Harmony Marketplace SDK
Harmony Marketplace SDK provides a collection of interfaces to interact with HRC721, HRC1155 and any Smart Contracts that extends those standards. This library was based on @harmony-js
Install
npm i harmony-marketplace-sdk
Usage
Node
// JavaScript
const { HRC721 } = require('harmony-marketplace-sdk')
// TypeScript
import { HRC721 } from 'harmony-marketplace-sdk'
Browser
Include the ESM module (harmony-marketplace-sdk.esm.js) and import using:
<script type="module">
import { HRC721 } from './harmony-marketplace-sdk.esm.js'
</script>
Wallet
Harmony Marketplace SDK provides three implementations of Wallet which help to create a Signer from a private key or mnemonic effortless.
Private Key
Implementation of the Wallet that uses a private key.
import { HttpProvider, WSProvider } from '@harmony-js/network'
import { PrivateKey, HarmonyShards, HARMONY_RPC_SHARD_0_URL, HARMONY_RPC_WS } from 'harmony-marketplace-sdk'
const privateKey = '45e497bd45a9049bcb649016594489ac67b9f052a6cdf5cb74ee2427a60bf25e'
// Using a HttpProvider with a string url.
const pk = new PrivateKey(new HttpProvider('https://api.harmony.one'), privateKey)
// Using a HttpProvider with a const from Harmony Marketplace SDK.
const pk = new PrivateKey(new HttpProvider(HARMONY_RPC_SHARD_0_URL), privateKey)
// Using a WSProvider with a string url.
const pk = new PrivateKey(new WSProvider('wss://ws.s0.t.hmny.io'), privateKey)
// Using a WSProvider with a const from Harmony Marketplace SDK.
const pk = new PrivateKey(new WSProvider(HARMONY_RPC_WS), privateKey)
// Using a provider with a pre-configuration from Harmony Marketplace SDK.
const pk = new PrivateKey(HarmonyShards.SHARD_0, privateKey)
Mnemonic Key
Implementation of the Wallet that uses a list of words for the mnemonic key.
import { HttpProvider, WSProvider } from '@harmony-js/network'
import { MnemonicKey, HarmonyShards, HARMONY_RPC_SHARD_0_URL, HARMONY_RPC_WS } from 'harmony-marketplace-sdk'
const mnemonic = 'glory seat canal seven erosion asset guilt perfect fluid dice floor unfold'
// Using a HttpProvider with a string url.
const mnemonicKey = new MnemonicKey(new HttpProvider('https://api.harmony.one'), { mnemonic })
// Using a HttpProvider with a const from Harmony Marketplace SDK.
const mnemonicKey = new MnemonicKey(new HttpProvider(HARMONY_RPC_SHARD_0_URL), { mnemonic })
// Using a WSProvider with a string url.
const mnemonicKey = new MnemonicKey(new WSProvider('wss://ws.s0.t.hmny.io'), { mnemonic })
// Using a WSProvider with a const from Harmony Marketplace SDK.
const mnemonicKey = new MnemonicKey(new WSProvider(HARMONY_RPC_WS), { mnemonic })
// Using a provider with a pre-configuration from Harmony Marketplace SDK.
const mnemonicKey = new MnemonicKey(HarmonyShards.SHARD_0, { mnemonic })
Simple Key
Implementation of the Wallet that does not use any pk or mnemonic.
import { HttpProvider, WSProvider } from '@harmony-js/network'
import { Key, HarmonyShards, HARMONY_RPC_SHARD_0_URL, HARMONY_RPC_WS } from 'harmony-marketplace-sdk'
// Using a HttpProvider with a string url.
const key = new Key(new HttpProvider('https://api.harmony.one'))
// Using a HttpProvider with a const from Harmony Marketplace SDK.
const key = new Key(new HttpProvider(HARMONY_RPC_SHARD_0_URL))
// Using a WSProvider with a string url.
const key = new Key(new WSProvider('wss://ws.s0.t.hmny.io'))
// Using a WSProvider with a const from Harmony Marketplace SDK.
const key = new Key(new WSProvider(HARMONY_RPC_WS))
// Using a provider with a pre-configuration from Harmony Marketplace SDK.
const key = new Key(HarmonyShards.SHARD_0)
// Add Private key manually
key.addByPrivateKey('45e497bd45a9049bcb649016594489ac67b9f052a6cdf5cb74ee2427a60bf25e')
HD Key
Implementation of a hierarchical deterministic (HD) wallet that uses a mnemonic to generate the derivative addresses.
