Inconsistent Error Handling Patterns

[ISTIFANUS-N]

Files: Across all contract modules
Severity: High
Category: Code Quality & Maintainability

Description:
Different modules use inconsistent error handling approaches.

Acceptance Criteria:

• Standardize error handling across all modules
• Create common error types and patterns
• Implement consistent error propagation
• Add error handling guidelines to development standards
• Audit all error handling paths

Impact: Medium - Inconsistent behavior and difficult debugging

Hi,

I’d like to request assignment to this issue.

As a full-stack developer working actively in the Stellar ecosystem, I understand how important robust automation is for projects that combine Soroban smart contracts, backend services, and frontend applications. A reliable CI/CD pipeline is the backbone of safe contract development, deterministic builds, and predictable testnet releases.

During the previous waves of contributions, I worked on several Stellar-related repos where I resolved issues such as:
Frontend implementations.
Misconfigured GitHub Actions leading to failing builds
Missing or incomplete Soroban contract test pipelines
Frontend pipelines that didn’t catch build/lint errors
Inefficient caching (Rust, pnpm) that slowed down CI
Incorrect workflow permissions affecting deployment and artifact uploads
These issues helped me develop a strong sense of what healthy CI/CD should look like for blockchain projects.

Relevant Skills
Full-stack expertise with Soroban, Rust, TypeScript, and modern frontend tooling
Strong experience designing and maintaining GitHub Actions workflows
Familiar with contract testing, reproducible builds, and blockchain dev best practices
Experience with pnpm-based frontend CI pipelines (install, lint, type-check, build)
Comfortable implementing secure deployment flows, secret management, and workflow permission hardening
Confident in making pipelines faster and more reliable using smart caching strategies

ETA: 5hrs
