SDK Integration

Quick guide to integrate the Asset Tokenization Studio SDK in your project.

Installation​

npm install @hashgraph/asset-tokenization-sdk

Setup​

1. Initialize the Network​

import { Network, InitializationRequest } from "@hashgraph/asset-tokenization-sdk";

const initRequest = new InitializationRequest({
  network: "testnet",
  mirrorNode: {
    baseUrl: "https://testnet.mirrornode.hedera.com/api/v1/",
    apiKey: "",
    headerName: "",
  },
  rpcNode: {
    baseUrl: "https://testnet.hashio.io/api",
    apiKey: "",
    headerName: "",
  },
  configuration: {
    resolverAddress: "0.0.7707874", // See deployed-addresses.md
    factoryAddress: "0.0.7708432",
  },
});

await Network.init(initRequest);

2. Connect a Wallet​

Hedera WalletConnect 2.0 (HashPack, Blade, and other WC-compatible wallets)​

import { ConnectRequest, SupportedWallets } from "@hashgraph/asset-tokenization-sdk";

const connectRequest = new ConnectRequest({
  network: "testnet",
  mirrorNode: {
    baseUrl: "https://testnet.mirrornode.hedera.com/api/v1/",
    apiKey: "",
    headerName: "",
  },
  rpcNode: {
    baseUrl: "https://testnet.hashio.io/api",
    apiKey: "",
    headerName: "",
  },
  wallet: SupportedWallets.HWALLETCONNECT,
  hwcSettings: {
    projectId: "your_walletconnect_project_id", // from https://cloud.walletconnect.com
    dappName: "My ATS App",
    dappDescription: "Asset Tokenization Studio dApp",
    dappURL: "https://example.com",
    dappIcons: ["https://example.com/icon.png"],
  },
});

const walletData = await Network.connect(connectRequest);

Note: HashPack and Blade wallets connect via Hedera WalletConnect 2.0 (SupportedWallets.HWALLETCONNECT). You need a WalletConnect projectId from cloud.walletconnect.com.

MetaMask​

const connectRequest = new ConnectRequest({
  // ...network config...
  wallet: SupportedWallets.METAMASK,
});

const walletData = await Network.connect(connectRequest);

Basic Usage​

Create an Equity Token​

import { Equity, CreateEquityRequest } from "@hashgraph/asset-tokenization-sdk";

const request = new CreateEquityRequest({
  tokenName: "Acme Corporation Common Stock",
  tokenSymbol: "ACME",
  tokenDecimals: 0,
  tokenTotalSupply: 1000000,
  isin: "US9311421039",
});

const response = await Equity.create(request);
console.log("Token created:", response.security.tokenId);

Transfer Tokens​

import { Security, TransferRequest } from "@hashgraph/asset-tokenization-sdk";

const transferRequest = new TransferRequest({
  tokenId: "0.0.1234567",
  targetId: "0.0.7654321",
  amount: 100,
});

const success = await Security.transfer(transferRequest);

Grant KYC​

import { Kyc, GrantKycRequest } from "@hashgraph/asset-tokenization-sdk";

const grantKycRequest = new GrantKycRequest({
  tokenId: "0.0.1234567",
  targetId: "0.0.7654321",
  vcData: "verifiable_credential_data",
});

await Kyc.grantKyc(grantKycRequest);
