Reth token tax

Having recently taken an interest in Rust and Reth, I decided to take advantage of its modularity to add some custom code. This code adds a new custom eth_tokenTax api to the rpc eth namespace. At the moment, only token/weth pairs on UniswapV2 are supported.

Acknowledgements

This project is based on the Univ2-Tri-Arb repo from duoxehyon for retrieving univ2 token taxes, as well as on the examples provided in the reth repo.

Build

cargo run -- node --http --http.api web3,eth,trace

And call the method with cast or curl:

cast rpc eth_tokenTax '["0xaC1419Ee74F203C6b9DAa3635ad7169b7ebb5C1A","0x1396D6F2e9056954DFc2775204bB3e2Eb8ab8a5B","0x1151CB3d861920e07a38e03eEAd12C32178567F6","0x72e4f9F808C49A2a61dE9C5896298920Dc4EEEa9"]' | jq