import { HttpProvider, WSProvider } from '@harmony-js/network'
import { HDKey, HarmonyShards, HARMONY_RPC_SHARD_0_URL, HARMONY_RPC_WS } from 'harmony-marketplace-sdk'
const options = {
mnemonic: 'glory seat canal seven erosion asset guilt perfect fluid dice floor unfold',
index: 0,
numberOfAddresses: 1,
shardId: 0,
gasLimit: '1000000',
gasPrice: '2000000000',
}
// Using a HttpProvider with a string url.
const key = new HDKey(new HttpProvider('https://api.harmony.one'), options)
// Using a HttpProvider with a const from Harmony Marketplace SDK.
const key = new HDKey(new HttpProvider(HARMONY_RPC_SHARD_0_URL), options)
// Using a WSProvider with a string url.
const key = new HDKey(new WSProvider('wss://ws.s0.t.hmny.io'), options)
// Using a WSProvider with a const from Harmony Marketplace SDK.
const key = new HDKey(new WSProvider(HARMONY_RPC_WS), options)
// Using a provider with a pre-configuration from Harmony Marketplace SDK.
const key = new HDKey(HarmonyShards.SHARD_0, options)
Metamask Provider
Implementation a subclass of HttpProvider that takes window.ethereum as a parameter, each method of HttpProvider is implemented by this subclass by cascading the request appropriately to window.ethereum
import detectEthereumProvider from '@metamask/detect-provider'
import { MetamaskProvider } from 'harmony-marketplace-sdk'
const provider = await detectEthereumProvider()
// Using a MetamaskProvider with window or a detected provider.
const key = new Key(new MetamaskProvider(window.ethereum || provider))
Base Token
The BaseToken
is an extension over a regular Contract which is the Harmony recomendation for interact with smart contracts. This abstract class contains the core functionality for interact with Harmony Smart Contracts.
HRC20 API
The HRC20
implements the abstract class Base Token.
NOTE: The harmony explorer will look for a specific list of functions and events to identify HRC20 tokens. You can validate if the bytecode of your HRC20 is valid here.
Expected Methods: | Method | Description | | ------------- | ------------- | | totalSupply | Total amount of tokens stored by the contract. | | balanceOf | Returns the amount of tokens owned by account. | | transfer | Moves amount tokens from the caller’s account to another account. | | allowance | Returns the remaining number of tokens that spender will be allowed to spend on behalf of owner through transferFrom | | approve | Sets amount as the allowance of spender over the caller’s tokens. | | transferFrom | Moves amount tokens from an account to another account using the allowance mechanism. | | symbol | Returns the symbol of the token. | | name | Returns the name of the token. | | decimals | Returns the decimals places of the token. | | mint | Creates amount tokens and assigns them to account. | | burn | Destroys amount tokens from account. | | burnFrom | Destroys amount tokens from an account. |
Expected Events | Event | Description | | ------------- | ------------- | | Transfer | Emitted when a token id is transferred from an address to another. | | Approval | Emitted when owner enables approved to manage the tokenId token. |
You can find an example of HRC20 in this address 0x...0a0a.

HRC1155 API
The HRC1155
implements the abstract class Base Token.
NOTE: The harmony explorer will look for a specific list of functions and events to identify HRC1155 tokens. You can validate if the bytecode of your HRC1155 is valid here.
Expected Methods: | Method | Description | | ------------- | ------------- | | balanceOf | Returns the amount of tokens of a token type (id) owned by an account. | | balanceOfBatch | Batched version of balanceOf. | | safeTransferFrom | Transfers the amount of tokens of a token type (id) from an address to another address. | | safeBatchTransferFrom | Batched version of safeTransferFrom. | | setApprovalForAll | Grants or revokes permission to an operator to transfer the caller’s tokens. | | isApprovedForAll | Returns true if an operator is approved to transfer the tokens of an account. | | owner | Returns the address of the current contract owner. | | tokenURIPrefix | Returns the token URI prefix | | contractURI | Returns a URL for the storefront-level metadata for your contract. | | tokenURI | Returns the Uniform Resource Identifier (URI) for a token. | | totalSupply | Total amount of tokens with a given token id | | symbol | Returns the token collection symbol. | | name | Returns the token collection name. | | mint | Creates the amount of tokens of a token type (id), and assigns them to an account. | | mintBatch | Batched version of mint |
Expected Events | Event | Description | | ------------- | ------------- | | TransferSingle | Emitted when a token id are transferred from an address to another by operator. | | TransferBatch | Emitted when a token ids are transferred from an address to another by operator. |
You can find an example of HRC1155 in this address 0x...b264.
