simulated.NewBackend does not support Shanghai (invalid opcode: PUSH0)

[nksazonov]

System information

Geth version: v1.14.13
OS & Version: MacOS 14.1.2 (23B92)

Expected behaviour

A contract compiled with solc >0.8.19 is deployed using the simulated.NewBackend(...).

Actual behaviour

An error invalid opcode: PUSH0 is received.

Steps to reproduce the behaviour

1. Create bindings for a contract compiled with solc v0.8.20.
2. Create a simulated backend with default settings.
3. Use this simulated backend to deploy the contract.

Also, it was confirmed that if the contract is compiled with solc v0.8.19, it IS DEPLOYED successfully.

What genesis block are you using for the network?

[nksazonov]

I use the default one, i.e. this one.

Ah you should use the new simulated backend v2: https://github.com/ethereum/go-ethereum/blob/master/ethclient/simulated/backend.go should be a drop-in replacement for the old sim backend

[nksazonov]

If I understand correctly, I am already using it by having go-ethereum@v1.14.13. The file at the link you have shared differs from what I use only by this commit, which does not seem to change the support of different EVM versions.

Do you maybe have a repro code/example?
