Brane SDK Code Review

Architecture Overview

Brane is a type-safe Ethereum SDK for Java 21. The codebase follows these principles:

• Zero external dependencies in public APIs - Only JDK and Brane types exposed
• Immutable value types - Records for data, no mutable state in public types
• Explicit error handling - Typed exceptions, no silent failures
• Thread-safe by default - Safe for concurrent use without external synchronization
