Deploying Contracts

Learn how to deploy a contract to multiple chains with Holograph SDK.

Prerequisites

To get the most out of this guide, make sure to:

• Configure Holograph SDK

1. Deploy to Primary Chain

src/holograph/deploy.ts

import { HolographERC721Contract } from "@holographxyz/sdk";
import { networks } from "@holographxyz/networks";

import { wallet } from "./config";

const myContract = new HolographERC721Contract({
  contractInfo: {
    name: "NFTs Without Boundaries",
    symbol: "HOLO",
    royaltiesPercentage: 2000, // 20%.
  },
  primaryChainId: networks.polygon.chain,
});

const signatureData = await myContract.signDeploy(wallet);

const { contractAddress, txHash } = await myContract.deploy(signatureData);

For more information, check out the HolographERC721Contract class reference.

2. Deploy to Multiple Chains

Option 1: Using deploy method again:

src/holograph/deploy.ts

const avalancheSignatureData = await myContract.signDeploy(
  wallet,
  networks.avalanche.chain
);

await myContract.deploy(avalancheSignatureData);

Option 2 (WIP): Using deployBatch method:

src/holograph/batch-deploy.ts

const signatureData = await myContract.signDeployBatch(wallet, [
  networks.polygon.chain,
  networks.avalanche.chain,
  networks.binanceSmartChain.chain,
  networks.arbitrumOne.chain,
]);

await myContract.deployBatch(signatureData);

⚠️ Warning: deployBatch is still under development.

Congrats! You have deployed an omnichain contract!

3. Deploy Multichain Open Edition (MOE)

Multichain open editions enable users to mint NFTs on multiple chains.

src/holograph/open-edition-deploy.ts

import { HolographOpenEditionERC721ContractV2 } from "@holographxyz/sdk";
import { networks } from "@holographxyz/networks";

import { wallet } from "./config";

const myOpenEditionContract = new HolographOpenEditionERC721ContractV2({
  contractInfo: {
    name: "NFTs Without Boundaries",
    description: "Probably nothing.",
    symbol: "HOLO",
    royaltiesPercentage: 2000, // 20%.
  },
  nftInfo: {
    ipfsImageCid: "QmQJNvXvNqfDAV4srQ8dRr8s4FYBKB67RnWhvWLvE72osu",
    ipfsUrl: "ipfs://fileurl.com/file",
  },
  salesConfig: {
    maxSalePurchasePerAddress: 10,
    publicSaleStart: "2025-01-01T00:00:00Z", // It must be in the ISO format
    publicSaleEnd: "2025-01-07T00:00:00Z",
    publicSalePrice: 25, // USD unit
  },
  primaryChainId: networks.polygon.chain,
});

const signatureData = await myOpenEditionContract.signDeploy(wallet);

const { contractAddress, txHash } = await myOpenEditionContract.deploy(
  signatureData
);
