Document MULTICALL3 in Filecoin Docs

[eshon]

https://www.multicall3.com/

Is currently deployed to 0xcA11bde05977b3631167028862bE2a173976CA11

See for verification: https://filfox.info/en/address/0xcA11bde05977b3631167028862bE2a173976CA11?t=3

It also needs to be verified properly here: https://filecoin.blockscout.com/address/0xcA11bde05977b3631167028862bE2a173976CA11?tab=contract (showing wrong contract from another chain - I've just flagged this to the BlockScout team)

More info about what this does is here: https://github.com/mds1/multicall

Also needs to be documented for Calibration testnet

Might be nice to start a page in the Docs that tries to keep track of all important deployed contracts on FEVM that EVM devs find useful.

Thanks! For contracts, wouldn't it be better to have them listed on explorers to keep them updated? Looking at etherscan, that seems to be the place devs look at for contract lists cc: xiangan @XORS-eng for any input and can we add this to painpoint pls?

@trruckerfling The reality is we have a lot of block explorers with varying levels of support for contract verification and also contract naming. While we can try to mandate they all list these and make them searchable, it will take a while, and would be easier for now to start a helpful list for them in the Filecoin Docs.

Got you

Seems like the link from Blockscout has been corrected. Do we want verified contracts on Calibration?

Do we want verified contracts on Calibration?

Doesn't hurt to try

FYI

From BlockScout:

Regarding the Filecoin-specific smart-contracts, the best you can do is probably to manually verify those contracts on at least one blockscout instance. That way the contract code would be added into Bytecode DB and in case of full match will be automatically found by all other instances. If there would be only partial match available, Bytecode DB returns the latest verified contract code. Besides, contracts automatically verified from Sourcify.dev are not added into the Bytecode DB unfortunately. We are planning to add such support, but it is not implemented yet

Therefore if you can verify Mainnet contracts on filecoin.blockscout.com that would be helpful. I've asked Filfox and Beryx to try to use BlockScout's EBD.

I've also asked BlockScout for a quote on a Calibration testnet instance but for now we just have Filfox and Beryx on Calibration afaik.
