Monitor EVM transactions

[sveitser]

We currently do have some retry logic but I think it's not enough in case we send a mispriced transaction. Unfortunately doing robust EVM transaction monitoring and re-submission is not exactly straightforward and I have so far not found an existing solution that seems viable.
