Worked on enhancing developer documentation within the InjectiveLabs/injective-docs repository, focusing on improving the wallet creation guide and testnet endpoint references. Used Markdown and technical writing skills to update and validate testnet endpoint URLs, ensuring accuracy and reliability for developers. Consolidated wallet creation instructions by replacing external blog links with cohesive internal documentation, streamlining onboarding and reducing support queries. Added a Cosmos SDK reference to provide clearer context for users. Emphasized documentation consistency and maintainability across the repository, aligning with internal standards. The work contributed to a more accessible and reliable developer experience, particularly for those new to the Injective ecosystem.
