Crate eth_prices 

eth-prices is a pricing library & routing engine for EVM assets.

This crate currently exposes protocol-specific quoters that can read a rate at a specific block height.

Overview

Here is a simple example showing off some of the features of eth-prices:

use eth_prices::{quoter::Quoter, token::Token};
use alloy::primitives::address;

let quoter = UniswapV3Quoter::from_pool(address!());

Today, the main building blocks are:

• quoter::Quoter for single-hop quote sources.
• quoter::QuoterInstance for storing heterogeneous quote sources together.
• token::TokenIdentifier for identifying ERC-20, fiat, and native assets.
• token::Token for token metadata and amount formatting helpers.

Quoters

Currently supported quoters include:

• quoter::fixed for static conversion rates.
• quoter::uniswap_v2 for Uniswap v2 pairs.
• quoter::uniswap_v3 for Uniswap v3 pools.
• quoter::erc4626 for ERC-4626 vaults.

Routing

Routing is currently in-progress and will be available in a future release.
