Installation

We recommend using Node.js version 16.

yarn add @onblockio/ghostmarket-sdk-js

or if using npm

npm install --save @onblockio/ghostmarket-sdk-js

Install web3 if you don't have it already.

Getting started

EVM quickstart

To get started on EVM, you can use either a read only provider, a web3 provider (ex metamask) or a private key (to be stored in .env file, see .env.example for a reference).

import Web3 from 'web3'
import { GhostMarketSDK, Chain, TESTNET_API_URL, MAINNET_API_URL } from 'ghostmarket-sdk-js';
// if using EVM private key or mnemonic hdwallet-provider is required
// import HDWalletProvider from '@truffle/hdwallet-provider'


// Variables
const apiKey = process.env.GM_API_KEY // GhostMarket API KEY if you have one
const privateKey = process.env.PRIVATE_KEY // private key to use - only for private key provider
const rpcUrl = process.env.RPC_URL // RPC to use, ex 'https://mainnet.infura.io'
const environment = MAINNET_API_URL // GhostMarket Infrastructure - MAIN_ENVIRONMENT or TEST_ENVIRONMENT
const chainName = Chain.ETHEREUM // see below for chain values

/* chainName values : 
    Chain.ETHEREUM / Chain.ETHEREUM_TESTNET
    Chain.POLYGON / Chain.POLYGON_TESTNET
    Chain.BSC / Chain.BSC_TESTNET
    Chain.AVALANCHE / Chain.AVALANCHE_TESTNET
    Chain.BASE / Chain.BASE_TESTNET
    Chain.SHARDEUM / Chain.SHARDEUM_TESTNET
    Chain.NEOX / Chain.NEOX_TESTNET
    Chain.BLAST / Chain.BLAST_TESTNET
    */

// SDK config options.
const sdkConfig = {
    apiKey,
    rpcUrl,
    environment,
    chainName,
}

// Option 1 - readonly provider, only reads the network state. Can not sign transactions
const customProvider = new Web3.providers.HttpProvider(rpcUrl)
const address = ''
// Option 2 - metamask provider
const customProvider = window.ethereum
const address = await ethereum.request({
    method: 'eth_requestAccounts',
  })[0];
// Option 3 - private key
const customProvider = new HDWalletProvider(privateKeys: [privateKey], providerOrUrl: rpcUrl)
const address = customProvider.addresses[0]
// Create instance of GhostMarketSDK - EVM
const gmSDK = new GhostMarketSDK(customProvider, sdkConfig);
// Start and stop provider engine - when using HDWalletProvider
// customProvider.engine.start();
// your code here
// customProvider.engine.stop();

// All set - use the object gmSDK to access GhostMarket SDK

Neo N3 quickstart

To get started on Neo N3, you can use either a NEP-12 provider (ex neoline or o3) or a private key (to be stored in .env file, see .env.example for a reference).

import { GhostMarketN3SDK, Chain, TESTNET_API_URL, MAINNET_API_URL } from 'ghostmarket-sdk-js';

// Variables
const apiKey = process.env.GM_API_KEY // GhostMarket API KEY if you have one
const privateKey = process.env.PRIVATE_KEY // private key to use - only for Neo N3 private provider
const rpcUrl = process.env.RPC_URL // RPC to use instead of default ones
const environment = MAINNET_API_URL // GhostMarket Infrastructure - MAIN_ENVIRONMENT or TEST_ENVIRONMENT
const chainName = Chain.NEO3 // see below for chain values

/* chainName values : 
    Chain.NEO3 / Chain.NEO3_TESTNET
    */

// SDK config options.
const sdkConfig = {
    apiKey,
    rpcUrl,
    environment,
    chainName,
    privateKey
}

// Option 1 - neoline
const customProvider = 'neoline'
// Option 2 - o3
const customProvider = 'o3'
// Option 3 - private key
const customProvider = 'private'
// Create instance of GhostMarketN3SDK - Neo N3
const gmSDK = new GhostMarketN3SDK(customProvider, sdkConfig);
// Connected address (neoline / o3)
const address = (await gmSDK.getProvider().getAccount()).address

// All set - use the object gmSDK to access GhostMarket SDK

Usage Common

// Fetch 10 GhostMarket assets.
const { assets } = await gmSDK.api.getAssetsV2({ size: 10 })
console.info(assets)

