I could only verify BSC contracts. @fedgiac please could you take a look into it? 🙏

How was deployments/polygon/GPv2Settlement.json generated? I though that this was done without deployment scripts in the past and so it shouldn't possible to have this file.

I run the script regardless (I didn't know they were deployed), and it detected it onchain and created the entries. I didn't do it manually.

FYI, polygon was actually deployed by @nlordell back when some experiments / testing was being run.

In general it looks good, including Polygon (already the fact that the addresses match is proof enough for the contracts here anyway), but I didn't have time to look into the details, so this is a soft approve only. 🙂

I could only verify BSC contracts. @fedgiac please could you take a look into it? 🙏

Unfortunately I won't be able to do this soon, my recommendations would be to try the following two things in order if the scripts don't work:

1. Use the single-deployment verification script for each contract on each chain, or
2. Use standard-json verification: the same command as above, but also appending --show-standard-json-input to the command and using the resulting file to verify the contract on the web interface directly (without scripts, some more details here for the general concept).

No need to bump version here since it won't be released as a package. But there's the v1 branch for that, so once deployed and merged we should cherry-pick to that (like here) and bump the version. Should we also update the new network guide?

[fedgiac]

Contracts were verified for the remaining networks, see #240. I didn't encounter any particular issue when verifying, the script worked out of the box except for Avalanche. Was there some specific error?

[fedgiac]

I verified all remaining contracts and I checked each entry in networks.json and it looks good. As long as the version number is restored to the current one, this PR is ready to merge.

Looks good!
