A collection of filters to reduce invalid or poor quality AMMs on EVM chains.

Value Filters

Note: A good weth_value_in_token_to_weth_pool_threshold is a setting with a $USD value > $1000 at least. Lower than this, you are getting pools that could have poor liquidity and show inflated prices.

    pools: Vec<Pool>,
    dexes: &[Dex],
    weth: H160,
    weth_value_in_pool_threshold: U256, // This is the threshold where we will filter out any pool with less value than this
    weth_value_in_token_to_weth_pool_threshold: U256, //This is the threshold where we will ignore any token price < threshold during batch calls
    middleware: Arc<M>,
) -> Result<Vec<Pool>, CFMMError<M>> {
// --snip--
}
