Hardhat Network Helpers is a library that provides a set of utility functions to interact with the Hardhat Network. You can read their full documentation here.
We recommend using npm 7 or later:
npm install --save-dev @nomicfoundation/hardhat-network-helpers
Import it and use it in any of your files. For example, this Hardhat script mines some blocks and then prints the block number.
const helpers = require("@nomicfoundation/hardhat-network-helpers");
async function main() {
// mine 100 blocks
await helpers.mine(100);
console.log("The current block number is", await helpers.time.latestBlock());
}
main().catch((error) => {
console.error(error);
process.exitCode = 1;
});
