Running Examples

To run any of the examples, supply your node endpoint to the endpoint variable in each example file. For example in sync-pairs.rs:

    //Add rpc endpoint here:
    let rpc_endpoint = "";

Once you have supplied a node endpoint, you can simply run cargo run --example <example_name>.

Filters

filter_blacklisted_tokens

  • Removes any pair from a Vec<Pair> where either token_a or token_b matches a blacklisted address.

filter_blacklisted_pools

  • Removes any pair from a Vec<Pair> where the pair_address matches a blacklisted address.

filter_blacklisted_addresses

  • Removes any pair from a Vec<Pair> where either token_a, token_b or the pair_address matches a blacklisted address.

filter_pools_below_usd_threshold

  • Removes any pair where the USD value of the pool is below the specified USD threshold.

filter_pools_below_weth_threshold

  • Removes any pair where the USD value of the pool is below the specified WETH threshold.

Upcoming Filters
