Worked on stabilizing the smart wallet configuration for the goat-sdk/goat repository by addressing a critical environment setup issue. Focused on environment configuration using TypeScript, the developer identified and resolved a missing SIGNER_WALLET_ADDRESS variable in the .env.template, which had previously caused initialization errors for new developers. By ensuring this variable was consistently defined, the update improved the reliability of project onboarding and reduced the risk of configuration-related bugs. The work did not involve new feature development but demonstrated attention to foundational setup and developer experience, emphasizing robust environment management practices within a TypeScript-based codebase for smart wallet integration.
