Difference between Contract and ContractFactory ???

[Sairam002]

Hi all,
In lesson-8 at 13:13:47 I came across a new keyword Contract.
I wanna know what is the difference between Contract and ContractFactory ??

Since both require abi, address , signer

For contract :-

const contract = new.ethers.Contract(abi, address, Signer); 

For ContractFactory :-

const contractFactory = new.ethers.ContractFactory(abi, address, Signer);

Can somebody please help me??

Another question
@PatrickAlphaC Can you help me answering this question??

In same lesson at 13:25:37 at line number 49 the anonymous function takes transactionReceipt as input.
Previously when @PatrickAlphaC discussed difference between transactionResponce and transactionReceipt you mentioned that
after transactionResponce if we wait for few blocks to mine, then we get is transactionReceipt

Code :-

const transactionReceipt = await transactionResponce.wait(1);

But at 13:25:37 you didn't wait for few blocks to mine!!!

Now my question is ... How did you get the output for*

transactionReceipt.confirmations

without declaring???

A Contract is an abstraction of code that has been deployed to the blockchain. Which only requires ABI, address, and signerOrProvider.

But in order to deploy that contract additional information is needed that is not available on a Contract object itself. Mainly, the bytecode of a contract is required.

[PatrickAlphaC]

Contract is a Contract object, and it allows you to call functions and interact with a contract.

const contract = new.ethers.Contract(abi, address, Signer); 

ContractFactory is a ContractFactory object, and allows you to deploy contracts.

const contractFactory = new.ethers.ContractFactory(abi, address, Signer);

ContractFactory: Deploys Contracts
Contract: Is a contract

Can you ask your 2nd question in a new thread?
