cfmms-rs

cfmms-rs is a vertically integrated library for interacting with CFMMs (constant function market makers) on Ethereum. Features include:

• batch sync token pair data from Uniswap V2 and V3 through optimized smart contracts that minimize the number of RPC calls

• calculate token pair spot prices and simulate token swaps

• execute transactions Sync pairs simulate swaps, and interact with constant function market makers on Ethereum.

• Crates.io

• Documentation in progress

The core logic is contained in the following files:

• batch_requests - handles batch pool requests to the Ethereum endpoint using solidity contracts in contracts/
• dex - contains interfaces that handle dex invariants
• pool - contains pool interfaces that handle pools based on dex invariants
• abi - generates bindings for the UniswapV2 and UniswapV3 contracts
• sync - syncs multiple pool states between all dexes

Supported Dexes

Dex	Status
UniswapV2 variants	✅
UniswapV3	✅

Build, Run Tests, and Examples

1. In order to build, clone the github repo: git clone https://github.com/paradigmxyz/artemis cd artemis

2. Run tests with cargo cargo test --all

3. To run any of the examples, first set a local environment variable called ETHEREUM_MAINNET_ENDPOINT. Then you can simply run cargo run --example <example_name>.