Getting events

// Fetch 10 GhostMarket events.
const { events } = await gmSDK.api.getEventsV2({ size: 10 })

const availableIncentives = incentives[5] ? incentives[5].value : 0 // Neo N3
console.info(availableIncentives)

Set contract royalties

const contractAddress = '0x....'
const royaltiesArray = [{address, value: 1000}] // array of recipient/value array (in bps).
const royalties = await gmSDK.setRoyaltiesForContract(contractAddress, royaltiesArray, {from: address})

console.info(signed)

Usage EVM

You can override automatic calculation of gas price if you add it to the last argument object on each transaction requiring signature. Example when wrapping a token:

instead of const wrap = await gmSDK.wrapToken(amount, isWrap, {from: address}) simply do const wrap = await gmSDK.wrapToken(amount, isWrap, {from: address, gasPrice: 50000}) if you want to override gas price to 50000.

Buying NFT

const orderDetails = { 
    baseContract: '0x....', // order maker base contract address.
    baseTokenId: '1', // order maker NFT tokenId - set to the one to offer for a collection offer.
    baseTokenAmount: 1, // order maker amount - optional - only needed for ERC1155 otherwise default to 1.
    quoteContract: '0x....', // order maker quote contract address - use 0x for native currency (ex. ETH).
    quotePrice: '1', // order maker price - in wei.
    makerAddress: '0x....', // order maker.
    type: 1, // order maker type 1 - listing, 2 - offer.
    startDate: 0, // order maker start date.
    endDate: 0, // order maker end date.
    salt: '0x....', // order maker salt.
    signature: '0x....', // order maker signature.
}
const buying = await gmSDK.matchOrders(orderDetails, {from: address})
console.info(buying)

Listing NFT fixed price

const startDate = parseInt((new Date().getTime() / 1000).toString())
const orderDetails = [{ 
    baseContract: '0x....', // order base contract address - nft contract for listing.
    baseTokenId: '1', // order NFT tokenId - token id for listing - set to empty for collection offer.
    baseTokenAmount: 1, // order amount - only needed for ERC1155 otherwise default to 1.
    quoteContract: '0x....', // order quote contract address - currency accepted for listing - use 0x for native currency (ex. ETH).
    quotePrice: '1', // order price - in wei.
    makerAddress: '0x....', // order maker.
    type: 1, // 1 - listing, 2 - offer, 3 - collection offer.
    startDate, // order start date.
    endDate: startDate + (3600 * 24) // order end date.
}]
const listing = await gmSDK.createOrder(orderDetails)
console.info(listing)

Cancel Listing NFT

const orderDetails = [{ 
    baseContract: '0x....', // order base contract address - nft contract for listing.
    baseTokenId: '1', // order NFT tokenId - token id for listing - set to empty for collection offer.
    baseTokenAmount: 1, // order amount - only needed for ERC1155 otherwise default to 1.
    quoteContract: '0x....', // order quote contract address - currency accepted for listing - use 0x for native currency (ex. ETH).
    quotePrice: '1', // order price - in wei.
    makerAddress: '0x....', // order maker.

    startDate: 0, // order start date.
    endDate: 0, // order end date.
    salt: '0x....' // required for cancellation, use the salt from the order/offer.
}]
const cancel = await gmSDK.bulkCancelOrders(orderDetails, {from: address})
console.info(cancel)

Edit listing price

Note: edit listing price does not cancel current order, it just hides it on API and exposes the new one only, but the old one can still be matched later. Only a true cancellation will make it un matcheable - only supported for ERC721.

const orderDetails = [{ 
    baseContract: '0x....', // order base contract address - nft contract for listing.
    baseTokenId: '1', // order NFT tokenId - token id for listing - set to empty for collection offer.
    baseTokenAmount: 1, // order amount - only needed for ERC1155 otherwise default to 1.
    quoteContract: '0x....', // order quote contract address - currency accepted for listing - use 0x for native currency (ex. ETH).
    quotePrice: '1', // order new price - in wei - has to be lower than current price.
    makerAddress: '0x....', // order maker.
    type: 1, // 1 - listing, 2 - offer, 3 - collection offer.
    startDate: 0, // order start date.
    endDate: 0, // order end date.
    salt: '0x....' // required for edit, use the salt from the order/offer.
