How to deploy a Safe on Hardhat

Question

I am developing a Safe Module and would like to use Hardhat to test it. However, I have been so far unable to deploy a Safe using Hardhat. Does anyone have experience doing this? Even when I set my chainId to a chain I know SafeFactory exists for, I experience the error of Invalid Safeproxyfactory Address.

We run some Safe tests using Hardhat Network in our project. Here is the example: safe.spec.ts#L212

You have to deploy 3 contracts:

• GnosisSafeProxyFactory.sol
• GnosisSafe.sol
• MultiSend.sol

Then you provide the addresses and the ABIs for Hardhat chainId to gnosis SDK

import { SafeFactory } from '@gnosis.pm/safe-core-sdk'

// Initialize the Adapter and provide the deployed contract infos

const safeFactory = await SafeFactory.create({
    ethAdapter,
    contractNetworks: {
        [client.chainId + '']: {
            multiSendAddress: multiSendContract.address,
            multiSendAbi: multiSendAbi,

            safeMasterCopyAddress: safeContract.address,
            safeMasterCopyAbi: safeAbi,

            safeProxyFactoryAbi: proxyFactoryAbi,
            safeProxyFactoryAddress: proxyFactoryContract.address
        }
    }
});
