8// When adding a new chain:
9//   1. add new variant to the NamedChain enum;
10//   2. add extra information in the last `impl` block (explorer URLs, block time) when applicable;
11//   3. (optional) add aliases:
12//     - Strum (in kebab-case): `#[strum(to_string = "<main>", serialize = "<aliasX>", ...)]`
13//      `to_string = "<main>"` must be present and will be used in `Display`, `Serialize`
14//      and `FromStr`, while `serialize = "<aliasX>"` will be appended to `FromStr`.
15//      More info: <https://docs.rs/strum/latest/strum/additional_attributes/index.html#attributes-on-variants>
16//     - Serde (in snake_case): `#[cfg_attr(feature = "serde", serde(alias = "<aliasX>", ...))]`
17//      Aliases are appended to the `Deserialize` implementation.
18//      More info: <https://serde.rs/variant-attrs.html>
19//     - Add a test at the bottom of the file
20//   4. run `cargo test --all-features` to update the JSON bindings and schema.
21//   5. run `cargo +nightly fmt --all` to properly format the code.
22
23// We don't derive Serialize because it is manually implemented using AsRef<str> and it would break
24// a lot of things since Serialize is `kebab-case` vs Deserialize `snake_case`. This means that the
25// NamedChain type is not "round-trippable", because the Serialize and Deserialize implementations
26// do not use the same case style.
