How to run a stateless transition with the current state in reth-exex

[djm07073]

Hello, I’d like to simulate some contract code using exex. What’s the recommended way to use the block executor with the current state? I need to run a stateless transition based on the current EVM database

fn main() -> eyre::Result<()> {
    reth::cli::Cli::parse_args().run(|builder, _| async move {
        let handle = builder
            .node(EthereumNode::default())
            .install_exex("...", move |ctx| async {
                let mut block_executor = ctx.block_executor().clone();
                // block_executor. ??
            })
            .launch().await?;

        handle.wait_for_node_exit().await
    })
}

Also, when my node is still syncing, reth-exex might end up simulating against an outdated state from a peer. I’d like to run simulations only against the latest block state (not the committed block, which I understand is already exposed via ExEx notifications).

Is there a way to access the most recent block from a connected peer during sync, so that I can simulate using that up-to-date state instead of an older one to avoid a unnecessary simulation?

gotcha

                    let database_provider = ctx.provider().database_provider_ro()?;
                    let provider = LatestStateProviderRef::new(
                        database_provider.tx_ref(),
                        database_provider.static_file_provider().clone()
                    );
