go-ethereumversions. - Step 3: Update the
go-ethereumdependency in your project'sgo.modfile (or equivalent) in a development environment. - Step 4: Test application functionality that uses
go-ethereumwith the updated version. - Step 5: Deploy the updated application with the new
go-ethereumversion to staging and production. - Step 6: Monitor application stability after the
go-ethereumupdate.

go-ethereumand its transitive dependencies, for known vulnerabilities. - Step 3: Run dependency scans regularly, ideally in CI/CD, to check
go-ethereumdependencies. - Step 4: Review scan results, prioritizing vulnerabilities in
go-ethereumor its dependencies. - Step 5: Investigate fixes for

Impact:
- Application Instability due to Unhandled Errors: Significantly reduces risk. (Robust error handling prevents crashes from
go-ethereumerrors.) - Information Disclosure via Error Messages: Partially reduces risk. (Abstracting messages reduces disclosure, secure logging also needed.)
