Ethereum

anyone ever set up a fork of mainnet to run on cloud so that it can be accessed via RPC on a port for testing? (I need a mainnet fork, and I need it accessible from more than just my local machine). strugglin to get working. Have a node running on GCP, but contract calls fail w/out reason (frontend only, curl succeeds)

This is kinda hard since you would have to use a different chain id and that makes it impossible to use real mainnet transactions since they would be invalid. On the other hand when you use the same chain id your test transactions could slip through to the "real" chain.

yeah definitely wary of using the same chain id, so have it set up to use a custom chain id and appears to work. Also a bit wary/wondering if this will mess up all the off-chain signatures like token approvals due to the chain id (tho I was able to get this to work locally for myself)
