viem WalletClient type incompatiability with hardhat-viem functions

[0xCourtney]

I'm struggling to get the following code to work I want to be able to pass the WalletClient as a function parameter however I'm getting type incompatibility errors.

export async function deploy(
  deployer: WalletClient,
  contractName: string,
  constructorArgs: any[],
) {
  const { deploymentTransaction, contract } =
    await viem.sendDeploymentTransaction(contractName, constructorArgs, {
      client: {
        wallet: deployer, // Types of property account are incompatible. Type Account | undefined is not assignable to type Account. Type undefined is not assignable to type Account.
      },
    });

   [...]
}

Calling getWalletClient within the function and using the returned value in the config works fine, however, I don't want to do this for every single helper function.

Are you importing WalletClient from viem or hardhat-viem? Can you share a minimal reproducible example?

WalletClient is imported from viem if I try to import from hardhat-viem I get Module "@nomicfoundation/hardhat-viem" has no exported member WalletClient. The code below should be enough to reproduce the issue.

// ./scripts/deploy.ts

import { WalletClient } from 'viem';

export async function deploy(
  deployer: WalletClient,
  contractName: string,
  constructorArgs: any[],
) {
  const { deploymentTransaction, contract } =
    await viem.sendDeploymentTransaction(contractName, constructorArgs, {
      client: {
        wallet: deployer, // Types of property account are incompatible. Type Account | undefined is not assignable to type Account. Type undefined is not assignable to type Account.
      },
    });
}

Try with import { WalletClient } from "@nomicfoundation/hardhat-viem/types";
