## Features 🌟

- Customized RPC server list, retry count, chain ID
- Get detailed information on the Ethereum blockchain
- Query transaction details
- Real-time tracking of the latest block height

## Usage 💡

- First, install Wall-Echain
  1. Cargo.toml
     ```toml
     # Cargo.toml
     [dependencies]
     wall-echain = "0.1.2"
     ```
  2. Cargo add
     ```shell
     Cargo add wall-echain
     ```
- Next, you can use the following code to query the latest block height on the ethereum blockchain.

  ```rust
  let w = Wall::new(Vec["https://cloudflare-eth.com/".to_string()],None, None);
  if let Some(t) = w.get_latest_number().await {
    println!("{:?}", t);
  }

  ```

- You can also use the following code to query transaction details by transaction hash.

  ```rust

  let w = Wall::new(Vec["https://cloudflare-eth.com/".to_string()],None, None);
  if let Some(t) = w.get_transaction_receipt_for_hash("0x80fdaa7f5f54cbe28b84f41afb9543cf0c9eb0d9f4b8a620c2fb5faf0b1c2810").await {
    println!("{:?}", t);
  }

  ```

- You can also use the following code to query block information by specifying the block height.

  ```rust
  let w = Wall::new(Vec["https://cloudflare-eth.com/".to_string()],None, None);
  if let Some(t) = w.get_transactions_for_block("0xe5b544", false).await {
    println!("{:?}", t);
  }

  ```
