feat(compatibility): use EIP-55 checksummed address notation in Anvil and Forge outputs

[cicada-fi]

Component

Anvil

Have you ensured that all of these are up to date?

• Foundry
• Foundryup

What version of Foundry are you on?

forge 0.2.0 (fa0e0c2 2024-08-22T00:19:05.396104000Z)

What command(s) is the bug in?

forge script

Operating System

Linux

Describe the bug

Anvil and Forge use lowercase address notation in Anvil's output and when saving addresses to JSON artifacts in the cache folder. This behavior does not comply with EIP-55, which recommends using checksummed addresses.

Lowercase format is incompatible with web3 libraries like web3.py and leads to parsing errors like this:

web3.exceptions.InvalidAddress: ('web3.py only accepts checksum addresses. The software that gave you this non-checksum address should be considered unsafe, please file it as a bug on their platform. Try using an ENS name instead. Or, if you must accept lower safety, use Web3.to_checksum_address(lower_case_address).', '0x69f94e46cbc82ab02781ac4fafc3580d21f1a888')

Can I work on this ?

[DaniPopes]

This is a straightforward fix, we are still using debug formatting (:?) from legacy ethers code in some places.
With alloy, removing it will display addresses in the checksum form.

@ShantelPeters Sure, I've assigned you, feel free to comment here if you can't work on it anymore so someone else can take it.

@zerosnacks could i take this one?

Hey @DaniPopes ! Could you clarify your comment? If I get it right the issue occurs here when we serialize the Sequence type. We could either add a serialization on the Address type (assuming that we always want to output checksum format address when serializing to json or adding a serialization function for the fields in question. Or did I get something wrong?

reopening since the implemented solution caused a bug further down the line for reth users e.g. see paradigmxyz/reth#11541 (comment)

users actually expect a lowercase format and implementing variation of the format should be on the consumer/ui side, so to be decided if we should actually implement this or leave it to the user to implement the correct format

On a general note, when working on the client side I've found that consistently casting to lowercase was required when dealing with addresses sourced from external services as most of the time you likely end up with a mix between the two

[DaniPopes]

When printing addresses we use checksum by default, in JSON output we don't anymore because this caused issues, so partially fixed, partially wontfix.
