A middleware allows customizing requests send and received from an ethereum node.

Writing a middleware is as simple as:

  1. implementing the inner method to point to the next layer in the "middleware onion",
  2. implementing the FromErr trait on your middleware's error type
  3. implementing any of the methods you want to override
use ethers::{providers::{Middleware, FromErr}, types::{U64, TransactionRequest, U256}};
use thiserror::Error;
use async_trait::async_trait;

#[derive(Debug)]
struct MyMiddleware<M>(M);

#[derive(Error, Debug)]
pub enum MyError<M: Middleware> {
    #[error("{0}")]
    MiddlewareError(M::Error),

    // Add your middleware's specific errors here
}

impl<M: Middleware> FromErr<M::Error> for MyError<M> {
    fn from(src: M::Error) -> MyError<M> {
        MyError::MiddlewareError(src)
    }
}

#[async_trait]
impl<M> Middleware for MyMiddleware<M>
where
    M: Middleware,
{
    type Error = MyError<M>;
    type Provider = M::Provider;
    type Inner = M;

    fn inner(&self) -> &M {
        &self.0
    }

    /// Overrides the default `get_block_number` method to always return 0
    async fn get_block_number(&self) -> Result<U64, Self::Error> {
        Ok(U64::zero())
    }

    /// Overrides the default `estimate_gas` method to log that it was called,
    /// before forwarding the call to the next layer.
    async fn estimate_gas(&self, tx: &TransactionRequest) -> Result<U256, Self::Error> {
        println!("Estimating gas...");
        self.inner().estimate_gas(tx).await.map_err(FromErr::from)
    }
}

If one of these types is not used, decoding will fail and the method will return an error.
