🎯 Problem to be solved

Charon currently doesn't have a reliable way to handle beacon node failures, which could lead to interruptions. We need to improve Charon's ability to switch to backup beacon nodes when the primary node fails.

🛠️ Proposed solution

  • Implement a "pick list" feature in Charon for fallback beacon nodes
  • Allow users to specify a list of primary and fallback beacon nodes through configuration
  • When a call to a primary beacon node fails, automatically try the next available node from the fallback list
  • If all nodes in the list fail, report the failure to Charon
  • Ensure this feature works with the existing "multi" component that handles multiple beacon node connections
  • Add error handling and logging for fallback node selection
  • Update documentation to explain how to use and configure the fallback beacon node feature
  • Create tests to verify the fallback mechanism works as expected

app/eth2wrap: fallback beacon nodes (#3342)
6a0caf4 
Implement a way to provide eth2wrap with two classes of beacon nodes addresses: standard and fallback beacon nodes.

When one of the multi BN calls fails, eth2wrap wrappers will try to get an available fallback BN from a list and re-do the call on that.

If no fallback BNs is specified, return the original error.

If the fallback BN call fails, return fallback error instead.

This PR firstly introduces concepts and code, will introduce CLI parameters and initialization code later.

app/eth2wrap: add CLI support for fallback beacon node (#3459)
06233ce 
Add `--fallback-beacon-node-endpoints` CLI flag to specify a list of beacon nodes to use if the primary list (specified using `--beacon-node-endpoints`) fails.

This is the continuation of a previous PR (#3342) which added the fallback logic.
