true if and only if the label is valid.

contract.getTakoyaki ( tokenId ) => Promise:Object

TODO

contract.commit ( blindedCommit , prefundedRevealer , prefundAmount ) => Promise:TransactionResponse

TODO

contract.cancelCommit ( blindedCommit ) => TransactionResponse

TODO

contract.reveal ( label , owner , salt ) => TransactionResponse

TODO

contract.renew ( tokenId ) => TransactionResponse

TODO

contract.reclaim ( tokenId , owner ) => TransactionResponse

TODO

contract.destroy ( tokenId ) => TransactionResponse

TODO

contract.available ( tokenId ) => Promise:boolean

TODO

contract.getTakoyaki ( tokenId ) => Promise:Object

TODO

contract.ownerOf ( tokenId ) => Promise:string

Returns the owner the tokenId Takoyaki.

contract.balanceOf ( address ) => Promise:BigNumber

Returns the number of Takoyaki tokens that address owns.

contract.approve ( toAddress , tokenId ) => Promise:TransactionResponse

TODO

contract.getApproved ( tokenId ) => Promise:string

TODO

contract.setApprovedForAll ( toAddress , isApproved ) => Promise:TransactionResponse

TODO

contract.isApprovedForAll ( owner , operator ) => Promise:boolean

TODO

contract.transferFrom ( fromAddress , toAddress, tokenId ) => Promise:TransactionResponse

TODO

contract.safeTransferFrom ( fromAddress , toAddress , tokenId , data ) => Promise:TransactionResponse
