Hardhat Ethers

[Atharv-02]

Hi Sir,
will it be wrong if while using hardhat ethers we do not write

await simpleStorage.waitForDeployment();

[alfaqi]

We have to wait for block to be confirmed (or registered and indexed) to interact with the contract.

so what is the difference between ---

 await simpleStorage.deploymentTransaction().wait(6);

and ----

await simpleStorage.waitForDeployment();

[alfaqi]

1- await simpleStorage.deploymentTransaction().wait(6);
baseContract.deploymentTransaction()⇒ null | ContractTransactionResponse
Return the transaction used to deploy this contract.

This is only available if this instance was returned from a ContractFactory.

2- await simpleStorage.waitForDeployment();
baseContract.waitForDeployment()⇒ Promise< this >
Resolve to this Contract once the bytecode has been deployed, or resolve immediately if already deployed.
