Also, consider trying ic-alloy to interact with the EVM. It adds a layer on top of the EVM RPC canister calls to make interactions easier.

Getting latest block number:

github.com

ic-alloy/ic-alloy-toolkit/blob/main/src/backend/src/service/get_latest_block.rs

use alloy::{
    providers::{Provider, ProviderBuilder},
    transports::icp::IcpConfig,
};

use crate::get_rpc_service_sepolia;

/// Request the latest block from Eth Sepolia.
#[ic_cdk::update]
async fn get_latest_block() -> Result<String, String> {
    let rpc_service = get_rpc_service_sepolia();
    let config = IcpConfig::new(rpc_service);
    let provider = ProviderBuilder::new().on_icp(config);
    let result = provider.get_block_number().await;

    match result {
        Ok(block) => Ok(block.to_string()),
        Err(e) => Err(e.to_string()),
    }
}
