Uniswap V3 SDK Rust

Rust CI docs.rs crates.io

A Rust SDK for building applications on top of Uniswap V3. Migration from the TypeScript Uniswap/v3-sdk.

It is feature-complete with unit tests matching the TypeScript SDK.

Features

  • Opinionated Rust implementation of the Uniswap V3 SDK with a focus on readability and performance

  • Usage of alloy-rs types

  • Reimplementation of the math libraries in Uniswap V3 Math In Rust based on optimizations presented in Uni V3 Lib

  • Extensive unit tests and benchmarks

  • An extensions feature for additional functionalities related to Uniswap V3, including:

    • pool module for creating a Pool struct from a pool key and fetching the liquidity map within a tick range for the specified pool, using RPC client
    • position module for creating a Position struct from a token id and fetching the state and pool for all positions of the specified owner, using RPC client, etc
    • price_tick_conversions module for converting between prices and ticks
    • ephemeral_tick_data_provider module for fetching ticks using an ephemeral contract in a single eth_call
    • ephemeral_tick_map_data_provider fetches ticks in a single eth_call and creates a TickMap
    • tick_map provides a way to access tick data directly from a hashmap, supposedly more efficient than TickList

Getting started

Add the following to your Cargo.toml file:

uniswap-v3-sdk = { version = "2.7.0", features = ["extensions", "std"] }

Usage

The package structure follows that of the TypeScript SDK, but with snake_case instead of camelCase.

For easy import, use the prelude:

use uniswap_v3_sdk::prelude::*;

Note on no_std

By default, this library does not depend on the standard library (std). However, the std feature can be enabled to use thiserror for error handling.

Contributing

Contributions are welcome. Please open an issue if you have any questions or suggestions.

Testing

Tests are run with

cargo test

for the core library. To run the tests for the extensions, use

cargo test --all-features --lib extensions -- --test-threads=1

To test a specific module, use cargo test --test <module_name>.

Linting

Linting is done with clippy and rustfmt. To run the linter, use:

cargo clippy --all-targets --all-features -- -D warnings
cargo fmt --all -- --check

Benchmarking

Benchmarking is done with criterion. To run the benchmarks, use cargo bench.
