The tutorial assumes you have some familiarity with coding, but are brand new to the world of Web3 and smart contracts. Next, define some common helpers that we can reuse in later pieces of code. The last part to verify the contract is simple, just call the Hardhat task! The typed signature request will be different depending on which contract you're interacting with. Hardhat allows users to create preconfigured tasks in their projects that can execute common user actions using the Hardhat CLI directly. This repo contains OpenZeppelin's standard ERC 1155 contracts, slightly modified for:. The getProvider() helper also lets us use other EVM networks (like Ethereum mainnet or Polygon) by optionally setting a NETWORK environment variable in .env. Read more about that in the ethers.js documentation. Here, you'll see the 'Contract Address'. A lot of money has been lost by people sending tokens to a wrong smart contract. so is it true we can no longer create our own contracts on OpenSea ?! The tutorial assumes you have some familiarity with coding, but are brand new to the world of Web3 and smart contracts. Understanding the statistics of a contract's tokens and what they convey.

On OpenSea, each user has a "proxy" account that they control, and is ultimately called by the marketplace contracts to trade their items. This poses several dangerous security vulnerabilities, such as users other than yourself being able to withdraw funds from the smart contract. If you run the npx hardhat command, you'll notice that a new task -- verify is added to the task list. Leveraging the ERC721 standard to make your items instantly tradeable on OpenSea. If you haven't already, go back to the previous step in this tutorial and follow along to set up and deploy your own NFT contract.

A contract that adheres to the ERC721 standard can have extra functions for other stuff, but must have a standard set, which includes how to enumerate who owns what. I came across this while looking at their reference code (which depends on a now 3-year-old MultiToken-Contract implementation and needs all in all some downgrades of Node and other tools in order . - First 50 are FREE, Next 350 are 0.001eth - Reveal in 12 hours Mint Website: https://monsterparkofficial.xyz Contract .
