Is there a way I can fetch all the txns happened in contract address I'm interacting with on frontend?

Yes, you need to use a multicall library or contract

example is indexed finance multicall library which can support upto 10 calls per request

check here https://github.com/indexed-finance/multicall

but this will work only calling the same contract but different functions

if you want to call different contracts addresses in the same multicall then you need to deploy your own multicall contract to handle that

I have an example here

https://github.com/decentraid/core-contracts/blob/main/contracts/multicall/ZMultiCall.sol

which I created myself

this is flexible and portable as you dont need to deploy any contract to use it

How can you do a callStatic to a non deployed contract? :o

Thought you need at least a constructor

check indexed finance method

check here, I personally use it

Oh ok ok it use a constructor

yes

and they perform the staticcall on deployment

this runs the solidity call but not actually deploying it

Yeah that's a smart move as long you only need to call views functions

Yes

for non view function, he needs his own multicall deployed

there are some deployed for general purpose such as this address multicall3
its same address is deployed on many networks
https://etherscan.io/address/0xca11bde05977b3631167028862be2a173976ca11

cool address btw 0xcaLL...caLL

cool address tho

look up eth vanity addresses if you don't know. def very cool 😎

I know vanity addresses, just complimenting it

vanity address is not that simple for contract's

yeah. if anyone's interested, this is one example
