Deprecation of Goerli networks

Hello Defender Community,

As we are close to goerli deprecation timeline, we want to give heads up to the community on key dates when the goerli deprecation will happen across different networks.

  • Optimism Goerli - Mar 7th
  • Arbitrum Goerli - Mar 18th
  • Ethereum Goerli - Apr 17th

Our third party json rpc providers ( which are outside of defender's control ) will be undergoing deprecation on these dates. Defender will pause all requests to these networks and no longer be able to make any json rpc requests after these dates. Please migrate your resources from goerli to sepolia on all these networks if you haven't already done so and if you have any questions please reach out to

We will update dates for other networks as soon as we get more information on when node providers will stop accepting our json rpc requests.
