Chain IDs＃
The following table documents the chain IDs used by Wormhole and places them alongside the more commonly referenced EVM Chain IDs.
Note
Please note, Wormhole chain IDs are different than the more commonly referenced EVM chain IDs, specified in the Mainnet and Testnet ID columns.
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, and high unit and integration test coverage where the results of those tests are available publicly. Connected chains that can't verifiably prove that they've implemented a high percentage of these practices may be noted below with the 
symbol.
Wormhole integrators are encouraged to understand the security assumptions of any chain before trusting messages from it. See the recommended security practices for chains in Wormhole's security program.
