 :::warning
 In order to retrieve blocks posted to L1 via non-standard contract interactions, it is necessary to have access to an L1 rpc endpoint with 'trace' capability (either `trace_transaction` or `debug_traceTransaction`). The variable `ETHEREUM_DEBUG_HOSTS` is used to provide these url/s to the node. If not provided, the value of this will default to that set in `ETHEREUM_HOSTS`. The node will validate whether it is able to execute a trace call on the provided url/s, if not, it looks to the value set in `ETHEREUM_ALLOW_NO_DEBUG_HOSTS` to determine whether this should prevent the node from starting. By default `ETHEREUM_ALLOW_NO_DEBUG_HOSTS` is `true`, allowing the node to start. Any url provided in `ETHEREUM_DEBUG_HOSTS` will only be used in the case of having to execute a trace, it won't be used in regular L1 interactions.
