  • OnEdge is a Go-tool to check for incorrect treatment of the defer-panic-recover process in Go when dealing with errors.

  • They found that you can cause serious issues (e.g. blockchain fork) if this is not done right (e.g. making global state changes in the middle of the pattern)

  • Based on how much recover() is used in status-go this shouldn’t take long to implement use.

  • A deeper look may show that we aren’t using the defer-panic-recover paradigm well.
