Change checklist

• I have performed a self-review of my own code,
• I have made corresponding changes to the documentation. All new code adheres to the team's documentation standards,
• I have added tests that prove my fix is effective or that my feature works (if possible),
• I have made sure the CHANGELOG is up-to-date. All user-facing changes should be reflected in this document.

Summary by CodeRabbit

• Chores
  • Removed an unused dependency and replaced internal display/formatting macros with an alternative implementation across the codebase.
  • Changes are internal (derive/formatting adjustments and minor docs) with no user-facing behavioral changes expected; maintenance and build consistency improved.

Walkthrough

Removed the displaydoc dependency and replaced displaydoc::Display derives with derive_more::Display, updating display attribute syntax (e.g., #[displaydoc("...")] → #[display("...")]) across several enums and structs; Cargo.toml no longer lists displaydoc = "0.2".

Changes

Cohort / File(s)	Summary
Dependency Cargo.toml	Removed displaydoc = "0.2" from [dependencies].
Display derive updates src/networks/mod.rs, src/rpc/methods/eth/types.rs, src/rpc/reflect/mod.rs, src/shim/address.rs	Replaced displaydoc::Display with derive_more::Display. Converted #[displaydoc("...")] attributes to #[display("...")], adjusted format placeholders (e.g., {0:#x} → {_0:#x}) and removed per-variant displaydoc attributes where applicable.

88-112: Add #[display(rename_all = "snake_case")] to match serialization output.

The #[serde(rename_all = "snake_case")] only controls JSON serialization; it doesn't affect the Display implementation. Without an explicit #[display(...)] attribute, derive_more::Display will output variant names in PascalCase ("Admin", "Sign", etc.). Add the enum-level attribute to ensure consistency.

62-76: Add explicit #[display(...)] attributes to NetworkChain variants to preserve lowercase output.

The migration from displaydoc to derive_more::Display removed custom formatting. Without explicit #[display(...)] attributes, unit variants will display as capitalized variant names (e.g., "Mainnet"), breaking the network_chain_display test which expects lowercase names (e.g., "mainnet"). The Devnet(String) variant will work correctly as derive_more forwards single-field tuples to the inner type's Display.

Suggested fix

 pub enum NetworkChain {
     /// mainnet
+    #[display("mainnet")]
     #[default]
     Mainnet,
     /// calibnet
+    #[display("calibnet")]
     Calibnet,
     /// butterflynet
+    #[display("butterflynet")]
     Butterflynet,
     /// devnet
     Devnet(String),
 }
