Module ethereum 

Ethereum Client

This module provides an Ethereum blockchain client that supports Ethereum mainnet and EVM-compatible chains (Polygon, Arbitrum, etc.).

Features

• Balance queries via block explorer APIs (with USD valuation via DexScreener)
• Transaction details lookup via Etherscan proxy API (eth_getTransactionByHash)
• Transaction receipt fetching for gas usage and status
• Transaction history retrieval
• ERC-20 token balance fetching (via tokentx + tokenbalance endpoints)
• Token holder count estimation with pagination
• Token information and holder analytics
• Support for both block explorer API and JSON-RPC modes

Usage

use scope::chains::EthereumClient;
use scope::config::ChainsConfig;

#[tokio::main]
async fn main() -> scope::Result<()> {
    let config = ChainsConfig::default();
    let client = EthereumClient::new(&config)?;
     
    let mut balance = client.get_balance("0x742d35Cc6634C0532925a3b844Bc9e7595f1b3c2").await?;
    client.enrich_balance_usd(&mut balance).await;
    println!("Balance: {} (${:.2})", balance.formatted, balance.usd_value.unwrap_or(0.0));
    Ok(())
}
