I'm a junior blockchain developer, I deployed a smart contract on Ethereum blockchain for NFT collection. How can I call reveal function to reveal NFTS using remix or ethers js ?
function reveal() public onlyOwner { revealed = true; }

From JavaScript with ethers.js, you can do this:
import yourDeployedContract from '../build/contracts/yourDeployedContract.json' import {ethers} from 'ethers' import Web3Modal from "web3modal" async callReveal() { // Get ethereum provider with Web3Modal const web3Modal = new Web3Modal(); const connection = await web3Modal.connect(); const provider = new ethers.providers.Web3Provider(connection); const signer = provider.getSigner(); // Get contract data on the network you deployed your contract on const network = await provider.getNetwork() const contractData = yourDeployedContract.networks[network.chainId] // Get smart contract let contract = new ethers.Contract(contractData.address, yourDeployedContract.abi, signer); // Call reveal method let revealTransaction = await contract.reveal(); // Wait for transaction to be complete await voteTransaction.wait(); // Rest of the code here } yourDeployedContract.json is the JSON file generated when you called "truffle migrate".
- That's was so helpful thank you, Benjamin. what is I want to interact with a contract than not mine deployed on etherscan.io that has only ABI and address? how can I get the JSON file ? Can I interact with it in the same way?David Jay– David Jay2022-03-13 14:02:03 +00:00Commented Mar 13, 2022 at 14:02
