Hi, I’ve recently completed and merged backend infrastructure work in the Stellar Wave program, and I’d like to work on this API standardization task as well.

I can implement a unified API response envelope and global error handling in a way that’s consistent, minimally invasive, and aligned with the existing architecture.

Approach:

• Introduce a standard { success, data, error } response format using a global interceptor or middleware
• Define typed error codes for bridge and adapter failures
• Apply a global exception filter to normalize error responses
• Ensure existing endpoints continue to work with minimal changes

I’ll focus on clarity, consistency, and avoiding unnecessary refactors.

ETA: 1–2 days after assignment.
