Pushed latest updates to this branch: added simulation test coverage and refreshed dependency/lockfile updates. |
The gasPrice field was missing from the list of fields that get converted from bytes to int, causing inconsistent behavior for EIP-2930 access list transactions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The function was added but never used in the codebase. Removing to avoid dead code. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The timeout was hardcoded to 10 seconds. Users can now configure it via the request_timeout parameter (default remains 10 seconds). Also removes unused json import. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Change deprecated [tool.poetry.dev-dependencies] to [tool.poetry.group.dev.dependencies] - Add pytest ^8.0.0 as explicit dev dependency 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Introduce domain-specific exceptions for better error handling: - FlashbotsError: Base exception for all Flashbots errors - FlashbotsTransactionError: Transaction-related errors - InvalidTransactionError: Invalid/malformed transactions - TransactionSignatureError: Signature verification failures - BlockExtrapolationError: Block timestamp extrapolation errors - FlashbotsProviderError: Provider-related errors - FlashbotsRequestError: HTTP request failures Also adds explicit __all__ exports in package __init__.py. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Replace assert statements with explicit validation using custom exceptions - Replace lambda functions with list comprehensions for readability - Add return type hints to simulate() and extrapolate_timestamp() - Use sum() instead of reduce() for gas calculation - Remove unused 'reduce' import 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Replace generic exception catching with specific handlers: - requests.Timeout: Raised when request exceeds timeout - requests.ConnectionError: Raised on connection failures - requests.RequestException: Catch-all for other request errors All exceptions are wrapped in FlashbotsRequestError with context. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Document new features and changes: - Custom exception hierarchy - Explicit __all__ exports - Assert replacements with domain exceptions - Lambda to list comprehension conversions - Provider error handling improvements - Return type hints additions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
