Interesting! That’s good to know. We currently use bor nodes for our MEV infrastructure. I was under the impression that 2.0 would involve a pivot away from geth (bor) and towards an erigon-based execution client. But I’m sure we could set up the relay so that we could move the module from geth to erigon with minimal refactoring.
I’ll discuss with my team - this type of infra layer would be a fun project.
