In my Hardhat project, I'm using the hardhat-deploy plugin to manage named accounts, and I need to obtain signer objects associated with these named account addresses to interact with my smart contracts. Typically, to get signers, I would use:

const [owner, addr1, addr2] = await ethers.getSigners();

However, I want to be able to convert a named account address directly into a signer object, as I would with the above method, so that I can use it to connect to a contract like so:

await contract.connect(signer).method();

How can I retrieve a signer for a specific named account using its address?

To obtain a signer object from a named account address in a Hardhat project with the hardhat-deploy plugin, you can use the ethers.getSigner method, which is designed to work with the addresses of the accounts that Hardhat manages. Here's how you can do it:

// First, retrieve the named accounts using the hardhat-deploy plugin
const namedAccounts = await getNamedAccounts();

// Now, use ethers to get the signer for the 'deployer' named account
// namedAccounts.deployer returns the address for the deployer named account
const deployer = await ethers.getSigner(namedAccounts.deployer);

// You can now use the signer to interact with your contracts
await contract.connect(deployer).method();

In this example, namedAccounts.deployer provides the address of the deployer account, and ethers.getSigner returns the signer object associated with that address. This works because Hardhat knows the private keys of the named accounts for the Hardhat network environment. Remember that this approach is suitable for local development and testing purposes where Hardhat manages the private keys of the accounts.

For live networks or addresses not managed by Hardhat, you would need the private keys to create a new ethers.Wallet instance connected to the appropriate provider, or in a hardhat local or forked node you can use hardhat_impersonateAccount to get the signer for an account you don't control to mock control on the hardhat node.
