Warning
Wormhole Contributors recommend that all connected chains implement robust security practices, including (but not exclusively):
- Open-sourcing code and running public bug bounty programs
- Undergoing security audits and publishing those reports
- Using version control with adequate access controls and mandatory code review
- High unit and integration test coverage, where the results of those tests are available publicly
Chains that can't verifiably prove they meet most of these may be marked with a 
symbol.
Wormhole integrators are encouraged to understand the security assumptions of any chain before trusting messages from it.
See Wormhole’s security program for recommended practices.
