Hey guys, do any one know how to keep the forked mainnet in sync with the actual mainnet using hardhat or some other means

You'll need to keep forking to update it to the current state...

Can you explain a bit more , thanks in advance

Or resources will be great

...

The forked instance only has data at the last block when the fork was done, so in order to have the fork in sync you'll need to run the fork command again before you execute the code you want to test...

But cant we write any script to the keep the node in sync

Lets say new block is added to the mainnet so it automatically reflects in the local node

No, the command is done from a different shell while the code you are testing is done from a different shell...

Lets say i have some staking contract if i deposit in 1st block i want to check after some time how can i do that using the fork?

I have to deposit and chekc the earned rewards using the fork only

Is it possible @Daphantom

Do you have any idea about it

Every interaction you have with the forked instance mines a new block...

Yes...

Both hardhat node and anvil have methods to increase block number

You don't need a fresh fork for that

But will this in sync with the orginal mainnet ?

Okk ,does it also reflects the mainnet transaction in the forked local net

no

take a look at https://book.getfoundry.sh/reference/anvil/
but getting updates into a fork from a network is something i've not seen around.
Also why would you need it? you can simulate actions or use snapshots

Thats a good question but imagine stimulation the various scenarios change the price locally using oracles and check the status of the various function on the defi protocols or lending and borrowing protocols and warning the platform earlier

you reset the fork each block and run what you need to run on it again =)

there's also anvil_dumpState & loadState, maybe those can speed up the process

Yehh will try and get back

As far as you remember is they any other process that we can achieve the above

no, when i need fresh states i reset the fork and run the scripts again.
On tests i don't pin the block in the fork

uh, just tried dump&load
seems a faster way then re-launching the scripts.
Dunno about conficts or anything
