The deployContract function returns a Promise that resolves to a newly deployed ERC721 contract on the specified blockchain network.

The function takes in the blockchain type, a private key, and a base URI for the contract's metadata. The returned contract object can then be used to interact with the deployed contract on the blockchain



Example Request and Response


Before making requests with NEST® SDK, you must have it installed.

You can install NEST® SDK using either npm or yarn. Use the following commands to install NEST® SDK:

npm install @nest25/evm-chains-lib
yarn add @nest25/evm-chains-lib


Here is an example of how to make a deployContract request using the NEST® SDK:

// import the Nest SDK
const { BulkNft } = require('@nest25/evm-chains-lib');

// create a new instance of the SDK
const bulkNFT = new BulkNft();
// call the deployContract method
const main = async () => {
    // deploy a contract on the Polygon network
    const contract = await bulkNFT.deployContract(
    // print the contract address
// call the main function

Use Cases

  • Contract deployment: The primary use case for the deployContract function is to deploy an ERC721 contract on a specified blockchain network. This allows users to create and deploy their unique tokens on a blockchain.

  • Token metadata: The deployContract function takes in a base URI parameter, which can be used to specify the metadata for the token contract. This can include information such as token name, description, and image, and is commonly used to provide additional context about a token.

  • Automated token deployment: The deployContract function can be integrated into automated deployment workflows, allowing developers to automatically deploy new token contracts as part of their continuous integration and deployment process.
