Summary of Changes

Hello @Dargon789, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a foundational architectural shift, reorganizing the project's modular components and modernizing its development toolchain. The changes aim to improve maintainability, standardize code quality, and provide robust infrastructure for future feature development, particularly around multi-version wallet management and enhanced testing capabilities.

Highlights

• Monorepo Structure Overhaul: The project has undergone a significant refactoring, moving several packages (e.g., abi, api, auth, core, guard, indexer, metadata, relayer) into a new top-level 0xsequence package. This centralizes core components and simplifies dependencies.
• Build System Transition to Preconstruct: The monorepo's build management has shifted from turbo to preconstruct, introducing new scripts for building, watching, releasing, and versioning packages, streamlining the development and release process.
• Standardized Code Quality and Testing: New ESLint, Prettier, and Babel configurations have been added or updated to enforce consistent code style. A comprehensive browser-based testing infrastructure, including new test files and a Webpack test server, has been integrated to enhance testing coverage and reliability.
• Introduction of @0xsequence/account Package: A new @0xsequence/account package has been added, providing advanced functionality for managing multi-network wallets, including versioned configurations, migration paths, and enhanced signer capabilities.
• Core Package Enhancements for Wallet Versions: The @0xsequence/core package now includes distinct v1 and v2 implementations for wallet configurations and signatures, along with common utilities for context, readers, and transaction handling, enabling support for different wallet versions and migration strategies.

Code Review

This pull request introduces a significant refactor and update to the project's development and build infrastructure, alongside core library changes. Key updates include migrating the monorepo build system from turbo to preconstruct, updating CI/CD configurations in .circleci/config.yml and lefthook.yml, and overhauling linting (.eslintrc.js) and formatting (.prettierrc) rules. The package.json reflects these changes with new scripts and dependencies, notably adding @tanstack/react-query, geth, viem, and wagmi. Documentation has been extensively updated in README.md and packages/0xsequence/README.md to reflect new workflows and testing instructions. Core library changes involve restructuring the 0xsequence package to re-export its sub-packages, and updates to the Account and Session classes, including new nonce selection logic and EIP-6492 support. Review comments highlight several areas for improvement: critical warnings about potential issues with API validation of v2 signatures, complex signature chaining logic, and the misuse of updateImageHash. There are also suggestions for improving test coverage (e.g., for wallet functionality, error responses), making hardcoded chain IDs configurable, addressing a LocalRelayer gas price re-estimation behavior, and clarifying documentation for complex logic and API limitations. Additionally, comments point out redundant test calls, unused imports, and a commented-out test utility file, suggesting further code cleanup and optimization.
