Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.

Try running some of the following tasks:

✗ npx hardhat run scripts/deployFactory.js --network arbitrumSepolia
No need to generate any newer typings.
Factory deployed to: 0xd851C0FC5DeD867033a70626DcDFe10EF7B7f433

✗ npx hardhat run scripts/deployFactory.js --network mumbai
No need to generate any newer typings.
Factory deployed to: 0xd851C0FC5DeD867033a70626DcDFe10EF7B7f433

✗ npx hardhat run scripts/deployFactory.js --network sepolia
No need to generate any newer typings.
Factory deployed to: 0xd851C0FC5DeD867033a70626DcDFe10EF7B7f433

then, edit your scripts/vaultDeploy.js at line 5

    const factoryAddr = "0xd851C0FC5DeD867033a70626DcDFe10EF7B7f433";

and run

✗ npx hardhat run scripts/vaultDeploy.js --network arbitrumSepolia
No need to generate any newer typings.
