See: https://github.com/api3dao/commons/tree/6ebc41c031105fe824132069a4fb80e0415eee78/src/eslint

Isn't this blocked by api3dao/commons#4 ?

[Siegrift]

No, it's usable. See: https://github.com/api3dao/commons/tree/main/src/eslint#getting-started and api3dao/signed-api#68

Btw. expect a lot of issues and do not be afraid to silence rules that are too noisy.
