Devnet Chain ID Change from 0 to 1119889111

We’re changing devnet’s Chain ID from 0 to 1119889111 on Wednesday, January 29 at 9:00 AM PT.

Currently, both devnet and testnet share a Chain ID of 0, making it difficult for apps to identify which network they’re connected to. This change fixes that.

What to expect:

  • We expect minimal impact. You may just need to restart any services that query the Chain ID.
  • If we hit unexpected issues, we’ll revert the change and schedule a full devnet reset for February.

Going forward, Chain ID will be the standard way to identify networks. We won’t be supporting RPC hostnames as a network identifier.
