Add Multi-File Etherscan Verification Option

[naszam]

Description:

Add --multiple opt to dapp-verify-contract

[MrChico]

I don't think this should be the default verification method right now

[naszam]

If the proposed changes are ok, just need to explore the inputJSON a bit more, if working on the missing libraries field or trying to fix and use mk-standard-json instead to generate the inputJSON (that currently doesn't work out-of-the-box), then it will be ready for testing.

[MrChico]

the changes so far look good! With mk-standard-json accomodated as discussed this should make for a nice improvement!

I'm getting a syntax error in dapp-mk-standard-json when I try to run dapp init with the latest state of this branch:

oh, also please update the readme to mention these new options

[d-xo]

the close was an accident :woman_facepalming:

[transmissions11]

any blockers here? i much prefer multi-file verification

I don't think this should be the default verification method right now

why so? 🤔

[naszam]

Hi @transmissions11,

Thanks for your interest!

The only blocker so far is the dapp-mk-standard-json that doesn't work out-of-the-box for multi-file verification as it's used mainly in dapp-build to compile source code. We tried to adjust it but we had a blocker with the remappings to get all the imported contract dependencies (cc: @WilfredTA). The idea is to write a new script from scratch (probably in python) to generate a standard inputJSON for multi-file verification inspired by truffle-plugin-verify or hardhat-deploy and then use it inside dapp-verify-contracts instead of dapp-mk-standard-json. I think @e18r will give it a try, but feel free to jump in if you like! Thanks! :slightly_smiling_face:

[transmissions11]

Ah interesting. The compilation stuff is a bit out of my league sadly.

Thanks for all the work on this so far 🙏
