 You can use local [Blockscout](https://www.blockscout.com/) instance to debug EVM smart contracts.
 
+Some images require `ghcr` auth, login first and pass the token:

+```
+gh auth token | docker login ghcr.io -u github-username --password-stdin

 ```
 ctf bs up
 ```

 Your `Blockscout` instance is up on [localhost](http://localhost)
 
 To remove it, we also clean up all Blockscout databases to prevent stale data when restarting your tests.

 ## Selecting Blockchain Node
 
 By default, we connect to the first `anvil` node, but you can select the node explicitly

 ```
 ctf bs -r http://host.docker.internal:8545 d
 ctf bs -r http://host.docker.internal:8555 d

-Blockscout isn’t ideal for local, ephemeral environments, as it won’t re-index blocks and transactions on test reruns. The easiest approach is to set up Blockscout first, initialize the test environment, switch to the [cache](../components/caching.md) config, and run tests without restarting RPC nodes.
