Worked on the tkhq/docs repository to deliver two core features focused on documentation engineering and API design. Enhanced the Gas Sponsorship documentation by clarifying feature availability, usage limits, and transaction management for Pro and Enterprise plans, while resolving MDX rendering issues related to dollar signs to ensure accurate Markdown output. Prepared the Balances feature for general availability by updating supported chains, introducing a two-webhook model for balance changes, and clarifying reorganization event handling. Emphasized technical writing, webhook design, and transaction management, resulting in production-ready documentation that improves user onboarding and reliability for multi-chain environments. No bugs were reported or fixed.
