Thanks @seunlanlege for the feedback
@torsten answered here, We have a PR for Nick’s method that was merged here but unfortunately given the difference in gas model, this won’t work if the transaction strongly limits both the gas and the gas price.
Until now, to iterate fast , it was easier to have the RPC outside of the client, but indeed we should consider merging it into the client now that it’s more feature complete.
the eth-rpc needs to be configured with a database_url or env setting to maintain a permanent index, it also needs to point to an archive node if there is a need to fetch old receipts. This is probably mis-configured here, we will look into it and fix this.
We will check it out
