How to interact with a Contract as a contract ?

[Willgg]

Suggestion

Hi everyone,

I am writing tests for my contracts and I need to call .mint() as a contract (not EOA). I tried :

const swapFactory = await ethers.getContractFactory('Swap')
const swap = await swapFactory.deploy()
await swap.deployed()

const contractSigner = await ethers.getSigner(swap.address);
await token.connect(contractSigner).mint(account.address, amount);

After running npx hardhat test I get this error :
InvalidInputError: unknown account 0x5fbdb2315678afecb367f032d93f642f64180aa3
I assume the last line including toke.connect(contractSigner) where the error is from.

Any idea how to call a contract as a "contract signer" the good way ?

Thanks a lot

Maybe this is an impossible use case as contract-to-contract only occurs within a contract context. In that case just let me know ;)

The ethers.getSigner util is added by hardhat and it is not present in the ethers.js codebase.

Yeah I think it's possible but before that you need to use hardhat_impersonateaccount first. Then ethers.getSigner on a contract address would work.

(Moving to discussions since this is not an ethers.js issue).
